Sound enabling issue on iMac system.

How to enable sound in imac system ....i am having imac system but sound is not coming on this system. So please suggest me how to resolve the sound enabling issue with my imac system.

Usually a SMU reset will do the trick. You do not say what version of OS X you are running or what type of Mac you have, so only some of the following will apply:

    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.

  • Why is the sound quality on my imac so poor when watching you tube

    I have no problems with sound quality on my Imac(snow leopard 10.68) except when I try to watch you tube.
    Then the sound is really low,muffled and there seems to be some sort of static in the background.
    As far as I know all flash player updates have been installed.
    Cant find anything on google.The problem seems to have started over the past 6 months to a year.....there wasnt a problem before.
    Can anyone help?
    Cheers

    Hi @Gobbling_Monkey ,
    Thank you for visiting the HP Support Forums and Welcome.  I have looked into your issue with the sound not working correctly from your HP ENVY 17j100 Notebook.  The first thing to try is this
    1. Right click the Speaker icon in the bottom right corner by your time.
    2. Click Playback Devices.
    3. Click Speakers.
    4. Click properties.
    5. Click the advanced tab on the Properties window.
    6. Change the Default Format drop-down to the highest quality.
    7. Apply the properties.
    8. Click OK to close the properties window. Restart your Notebook.
    If this does not help try HP support document No Sound from Speakers. It has a number of good troubleshooting steps including using the built-in Windows troubleshooter.
    Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system  that might need updating. If an update is needed this could cause sound issues.
    The Troubleshooting tool in Windows 8 can automatically fix common problems with your computer, such as audio recording. Here is a link to this.
    If you still want to disable or uninstall the Beats follow these instructions. To enable or disable Beats Audio, press the fn key in combination with the b key. The Jack does have influence on the Beats Audio which might need to be turned off.
    Here is a document on how to uninstall software. The bottom link shows you how to disable software.
    Hope this is what you need.
    Thanks.

  • Prboom crashes with SFX sound enabled

    Edit: I installed prboom, timidity++, etc, on a test box, and SFX sound works okay on that machine.
    So apparently I have hardware / configuration issues on my main system.
    When I start prboom normally, with both MIDI and SFX sound enabled, I get the following crash, I_SignalHandler: Exiting on signal: signal 4
    (SFX sounds are the gunshots, explosions, etc.)

    (Commented lines removed.)
    dir /usr/share/timidity/freepats
    source /etc/timidity++/freepats/freepats.cfg

    I've come up empty on Google, this forum, and bugs. So, can anyone help or point me in the right direction? I'm stuck on this one.
    Thanks.

  • 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.

  • HT3231 transfer files to my new iMac system 10.8.3, 9 pin firewire. Apple sold me FireWire 9-6 with a Thunderbolt to FireWire Adapter.  This will not work, do i need a different cable?

    Then it sounds like the FW800 to 400 adapter just gets in the way. You don't have FW800 case? on my MDD G4 I added and used FW800 controller and cases from OWC and Sonnet.

  • I am using iMac OS 10.7.2 with Garageband'11 6.0.4. I can't record sound from  mixer Behringer X1622USB using USB out. when I connect the mixer to iMac via USB  appears USB Audio CODEC on Sound and preferences but no sound from mixer to iMac. Need help.

    I am using iMac OS 10.7.2 with Garageband'11 6.0.4. I can't record sound from  mixer Behringer X1622USB using USB out. when I connect the mixer to iMac via USB  appears USB Audio CODEC on Sound and Preferences but I can't get no sound from mixer to iMac only sound from iMac to mixer. I only can record sound using microphone line in. Please help.

    Eric,
    Thanks for your reply. Realtek audio works only in playback. There is a stereo mix in the mixer but the recording controls are not operable with no sliders in the mixer for any recording option. Slider controls appear to be grayed out. Can't figure out how to enable them. Downloaded newest drivers to no avail.
    The M Audio control panel has no apparent option for recording stereo mix. Adobe ignores the sound from the DVD or CD and shows flatline.
    I'm trying to record the sound from the DVD not rip the track.
    When I go to Audio Driver Setup and select Audition 3.0 windows sound, there is no input device installed.
    I'm thinking of going back to a decent internal Soundblaster card like I have on my 8 year old machine I am replacing.

    Hejssan
    I think you understand english good enough (som ni alla svenskar brukar g?ra (b?ttre ?n vi finskar i alla fall)) so I just give a link to another thread on this forum.
    This issue you're having, is quite common for Creative Audigy carrds (perhaps with OEM models mostly) if you just search this forum.
    You can use those instructions to get some drivers installed to your card. Install drivers first and then all the Creative software you need.
    You need WinRar being installed into your system to get driver package extracted. You can download it from http://www.winrar.de/edownload/winrar.html

  • Can't load Mandrake 9 with onBoard sound enabled.

