Internal sound system issue

So, my iBook is about 2 years old, and has been well used (it comes with me almost everywhere). However, recently, the sound system has been acting funny. Only one of the speakers works, and the volume level varies randomly. Also, it's only sending sound to one headphone (I've checked with multiple sets of headphones that work on other iPods and computers, so it's not the headphones). Is this a hardware issue? Or is there anything I can do to try and fix it software/reformatting wise?
Thanks!

Hi !
Sorry for my poor & bad english …
Well, my iBook G4 12" 1,2 ghz, running OS 10.5 has almost the same problem for some weeks.
Facts =
Left speaker OK / Right speaker not functional
With headset : Left & Right OK but left iBook speaker still running !
Checking sound pref panel & utility sound & midi configuration, finding nothing except : playing test of speakers in "utility sound & midi configuration" very strange because if channel 2 is selected on right speaker no sound is produced, if channel 1 is selected on right speaker so LEFT speacker play
Reseting Pram & Vram did nothing.
Hardware or Software malfunction ?

  • IPhone 3GS and Nissan 2010 Bose Sound System Issue

    I have a 2010 Nissan Altima Coupe with a Bose sound system and iPod intergration. Until recently everything worked well with my iPhone 3G S, however now on occasion, the iPod function stops dead in the middle of a book or sound. When I turn the power on an off, the car iPod system is still locked. The other functions of the sound system like regular and sattellite radio work fine. When I disconnent the iPhone there is a "Check Device" message on the car system screen. The only way to unfreeze the system is to turn of the ignition and restart the car. It seemed to start doing this after I installed the iPhone iOS4 upgrade last month. Anyone else seeing this?

    Same here. Brand new Nissan Altima Coupe with the Bose PY05F premium sound system. Stuttering, staggering and flat out freezes up.

    Take each of the following steps that you haven't already tried.
    1. If you've recently plugged anything into the audio-out (headphone) port, plug and unplug it a couple of times.
    2. From the menu bar, select
     ▹ System Preferences ▹ Sound ▹ Output
    Check the settings. The internal speakers should be selected as the output device, the Mute box should not be checked, and the volume slider should be at least halfway to the right.
    3. Look inside the headphone port. If a red light is coming from the port, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a headphone mini-stereo jack of the proper size.Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
    4. Boot in safe mode by holding down the shift key at the startup chime. It will take much longer than usual. You don't have to log in; just reboot as usual (without holding any keys) when the login screen appears. (Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.)
    5. Reset the NVRAM.
    6. Reset the SMC.
    7. Reinstall OS X after backing up all data as a precaution. You won't need your backup unless something goes wrong.
    8. Make a "Genius" appointment at an Apple Store.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to bare metal from any of them.) Don’t erase the recovery partition, if present.
    *An SSD doesn't need to be zeroed.

  • Airport/Surround Sound Latency Issue

    I just set up a new surround sound system and am streaming iTunes through both my computer speakers and adjacent surround sound (Bose hooked up to a Yamaha BRX-610). Airport Express is connected to the receiver via standard audio cable hookup. Previous stereo had no delay, but I now have maybe a .5-1 second delay between the computer and the new surround sound.
    Anyone have any thoughts, ideas or fixes?
    Thanks

    Right now its using the analog. There is an input for optical but I have it connected to something else. Would this be causing the issue?
    Possibly. The digital audio stream arriving at the Express would need to be converted to analog signal via a DAC internal to the Express prior to it being output on the base station's audio port. That conversion may be the cause of the delay.
    The other cause would be the potential of Wi-Fi interference where it would introduce a significant enough level of noise to reduce the overall bandwidth ... and, in turn, potentially causing this issue as well.

  • Macbook has no internal sound

    Hi I tried to plug a speaker wire in the headphone jack osfmy friend's macbook, and there is a blue button on the volume bar like there suppose to be, however when the speaker wire is unplugged, the blue button on the volume bar disappears,, hence no internal sound. Please help.... Thanks.

