Mac Sound Problem

Ok so all of a sudden a problem turned up on my mac. I can hear audio from iTunes but from nothing else... Garageband, Quicktime, Firefox, Safari... nope. I can hear system sounds and anything in iTunes works perfectly. Also apps like Hear from Joesoft have no effect.
Newbie, Thanks for your help!

You should try to use the guest account and see if this issue occurs also in the other account. If it does then it is the entire system. If it doesn't then that means its only your current account. If its only your current account then the easiest solution is to transfer all your files to the other account and delete your current account. If its both accounts then try an archive and install. That's to install the OS again. If that doesn't work then a trip to the Apple Store is necessary because that means its mostly a hardware issue. Try those our first. Reply if you need details on any of the steps.
Also, can you back trace as what you did out of the ordinary right before you notice this happening if there's any.

  • More Mac Sound Problems

    I have lost sound on my Mac. All of it except for the startup tone. That means iTunes, DVDs, and even alerts. I have tried zapping the PRAM as suggested elsewhere on this forum but I am not sure that is happening. I shut down the computer, wait ten seconds or so, startup, and get to the Option-Command-P-R keys before the gray screen, but I never hear a second tone. The computer just loads as usual. I've tried numerous times and, of course, I still do not have sound. On my old MDD Mac G4, there was a little button on the motherboard that you could push to achieve the same end. I tried locating on the MacPro and "think" I found it in the far top, right hand corner of the machine. Anyway, pressing it causes the computer to restart. I have pressed it and then scrambled to get to the Option-Command-P-R keys before the gray screen but still get the same results - in other words, no results. Any ideas?

    Hold the PRAM keys down BEFORE you restart and keep them down until after the second tone. This requires long fingers and strategy, or a second person!

  • Desperately need some help!! iTunes/Quicktime/iChat/Sound problems....

    So, yesterday, I was online, on google video, and when I pressed play on the video, there was no sound, but the video worked...the same was true on every video site i checked. My computer volume was at max, and I even tested the speakers to make sure they were on, and they indeed were.
    I thought that was odd...but then the problems really started.....
    After that, I clicked on my iChat icon. It bounced once, and did not open. The same thing happened when I clicked on iTunes. 1 bounce, and then nothing. I checked to make sure all of my iTunes mp3 files were on my computer....they indeed are all still here, bit nothing I can do opens iTunes. I've run disc utilities, and disc repair...according to that, everything is peachy-keen on my computer.....but iChat and iTunes STILL will not open, and there is still no sound on anything.
    Now, i'm leaning towards the archive and install option....or even just backing up what I want to save, wiping the drive, and starting from scratch.....but i'd really like to not have that happen.
    (and, as a side question, if all I want to save are images, several documents, and many mp3 files, would everything be okay if I just backed them up on an external drive, and then loaded them back on to my computer after reinstalling OS X?)
    Sorry about the length of this, but I am at my wit's end, and I have no idea what to do.

    by third-party, do you mean things I installed that are not manufactured by mac? If that is the case, I have microsoft office, Smart Music, Flip4mac, and Senuti.
    I got rid of Flip4Mac to see if that affected my sound problems, but it did not. So, as of now, my problem remains the same...

  • Any resolution to the sound problem?

    I have been having the same sound problem with my Mid 2010 Mac Pro tower ever since I got it.  I have been in touch with Apple and have been told that they are familiar with the problem, but that they are still working on a fix.  The problem is that I have external speakers, and every time I shut down and then start up again, I have to go to preferences and physically change the sound output to go to the speakers.  I have also been tole that the Mac is supposed to sense the external speakers and go directly to them.
    Is there anybody else out there with this problem, and has been able to resolve it?
    Thank you.

    I have a 2010 Mac Pro and use the stereo line out jack in the back of my machine for my speakers with no problem.  I don't recall any problems setting it up.  But check the Audio MIDI Setup (in your utilities folder) to see if you can set it from there (should be able to).  Not sure why the preference wouldn't stick.  And I don't believe there is automatic detection of an attached sound output device where the sound preference switches to that (unless maybe the front jack which I never use).

  • USB Sound Problem

    I'm having a problem with my Bose USB sound system that has just recently developed. The system is plugged directly into the back of my Mac Pro desktop so it's not going through any hubs or secondary systems. When I first start my computer the sound works just fine. But after about 10 to 15 minutes of use the sound stops completely - as if the sounds have been turned off. If I boot into Windows 7 using Boot Camp, the sound system there works just fine with no problems at all, so I do not believe this issue is hardware related but is something associated with OS X.
    This all started recently after installing Tinker Tool and then realizing that their latest version is not compatible with Snow Leopard. I followed their directions and told Tinker Tool to restore the previous settings and then I removed it from my system. Now, I'm having this USB sound problem. I think it's highly probable to be the cause of my problem.
    Is there anyway to reinstall the USB drivers in OS X without reinstalling the entire OS? Or, is there something else I can try to restore the USB function to Snow Leopard? Many thanks for any tips or suggestions.

