Setting up sound system

I currently use an airport express via an amp to play internet sounds to a ceiling speaker system. I now want to get another airport express, amp and speaker system for another area of the house. My question is, must I play one express at a time or can I play the same station over both airport express, amp speaker systems at the same time? Providing the same sounds throughout the house?

PLaying directly from an IOS device to 2 airplay speakers is not possible.
BUt there is a App called Whaale that allows to play to multiple airplay speakers.

  • HT4587 Hi, I want to set up a sound system in a new house using apple equipment. I have few sets of Bose speakers that I would like to utilise, my question is - what do I need to set it up and how do I do it with regards to  AirPlay? Thanks

    Hi, new to the forums and apple tbh.
    Moving into a new house and want to set up a sound system, thought apple would be the way to go as I have iPads, iPhones, iPod touch and nanos. I also have a few sets of Bose speakers which I would like to incorporate. What I am wondering is, what else do I need to buy to do this? Do I need seperate devices to attach to each speaker? Do I need a new router? And how would I configure it?
    Ideally I would like 4 rooms each with their own speakers that could play simultaneously.
    Thanks in advance!!!!

    First, please check out the following Apple Support article for details on setting up an AirPort Express Base Station (AX) for iTunes streaming. Note: You will need a separate AX for each set of speakers that you want to stream to. Also, note that you can stream a single audio file to one or more speakers, but you cannot stream separate audio files to different speakers simultaneously.
    Second, the Bose speakers you mentioned would need to have an audio input jack, either analog or optical digital to receive the stream from the AX. As you know, Bose makes a number of different speaker/home theatre audio options. If your specific model of speakers do, then it's just a matter to use the appropriate audio cable between the audio port of the AX and the speakers.

  • Setting ALSA sound card system wide (rather than just in KDE)

    Hi,
    I've got an HTPC with an ATI Radeon HD 4350 graphics card running Arch x86. It has its own integrated sound card for outputting audio via HDMI, which is detected by ALSA as a separate device. I've managed to set it as the default audio device in KDE 4 (via System Settings). This allows applications such as Amarok and SMPlayer to properly output audio to the HD 4350's integrated sound card, but software such as Flash and MPlayer (from the command line) are still outputting audio to the motherboard's built-in sound card. How can I change this setting on a system-wide level? I've tried running alsaconf as root and adding
    pcm.!default {
    type hw
    card 2
    device 3
    to ~/.asoundrc; I got the card and device numbers from aplay:

  • HT2508 My amp has an USB input but when I attach my mac pro to it, and set the input to the USB setting, no sound comes out. I looked at the system settings, but none of them produce a different outcome. How can I send the music through the USB out to USB

    My amp has an USB input but when I attach my mac pro to it, and set the input to the USB setting, no sound comes out. I looked at the system settings, but none of them produce a different outcome. How can I send the music through the USB out to USB in?

    AFAIK cameras offer their own built-in format utility for inserted SD cards.  You should use that.  Otherwise, refer to the manual that came with your camera to determine precisely how your SD cards need to be formatted to work properly.  Personally, I'd suggest Partition Scheme: MBR, and Filesystem: FAT32.
    Try to limit the number of formats you perform on the SD cards, though, as you're reducing their lifespan.  I believe formatting causes re-writes to a portion of the SD card that has fewer read/write cycles than the rest of the card as a whole.

  • When I plugged in usb Logitech head set, my computer sound system went wacky, making a strange noise

    I am a techno dummy. When I plugged in my logitech headset it didnt seem to work, so i went to the control panel and played around with making it the default recorder. When i unplugged my head set the computer's sound system went wacky making a loud errie sound, until i plugged the headset back in. What did i do wrong? How should i set defaults for recording, playback, and communication ? HELP!

    HP remote solved this problem by down loading High definition audio software. No more problem!

  • Itunes 10 really quiet through airport-sound system set-up

    I installed itunes 10 and am liking some of the new features. However, I have to plug my computer directly into my house sound system now as the new software seems to communicate very VERY quietly with my airport. Not ideal.
    I blame itunes 10 becasaue it was working fine with whatever itunes (9.8.8) I was running before.

    I found this also, iTunes 10 now has separate volume controls for each Airtunes connection (now called Airplay for some reason) You have to click on the speaker icon in the lower right corner of itunes and you can then select the speakers and change their volume independently.

  • With 10.2 I can only use system speaker output for audio, NOT my RME FF400 I used previously. The FF400 works fine with other apps. How can I set this device in FCP 10.2? (it is set in both system preferences and midi)

    With 10.2 I can only use a system (e.g. speaker) output for audio, NOT my RME FF400 I used without any problems previously. The FF400 works fine with other apps (some like TwistedWave) setup in the program, and others (like Spotify) using system preferences & audio midi setup. How can I set the FF400 to be the sound output device in FCP 10.2? N.B. The FF400 is set as sound output device in both system preferences and audio midi setup.

    From the fcp.co forum. See if this does anything for you.

    I have the solution! Well it at least worked for me. This is the response I got from Apple, Can you please try the following steps towards fixing your audio issue, and report back with your results?
    1. Open the application Audio Midi Setup (located in Applications : Utilities)
    2. Select the Output Tab for the current output device
    3. Select the Configure Speakers option
    4. Select the Multichannel tab
    5. Change the setting to Stereo Now mine was set to stereo but the left channel wasn't showing left. re-clicking on stereo reloaded the settings and after clicking apply it worked.