    Howdy eyeso,
    It sounds like you are no longer getting audio from the built in speakers on your Mac after using an external set. I recommend the troubleshooting in the article named:
    Troubleshooting issues with no audio from built-in speakers on Macs
    http://support.apple.com/kb/ts1574
    If you are still having issues after you have confirmed the proper version of Mac OS X is installed, make sure the computer is set to play sound from the right source.
    Remove any external audio devices and cables from the USB, FireWire, or 3.5 mm audio ports.
    Open System Preferences from the Apple () menu, the Dock, or from the Applications folder on your hard drive.
    Open the Sound pane and the Output tab, then select Internal Speakers as in this image:
    If Internal Speakers is not an option proceed to step 4. For Mac Pro computers, proceed to step 5.
    If Internal Speakers is present but not selected, select it and test again.
    If the Output volume slider is low or the Mute box is selected, raise the volume slider or deselect the Mute box and test again.
    If the issue continues through these steps and Internal Speakers remains the selected option proceed to step 5.
    If the Internal Speakers option does not appear in the Output tab and your computer is not a Mac Pro, check that Digital Out is present as in the image below:
    Confirm again that all external audio devices and cables have been removed.
    Check to see if a red light is lit in the line-out port. If so, your Apple computer may need service.
    If you do not see a red light, proceed to step 5.
    If the issues persist, contact Apple support for further troubleshooting assistance.
    Thank you for using Apple Support Communities.
    All the best,

  • 5.1 Sound System with Satellite X200

    Hi,
    this is my first post here since up until now I've been able to solve all issues regarding my laptop. In the meantime, I acquired a 5.1 sound system to connect to my machine thinking it would be pretty straightforward due to all the technology implemented in this model and the SPIDF output and so on and so forth....well it wasn't :)
    I've searched online for a solution but nothing obvious came up, and I've tried just sticking the sound system jacks everywhere just to experiment and see what I get but apparently there's always only 2 speakers working plus the bass.
    Can anybody give me a hand?
    Thanks in advance, best regards from Portugal
    Bruno Belo

    Boas!
    The x200 sound system is a 2.1 system, so to have a 5.1 system you need an external decoder and bypass the internal system using the SPDIF output.
    Did you really aquired a 5.1 sound system or just a 5.1 speaker system ? If is really a decoder you should have a digital input to plug the SPDIF output and configure it to play at least 4.1 with an stereo source, an mp3 for example.
    If you only have a 5.1 speakers system(even digital) you'll need an 5.1 external sound card, some are USB interfaced others pcmcia.
    Regards from Azores ;)

  • Sound input issue

    Last week I answered a Skype call to find the person on the other end couldn't hear me. I checked all my preferences, and realised that there was no input registering for the Line In (external mic) in the Sound System Pref.
    Thinking it might be the external mic, I tried the internal one. I still have the bars registering noise, but nothing in Skype.
    Wondering if it was a Skype issue, I tried Quicktime. Trying to record audio through QT Pro gets nothing with either internal or external mic.
    But the strange thing is iMovie and Windows Movie Maker (through Parallels) record just fine from the internal (but not external) mic.
    Any ideas would be greatly appreciated. It's driving me nuts!

    What you think is a mic input on the mac is actually a line level input - so you can't just plug a mic in - it's the more pro approach to sound input.
    So you need a line level input. I'm not very familiar with what's out there, but essentially it'll be the equivalent of a preamp.
    You can also bypass the line in input entirely by getting a usb input - for example I use an Andrea sound pod for a speech recognition microphone.
    Hope that helps
    Best of luck.

  • My sound system does not work AFTER installing pc to tv wireless connection

    my sound system does not work after installing hp pc to tv wireles device when I am using lap top for other purposes.