    Any ideas as to why?
    I can not boot into Mandrake 9 when I have onBoard sound enabled, it always freezes when it tries to load the i810 sound interface system. Yet when I disable it in the bios it loads perfectly.
    I've already installed the nForce system drivers and that didn't help at all. Likely because it didn't know the sound card was there to install for.

    I know your problem.Your not editing the modules.conf and adding these lines.Use vi command to edit.You may have one or more of these lines in your modules.conf and will only need to add the ones you don't have.I only had to add the audio line.
    #vi /etc/modules.conf,press INSERT key, add the following lines,
    alias eth0 mcpeth
    alias sound-slot-1 i810_audio
    alias usb-interface usb-ohci
    press ESC, (Shift) colon, wq and Enter.
    This will save the changes you made.

  • Can I put ALL the sound output from my iMac through Airport?

    Just got Airport Express, and managed to install it very quickly on my existing Belkin network. Just don't forget the $ before your WEP key.
    Does anyone know if its possible to put ALL the sound output from my iMac through to Airport, rather than just iTunes? So internet radio, streaming videos etc?

    Thanks matey - that's just what I was after.
    Not sure if that will also let me put my iMac's system sounds through my HiFi - probably not - but then who in their right mind could possibly want to...?
    (Be nice if you could though)

  • Are there any known compatibility issues with iMac and Google Chrome?

    Does anyone know of any compatibility issues with iMac and Google chrome. A Facebook friend who is a photographer posted recently that Chrome had ruined his iMac. He stead that it ran an update on itself that made safari and chrome unusable - slow running overall. In the end he had to reinstall his OS.
    Is anyone aware of this and should I un-install Chrome off my Mac?
    Thanks,
    S.

    There is nothing official but your post will attract a variety of personal experiences.   I once loaded Chrome and found myself with the dreaded MacKeeper malware, loads of pop ups and conflicts with my system.   Part of the problem is the huge range of add ons you are tempted to  take on, many of which are not as strictly tested as Apple extensions.   I would say, unless you have a specific reason, leave it alone.   The best browser is Firefox and for Macs, Safari is OK.

  • Authorization issue in BI system.

    Hi,
    Having a authorization issue in BI system.
    user trying to run a query in and attempt to drill down by customer, he gets customer details but some of the customers are missing...
    Does the authorization granted in BI system based on customers? Is it a security issue?
    pls help...
    Thanks...

    Hi,
    Please execute the query with your id(developer id who will be having access to all data) first. Check if you are able to see all the customer data. If you are able to see all the data then the user is restricted with some authorizations. ( usually the authorizations are done on sales organization, company codes, plant..etc.. please check how it is in your project...)
    If you are not able to see all the customer data, then check in the infoprovider on which the query is built and do your analysis.
    Check in the roles assigned to the user.
    Hope it helps.

  • Has Apple addressed poor sound quality issues with new 160GB iPod classic?

    I just bought a new 160GB iPod classic, replacing a perfectly good 80GB iPod Video (5.5), thinking that the newer one would be superior to my 3 year old model. I discovered that the sound of the new unit was flat and muddy compared to the older model. I found that the 5th gen iPod video was more "spacial", if that's an appropriate word to use; the bass was more present and more clearly defined, as was the rest of the sonic spectrum. I searched several forums to research this issue and while there were numerous references to this issue, all of the posts I found referred to the original iPod classics (80GB and 160GB) and not the later 120GB classics nor the new 160GB classics like the one I bought. Has Apple done anything to address this issue since the first classics were released or are the new ones still suffering from the same sound quality issues as the original classics?

    Based on your observations here, they apparently have not changed the sound quality since the original 160GB classic. I noticed a clear narrowing of the sound stage (ambiance) between the 5.5G 80Gb and my 6G 160GB. You're describing the same characteristic. I don't own the newest 160GB version and came here today to see if it might have improved the sound quality back to the 5.5 spaciousness. Note that the 5.5G has a higher signal to noise ratio than the 6G, making it difficult for me to enjoy it through efficient balanced armature in ear monitors like the Shure SE530s or Ulimate Ears Triple.Fi 10s.

  • Sound input issues.  Not related to Soundflower or Balance issues

    So.  With the sound flower issues fixed.  And my balance knobs in place for my stereo speakers.  I have opened up a new song I have been writing.  Again the AVIGrandpiano app was the track I was recording on.  Like my previous post from last week the input on the new music was very faint and not at all matching the input of the previous recorded music.  (See Screenshot on earlier posts) 
    I am at a loss as to where to begin to fix this.