  • 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
    The Original Post and Credits:
    The original procedure and excerpts from that Post follow. Edits have been made to make it easy to read and to follow.  The credits and original link are at the bottom of this page.  My thanks go to JJ and JJ’s HP Envy15.

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

    Control Panel > Sound > Playback > (Highlight) Speakers and Headphones > Configure
    New Window ‘speaker setup’ > Test (should hear sound L/R) > Next >
               UNCHECK ‘Front left and right’ (if checked) > Next > Finish

                 Tone Controls > Bass +1   Treble +3  > Apply
                 Advanced > Default Format > 24 bit 96000Hz > Apply
    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.

    End of Excerpted Post 
    Credit belongs to the original author of the original procedure:
    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!

  • My sound system is not working after my last updates on my imac,what shall i do to get fixed?

    Hello any body who can help me out here?
    My sound system is not working on my imac after the last updates,
    WHAT SHALL I DO FOR????

    apollos211,
    You marked this as solved, so chances are no one else will respond.
    You can try going Applications>utilities>audio MIDI set up, output tab and check to see if built in is selected.
    Also check in system preferences>sound >output and see what is selected there.
    If you look in the headphone port and see a red light (this means it is in digital mode), try taking a set off headphones and plugging them in and out several times also wiggle them around gently. There is a micro switch that sometimes gets stuck.
    Hope this helps, if still no joy try reposting so that more contributers might check it, as once checked as solved it reduces the number of people checking.
    All the best

  • Received a replacement ipod nano in early January . Works well in a sound system but keeps turning off when earphones are used. tried 3 pair but same result. When tried for support comes up as  expires. Says I have to purchase . Why????

    Received an ipod nano replacement in January. It works in a sound system but keeps turning itself of or loosing sound when earphones are used. I have tried several sets os earphones with the same result. When I just tried to seek support my Serial number comes up with warranty expired although the letter says 3 mths warranty. What gives Apple ??? Any one any advice??/

    This is usually an indication that your headphones are not plugged all the way in.  The white plastic part of the headphones should be flush with the Nano and no silver from the plug should still be visible.  The headphone jacks on the new 6G Nanos are a bit tighter than previous generations, so it requires a bit of extra push to get the headphones to pop all the way in.
    Also check make sure the jack is clear of debris such as lint.

  • Airport Express icw wireless modem and B&O sound system

    Hi all,
    I am considering buying the Airport Extreme. Main reasons are:
    1) playing iTunes via the sound system and
    2) wireless connection possibility to external hard disc.
    I will use it in combination with my current wireless modem and B&O sound system.
    From where my internet enters the house it is quite a distance to the sound system location that I can not easily (esthetically acceptable) connect to the sound system.
    My main questions are:
    1) Is Airport Extreme the right system to buy?
    2) Can the Airport Extreme audio output signals be combined through 1 cable for both iTunes and cable radio?
    3) Can I use the Airport Extreme device for playing movies on my television as well?
    I am quite an amature if it comes down to setting up networks and systems, so all (low key) tips are more than welcome. Many thanks in advance!
    Kindest regards,
    Robbie W

    Ummm.....
    The express will not extend your modem, since Apple hasn't shipped its own brand modem for years. You can't extend third party routers.  You can try a few tricks if you have ethernet cables though...

  • Setting up my system

    I recently bought a new 42 inch TV and am looking to add a sound sound system to that.  I have a limited area to work with because of the size and because I am renting so I am unable to do proper wiring.  The current TV has terrible sound and I would like to add surround sound.  I was looking at the rocketfish wireless rear adapter and also some systems with wireless speakers but would like some recommendations
    I already have a blu-ray player (ps3) so I have no need for that.  I also don't really need a DVD player I just need the audio really.  
    I currently have a really old receiver from a sony HTIB from at least 5 years ago that I could use but I currently have no speakers.  
    I am looking to spend below 400 dollars if I can all together.
    I guess my questions would be:
    - Should I look into a system with wireless rear speakers?
    - Should I buy a regular cheap system and just use the rocketfish adapter?
    Thank you in advance. 

    I looked at the manual for that reciever and it has two digital inputs, one optical and the other via an rca cable so you are good on that front. I assume the PS3 has an optical output. Just run the hdmi from the playstation to your tv, and the optical line to your reciever.
    I have a similar reciever to that and it sounds just fine with satalites and a powered subwoofer. It lacks bass with large full range speakers but sounds fine with a powered sub.
    I also like the speakers that Slim suggested. I have some of the older Klipsch satalite speakers and a velodyne subwoofer so its pretty similar to that set up. Either will sound good but if you have the extra 100 I personally would opt for the polks. I have owned both brands and my ears tend to like polk speakers a bit better. They also make a really nice powered sub where as I really don't know much about Klipsch's powered subs.
    I also agree with not going with wireless speakers. I would only go that route if I was just was looking for background sound in a room and not worried about the quality or level of sound or if I absolutely had no other choice. I have not seen very many wireless speakers that really impressed me. Just run the wire, even if you can't hide it. You will still have to run some sort of power cord for the wireless speakers anyway which may limit placement options.
    My opinions anyway,
    Paul

  • 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 ?