    Hi,
    You don’t install VS2010 on the client PC, then where did the Form Invoice not work? When you run it from another version of VS? Or when you run the application with application.exe?
    Based on your description, one form works well, another form does not. I assume that two forms are in two different projects, then please check the .Net Framework used by the two projects. If they are different, you can use the
    one used by the Form contact for Form Invoice.
    Because this issue is a project issue, I recommend you to consult it on some application forum such as Windows Forms General forum for better support.
    VS General Question forum mainly discusses
    the usage of Visual Studio IDE such as
    WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help
    System and Visual Studio Editor.

  • Itunes won't play anymore through external sound system

    My mac functions as a Protools recording studio. The hardware (a Digi002 system) attaches to my G5 by firewire. Until recently, itunes worked just fine playing through this external system. I'd simply go to system preferences, change the sound inputs and outputs to Digi002.
    These days I can still get all of my pro music software to play through this external Digi002 system. But something has gone amiss with itunes. It doesn't matter if itunes is already open, or not yet open. If I go to sound preferences and switch it to DIGI002, itunes ONLY plays through my internal compouter speaker. And if i go back to the sound preferences, i find that the external audio choice had been unchecked, as if by some function within itunes itself.
    i have asked this same question on the Protools forum. Respondees give mixed answers, but basically say, yes it used to work, and no, it no longer works. Some say it WILL work, but you have to fire up your sound system BEFORE you turn on your computer. That is a totally disfunctional "solution" for my situation. Who wants to keep a sound system on all day long, when I may not use it for several hours at a time?
    So what's going on here? And what did I install that made itunes suddenly not function with my external system? I strongly suspect it may be some newer version of itunes itself. If so, is there some workaround utility that will let me re-connect itunes to the Digi system? any help is appreciated.

    Hate to do this, but we've gotta start with the simple **** first, and work our way up. The volume control in iTunes isn't turned down, is it?
    Aside from that, you should launch Quicktime Player, go to File - Open, and open one of your iTunes songs in that, and see if you can hear sound there.

  • To everyone with IOS6 Sound related issues & Others

    If you are facing a problem of not having any system sounds, notification sounds, no calls or other software sound related issues I'd suggest you read below it's a stupidly simple fix and it should solve most software issues after an immediate iOS6 update:
    After updating unplug the phone from your computer and leave the phone alone for 5-10 minutes, if you still have problems: reboot, wait a few minutes and all sound related problems should be fixed.
    When I updated to iOS 6 I had lost my system sounds, so I unplugged from the computer, rebooted the phone and still no go. I decided to just let the system "settle in" for a bit, let it lock and when I unlocked after 5-10 minutes sounds were back and everythings up and running again.

    Well, to break it down. After my sounds finally came back (2nd time losing them) last night I decided to restore the phone in itunes. I did it twice. First time I backed up my data. Second time I restored it as a factory iPhone. Both times guess what NO SOUNDS! I also realized that last night I had lost my sounds after charging my phone and unplugging it from the data cord. I still have ringtones (when someone calls), but text messages, emails, and any other alert tones do not work. I cannot turn the volume up or down with the side buttons and also music does not play. It doesn't even have a slide bar at the bottom.
    I am on the phone with apple care now. They seem to not be aware of the problem at all.
    While I was on the phone with them my sounds ended up coming back, imagine that. Hopefully every time I charge my phone I am not going to have this issue.

  • Beats-Audio / Sound System Enhancement dv7 / HP Envy 15

    Beats-Audio - Sound system Enhancement
    Test system
    dv7t – 6100 Quad / Windows 7- 64bit
    Beats-audio
    Introduction - Cave Sound Caper
    Edits 29-Nov-2011
    This is a re-write of this document. 
    Parts One and Two have been flipped.  It's a work in progress.
    The purpose of this Post is to provide a method to enhance the sound coming from your onboard beats-audio speakers.  The quality of the sound should improve - more importantly, MORE sound should be available.  This is important if your system is suffering from lack of enough sound from the onboard speaker system.
    This process does not make use of the Loudness Equalization enhancement.  I tested the Loudness Equalization enhancement (for a different purpose).  Setting the enhancement on my test system and then switching the enhancement off resulted in the “Low Sound” syndrome.  It took some amount of work to recover from that mess. The Loudness Equalization enhancement, in this author's opinion, is to be avoided unless its use is necessary.
    FLIPPED:
    The original intent of this procedure has been to provide a means to increase the amount of sound available from the onboard speakers on notebooks that are equipped with beats-audio IDT sound drivers.  The “Pre-work” on my original post was overwhelming the intent.  If your system is healthy, and the only reason to read this document is to enhance the amount of sound from the speakers, there is no need to hash through the work to fix your IDT driver installation.  I’ve moved that section to the end – IDT installation and other work has become Part Two.
    You must have your IDT HD driver successfully installed into your system.   The proper IDT HD driver contains the beats-audio interface.
    Where to Start?
    If you have “No Sound”, the Enhancement process may not work for your system.  Please take a look at Part Two and decide whether any of the steps in that section apply to you.  It is not my intention that you waste your time trying things you’ve already done over and over to regain the sound on your system.  There are many posts on the forum on how fix “No sound”.  This post addresses only a couple of “No sound” issues.   There is one slight possibility – see the section about the controls in iTunes – make sure your sound players volume controls are not mis-matched – and make sure you didn’t turn something OFF by accident.  If you turned off the sound while watching a movie and now the HDMI sound is off  - Poof!  You might not have any sound – anywhere.  It's just something to check...
    If you have “Low Sound”, you might consider reinstalling your IDT driver to see if the issue can be corrected: IDT reinstallation is described in Part Two.
    SideBar:  As of 24-Nov-2011
    If you have a dv7t: check on your HP Software and Driver website for a new IDT HD audio driver.  Depending on your model, there may be a new version of the IDT driver, BIOS, and other important updates.
    Part One
    Some Setup Checks and on to the Enhancement
    Make sure all basic Sound settings are set to “Default” to start.  
    Portions of this procedure are "not of my invention".  Full credit will be given later in the Post.  This section explains how to increase the amount of sound coming from the onboard speakers.  It also attempts to give you a bit of control over the kind of sound coming from the speakers that you may not have at the present.  Beats-audio is great; frankly, though - it's made for external powered speakers or headphones... what you get from the speakers on the notebook leaves something to be desired.
    A while back I found a very interesting post on the topic of increasing the sound from the onboard speakers.  The post was originally written for the HP Envy15. I believe the post has merit - Part One of this procedure is based on that original post.
    I tested the suggested combined actions – it does work (at least on a healthy system).  The sound quality showed improvement over the standard “out-of-the-box” beats-audio setup and the quantity of volume increased.  In other words, this procedure makes the sound coming from the onboard speakers louder without the use of the Loudness Equalization enhancement setting.
    I would suggest trying this “Enhancement” under the following circumstances:
    Sound Quality is Poor, or the amount of sound from the speakers needs improvement
    Sound is quantity “LOW”*
    Sound is absent AND you believe the absence is NOT due to hardware failure.**  See note on iTunes.
    NOTES:
    * If your LOW sound issue is severe, it may ONLY respond to using the Loudness Equalization enhancement, in which case this procedure is not recommended for your use.  The two are not compatible.  See Part Two.
    ** If there is NO sound on your computer, it’s possible that completing this procedure may not result in any improvement.  See Part Two.
    Sound Controls – iTunes, Media Player
    I would add to the emphasis on checking the volume on one’s iTunes setting.  If iTunes volume is turned down, the notebook’s speakers will respond to that – turn up the volume in iTunes without adjusting the volume in the volume mixer and the sound on the notebook will not increase properly (or will suddenly jump).  It’s a juggling act and one that must be taken into account when the sound is being reset.   Additionally, if you have other audio players on your computer – in addition to those mentioned in the post – be sure to check them for volume controls:  it is important during a sound reset that all the sound players be in sync.  If you miss this, you may not get your sound back. 
    Check for this mismatch in sound volume controls if you do not have sound or if you did have sound and, at some point you turned OFF your sound while watching a moving, a DVD, a something on HDMI controlled audio - and suddenly - you do not have any sound.  Sound controls get tangled up.  Sometimes you just have to unplug it, but you do have to check the controls.
    Sample Rate and bit Depth
    I do not use the suggested Sample Rate and bit depth of 24bit 96000 Hz.  My system cannot tell the difference and defaults everything to 16bits – my recording equipment cannot discern the difference.   My ears lack sample rate sophistication.   I’ve left my dv7t Quad sound, Default Format (sample rate bit depth) at 16bit, 48000 Hz (DVD Quality).  Sounds fine and it’s where most of my crummy recordings are set anyway.  Don’t lose sleep over this one.
    Where’s my Taskbar ICON?
    A couple of HP forum posts have mentioned the loss of the beats audio icon from the Taskbar tray – the icon should restore itself if one can force the IDT driver to reinstall.  Without the IDT driver, beats-audio is not going to work.  Assuming the driver has installed and one can reach the beats-audio panel from the Control Panel, THEN it’s possible that for some weird reason the Taskbar icon didn’t reset.  It might be possible to try and force a reload of the beats panel controller into the Taskbar.  I think this is the file.
    For a 64bit system:     C:\Program Files\IDT\WDM\sttray64.exe

    It took me awhile but I now have the sound level about 3x what it was to start with. Try these tweaks:

    New Window ‘speaker setup’ > Test (should hear sound L/R) > Next >

    NOTE:
    After this DO NOT use the Beats control (Fn + B) or it will reset the tone controls.
    HP dv7(t)
    Taskbar > beats-audio panel
    OR
    Control Panel > Beats Audio Control Panel  
            Listening Experience > Graphic Equalizer > Custom
            -1, +8, +10, +8, +9, +9, +9, +8, +9
    Remember that these are suggestions – start here and re-adjust later as desired.
    LEFT SIDE
    Make sure Beats Audio is CHECKED
            Click the “Music” radio (round) button
            65, 65, 85, 65, 65
    NOTE:  The Left Side settings are somewhat arbitrary.  The “Center” setting is higher – this provides the most sound and should be set higher at least initially for testing, especially if your system has sound issues.
    The next section is partially excerpted from the original Post – Remember: JJ’s post was written for HP Envy15 – please adjust your results accordingly.  Edits have been made for readability.
    Control Panel > Beats Audio Control Panel
    Playback > Speakers and headphones > Arrow above Speaker symbol and Select Small Speakers
    Select Equalization> Select 'custom'>
    Adjustments for this are mainly to boost the signal level in the preamp so we get higher volume while not distorting the sound from the tiny built in speakers.
    My setting values are as follows: left to right;
    -1, +8, +10, +8, +9, +9, +9, +8, +9, +10
    MAKE SURE TO CLICK SAVE WHEN DONE! 
    Note: Do not crank up the Bass (31hz) control or it will overload the speakers which can't reproduce this anyway, you can even turn down more if you have distortion at high volume.
    Check that the slide controls for 'master' and 'speaker symbol' are all the way up.
    This should make a big difference in sound volume and quality, and there is one last way to get louder sound. Depending on what you use to play back your audio you can adjust the program’s sound settings or EQ controls also.
    In iTunes the EQ has a 'preamp' slider which I boost to about +6, this increases the output level while leaving the EQ settings alone (make sure to check the turn EQ on box).
     Windows media player:  you have to raise all EQ levels equally (not too much) to boost without affecting sound quality.
    In general it is not a good idea to use more than one EQ system in an audio signal or you get more distortion, so don't adjust the EQ curves or bass/treble on more than one device.  I chose the Beats / IDT EQ to make the tonal adjustments because it is the audio driver program and preamp that outputs to the speakers, so it should have the best sound quality.
    Any adjustments before the preamp that add distortion will just be amplified, so go easy on adjustments in your play back programs.
    Finally, when you play your audio,
    Sound > Open Volume Mixer >
    Make sure to click the Sound logo in the Taskbar so the slider pops up>
    Click ‘mixer’ then you should see all the sliders for your devices;
     You can independently adjust the levels for the right mix.
    If you open the Beats panel and minimize it then a mixer slider also shows for this and you can dial in the effect of the EQ settings.
    Headphones:
    One last thing; When listening to headphones you will need to increase the bass EQ setting (since headphones can reproduce the low frequencies) in the Beats panel or I just change the drop down selector to the one with a flat curve (beats studio I think) -- the volume for my headphones was not an issue so I defeat the EQ for better sound quality.
    Whew. I Didn't think it was this complicated when I started typing....
    Hope everyone enjoys better sound with this.

    JJB from HP beats-audio / Sound Reset Procedure 
    Part Two
    Loudness Equalization – and the LOW Sound Result
    I was testing the system sound… CD playing in the background: Sting “If on a Winter’s Night” 02 Soul Cake playing through iTunes – standard speakers-headphones (beats-audio coasting along). 
    Sounds -> Playback Devices -> Speakers and Headphones -> Properties -> Enhancements 
    I have rewritten this part three times trying to get it right. Here’s the gist:
    I switched on the “Loudness Equalization” enhancement.  The sound jumped; it was loud and distorted.  I switched the enhancement off – the sound dropped off and didn’t come back.  I turned up the volume (with the slider) and down and up and down – and I was hearing Less and less sound from the speakers:  “Low Sound Syndrome”:  I was hearing what would be expected at setting of 7%.   Well, that sucks.  (Technical term.)
    Based on this experience, I hypothesize that it’s possible to lose one’s sound entirely just by initially adjusting this one enhancement and then losing control over the ensuing ever diminishing returns.  I didn’t continue to test this into a theory.  It’s a hypothesis.  If I had an extra dv7 sitting around, I might sacrifice it on such testing.  I gave up right away and went into recovery mode while I still had some sound.
    Recovery:
    After the Loudness Equalization was turned off,
    Recovery Attempts to recover normal sound levels included:
    Resetting all Sound to Default settings,
    Installing the driver from the webpage (standard load – download, double-click and install), reboot,
    “Hard Reset”. 
    It was finally necessary to force load the IDT HD driver to recover the sound to its normal levels; that is, the driver was Uninstalled and allowed to reinstall at boot.  (“Local” install from the Device Manager also works.)
    Commentary:
    I did not bother with a registry cleaning at this point - it may have made a difference, though it's unlikely since the driver needed to be completely reset by this time.  I advocate registry cleaning!  Bad things happen to good computers because of a dirty registry.  Use your favorite or download CCleaner (free).
    Try a Driver Update:
    You can always check for Driver updates here – If the driver does update - you may be done with this part.  Check the sound and proceed to "Enhancements".
     At the Right-Click > Update Driver Software
    Audio Driver “Uninstall”
    Control Panel -> Device Manager -> Sound, video and game controllers
              Right-Click   IDT High Definition Audio CODEC -> Uninstall
    You have a choice at this point
    If you do not have the means to replace your driver,
    THEN do not delete your driver from the computer
    OR - If you believe the driver is not working at all,
    And / Or you have tried the standard Uninstall/self-install method previously without results,
    AND You have the means to REINSTALL that driver from scratch*
    Then you may delete the driver -
    *Driver Installation From Scratch Requires the following:
    You have your IDT HD driver on your computer as a sp*.exe file, for example, in Downloads
    Reinstall with Boot:
    Shut down the system
    Reboot
    The driver may install itself at login as the system scans for hardware changes
    OR
    Reinstall WITHOUT BOOT - Initiate the scan for hardware changes:
    Right-Click on the IDT driver , >  "Scan for Hardware Changes"
    --> Check your sound at this point.  It's possible that the driver has in reinstalled itself.
    Manual Driver Installation - Comments:
    There are a couple of paths used to get the IDT driver onto your system.  You can download it from your HP Software and Driver website.  You may have been given the path to your IDT driver at the HP ftp softpaq site.  The package is downloaded as a sp*.exe file.   You may download the software as often as you need it.  Make sure you have the package downloaded before you delete your driver.
    Once you have downloaded that package onto your system, the original sp* file will stay intact.  As long as you do not delete it, you can reuse it.  Once you do install the driver onto your system, an installation directory is created in C:\SWSetup, named the same as the sp* file (without the .exe extension). 
    In C:\SWSetup\sp* are all the files necessary to reinstall your driver.  If you install the software from the sp*.exe file in your Downloads folder, the new installation will ask you whether to overwrite the data in the SWSetup/sp* with the contents of the .exe package – do it.  The reinstallation is just unwrapping and redistributing what’s in the .exe file into the same SWSetup/sp folder. 
    If the "Driver Store" is removed, that is, if the driver package is ever removed from C:\SWSetup, you can reinstall from the sp* file as long you you have it in your Downloads folder - it will recreate that SWSetup/sp* folder.
    What about Versions?
    Latest is Usually best.  If you are concerned AND you think you may not be able to get another a copy of an older driver that is in C:\SWSetup\sp*, make a copy of the folder before uninstalling any driver or making any changes.
    Installation from the Original sp* package
    Find the sp* file on your system.  It will be most likely be located in your “Downloads” folder.
    Simple Driver Installation from the 'Saved' installation sp* file:
    Close everything that isn’t needed, browsers, games, windows…
    Right-Click on the installation package (the sp* file), Select 'Run as Administrator' and start the installation
    Answer any questions…and follow the instructions
    or...
    Installation from the Device Manager
    If the driver software is still on the system from a previous installation, it is located in C:\SWSetup
    You can tell the Device Manager to access the package on the system:
    Control Panel > icons > Device Manager > (Highlight) IDT High Definition Audio CODEC >
                          Right-Click > Update Driver Software > Browse my computer for driver software
                          Browse to C:\SWSetup\sp*
                          Be sure the “Include Subfolders” box is CHECKED

    Audio Services Check / Restart
    This section is not strictly part of the "Enhancement" procedure.  It has been included because it is necessary that these settings be correct so that the sound can function properly.  If you are not having sound issues, skip this part...
    Check system Services to make sure that your sound related services are running as they should.
    Restart each service (except as noted):  Right-Click > Restart
    Control Panel -> icon -> Administrative Tools -> Services > bottom of page > Standard (optional - makes it easier to column sizes)
    Sound services must be showing as
    Status = Started
    Startup Type = Automatic
    Sound Services:
    Audio Service
    Multimedia Class Scheduler
    Windows Audio
    Windows Audio Endpoint Builder
    Power (check only)
    RPC (check only)
    That’s it.
    It’s a matter of tweaking the settings to get results.  Do not forget that that Left/Right Speakers setting is turned off in Speakers Configure.  It’s not a big deal (assuming this works), but it’s DIFFERENT and it needs to be kept track of.
    I hope this helps your sound work better!
    Kudos are Earned!

    Nice extensive research on reseting Beats Audio on the HP laptops.
    Just bought the Envy 17t-3000 and I updated all the drivers via HP Support Manager.
    BEFORE the update, the Beats Audio worked well..
    1. Press the dial and the popup box comes up ~3 secs
    2. Volume indicator swirl appeared to show volume level
    AFTER the update, something changed the Beats Audio... had to re-install the latest driver from HP website (even after contacting HP Tech support via chat and email several times)...
    1. Press the dial and the popup box comes up ~10-12 secs now!
    2. Volume indicator swirl DISAPPEARED so volume level indicator is GONE
    Sure the sound works but NOW I do NOT know or remember the volume level whenever I listen to music.
    You can barely tell on the Windows Speaker icon on Icon bar since 2 sound waves indicate at least 50% sound level but that's it!
    I have the following softwares and checked their settings and set them all at 50% and use the Beats Audio dial to control the volume whenever the programs are used:
    1. WinAmp
    2. VLC player
    3. MPC
    4. WMP
    No matter what I try, it appears that the Beats Audio Volume Control Swirl Indicator is GONE! Worse, there's NO Windows volume control indicator unless leave the Volume Mixer open!
    Anyone know how to fix this problem and bring Back the Audio Beats volume indicator??
    Thanks!

  • IMac 10.6.8, Snow Leopard with iTunes 11.0.1. loss of wifi speed when connecting a Bose Sound System via bluetooth

    Hello, I have an iMac 10.6.8, Snow Leopard with iTunes 11.0.1. When connecting my Bose Sound System via bluetooth the wifi downloadspeed goes from snappy to a crawl, disconnecting the bluetooth connection, the downloadspeed goes up again. Don't have this problems with the Sound System when connecting it to my iPad. I like to mention too, that the downloadspeed of my iPad is always better than of my iMac. Are there any experiences concerning this problem? Thank you in advance.

    UPDATE - PROBLEM SOLVED!!!!!!
    You can thank me later - after an hour on the phone, I finally got through to a Senior Engineer.
    Apperently the issues lies with GRID VIEW.
    Open your Itunes, Click on TV SHOWS, then quickly change your view from GRID VIEW (Defaults to this) to List View and Viola!
    We tested it out on the phone just minutes ago, my problem is solved and I suspect if you guys try this yours will be too.

  • Trying to understand the sound system

    Here's my problem. My mic didn't work (neither the front mic nor the line-in in the rear), so after some research and trial and error I found that if I do
    modprobe soundcore
    my mic works on both the jacks
    But here's where my confusion lies. This is the output of lsmod |grep snd before probing explicitly for soundcore
    [inxs ~ ]$ lsmod |grep snd
    snd_hda_codec_analog 78696 1
    snd_hda_intel 22122 1
    snd_hda_codec 77927 2 snd_hda_codec_analog,snd_hda_intel
    snd_hwdep 6325 1 snd_hda_codec
    snd_pcm_oss 38818 0
    snd_pcm 73856 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss
    snd_timer 19416 1 snd_pcm
    snd_page_alloc 7121 2 snd_hda_intel,snd_pcm
    snd_mixer_oss 15275 2 snd_pcm_oss
    snd 57786 8 snd_hda_codec_analog,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss
    soundcore 6146 2 snd
    [inxs ~ ]$
    So as you can see, soundcore's already loaded, so why do I have to explicitly load it again to get the mic to work?
    Once I add soundcore to my MODULES array and reboot, the lsmod output is also the same as above.
    So my question is -- what does the explicit loading of soundcore do, that is not done by auto-loading of that module?

    Oh... since your topic is Trying to understand the sound system, that puts you (and me) inside the whole world's population... chuckle. But I thought I'd pass along a document written by probably "The" main ALSA developer that I totally stumbled across just 3 days ago.
    Go here:
    http://kernel.org/pub/linux/kernel/people/tiwai/docs/
    and download the flavor of your choice of the "HD-Audio" document, or simply view it online. It documents the deepest dive into the current ALSA snd_hda_* layers and issues that I've found to date (but still leaves me wanting).
    Why that document isn't plastered across the interwebs is beyond me. I only get 11 hits when I search for it... such are the secrets of the ALSA world I guess.

  • Connect Macbook PRO house sound system via IPOD adaptor

    I want to connect my Macbook PRO via USB to IPod dock adaptor on whole house sound system w/IPOD adaptor. Any suggestions for adaptors with USB to IPOD-like port?  In other words one end of the cable needs USB (for Mac) and the other needs to look the internal mating part of the IPOD.

    So either get Pandora for iPhone or iPod Touch and dispense with the MBP, or get AirPhones and stream from the MBP to the system via iPod.
    Your primary problem is not finding a cable, but finding a hardware or software device that will make the MPB behave like an iPod, which is quite a different kettle of fish.
    If you're not tied to the dock, then check your system's audio inputs. You could connect your MBP to it, or you could get AirPort Express with AirPlay for w/less streaming.