    They are plug and play.
    I did try unplugging all of the USB devices and then powered off the computer and unplugged it for about 5 minutes as I heard that that sometimes solves USB problems. However, upon reconnecting the problem returned. All other USB devices seem to be working normally - it's only the Bose sound system. I tried plugging it into a different USB port in the back of the computer but the problem continued after about 10 minutes. Therefore, I am convinced this is not hardware related.
    At this point I am thinking I need to reinstall OS X Snow Leopard to undo whatever Tinker Tool damaged. Is it possible to just replace the USB drivers in OS X without reinstalling everything?

  • Pismo Sound Problems after Sleep in Tiger

    Hi all. New to the forums and returning to Macs after years of cursing Bill Gates. Picked up a Powerbook Pismo from a friend and have been having some fun with it, but I have one problem I can't solve. I replaced the hard drive (saved the old one) and installed Tiger and 1GB of memory on the machine. All seemed well until I noticed that the sound would not work sometimes after sleeping. The sound will usually return with a reboot, but sometimes I'll have to actually turn the machine off, and clear the PRAM to get the sound to come back. Sometimes, the volume and screen controls will both not work at all (pop up doesn't even appear when the keys are pressed), sometimes it's just that the sound doesn't work, but everything looks right on the screen. I've also had the sound and screen buttons not work only to have pop ups suddenly appear and the adjustments happen several minutes after I pressed the keys. So far I've tried:
    Clearing the PRAM
    Checked the Pram Battery (ok)
    Reinstalled Tiger (Still loses sound)
    Downgraded to 10.3 (problem persists, and seems worse)
    In system information on Tiger it says "there was an error when retrieving that information" when you click on the sound hardware.
    The machine is a 500mhz Pismo with a 48gig drive and 1 gig of Memory (133mhz, would that cause this sort of problem?)
    I have not tried going back to OS9 to see if the disappearing sound resolves as I don't currently have an OS9 disk.
    This sure seems like a software problem, but I'm starting to wonder. I really like this machine and want to get it to work! Help!

    Maxstang, welcome to Apple Discussions.
    Did you repair permissions after you installed Tiger? Have you updated Tiger to 10.4.11?
    Here's the Sound troubleshooting info in the Pismo Service Manual.
    No sound from speaker(s)
    1. Verify mute mode is not enabled (F6 on the keyboard).
    2. Check the volume setting in the Sound control panel.
    3. Verify no external speakers or headphones are plugged in.
    4. Reset PRAM.
    5. Make sure speaker cable is plugged into sound card.
    6. Replace sound card.
    7. Replace speakers (part of the top case).
    8. Replace I/O logic board
    Startup sound is heard, then no sound from speaker(s)
    1. Remove sound preferences from System Folder, reset PRAM,
    then restart.
    2. Perform clean installation of system software.
    Had the Pismo previously had OS X installed. There's a firmware update (Boot ROM version 4.1.8) that should be installed prior to installing OS X. However, when I got my Pismo with Tiger installed, the firmware was not updated (have since updated). However, I don't think this could be the cause of your problem, since I had no sound problems when the update was not installed.
    The PC133 RAM (which runs at 100MHz) should not be the problem. I have PC133 RAM in my Pismo.
    Since you replaced the HD, could you have disturbed the connection to the Sound Card. The Sound Card is located to the upper-right of the HD. Here's a helpful laptop site.

  • Massive sound problems in Yosemite

    Hi,
    I have been experiencing massive sound problems with Yosemite. It basically effects everything except the sound control in the control centre.
    What happens:
    I can't control the sound volume anymore. Key board sound control does not respond (sound symbol is struck out), sound bar in menu bar in greyed out.
    If sound symbols are not greyed out, the sound will stay on the level it currently is. Neither key board nor menu bar icon can change the volume.
    When it happens:
    When I plug/un-plug headphones.
    When I use iTunes. iTunes will even stop playback... the only chance to get iTunes back to normal is restarting the app.
    When I use Skype.
    Occasionally on any incident... there is no app in particular linked to this.
    What I do to get around it:
    Restarting the mac... this will help until I sent my Mac to sleep or do any of the things above.
    Accessing sound control via the control centre (which is work around, yet very annoying).
    Killing sound via terminal does not do anything.
    Btw. there is only one thing listed in the sound input/output menu.
    This problem is very annoying and occurs several times daily, especially since I work a lot with sound and music. I know this an weary argument, but considering what I paid for this machine ... bla bla bla... I need a fix.
    Thanks for any advice.
    Andy

    Hi,
    Thanks for your reply.
    Yes, I have. It works pretty much like any re-start does. As soon I use headphones or send my Mac to sleep, it goes back to unresponsive sound control.
    Edit: Just tried it again and it didn't do anything. Key board sound control is still greyed out...
    Any other suggestions?

  • Sound problem with macbook pro! help please

    hi guys!!
    my mac sound is not working also the headphones however if i plug the hdmi cable it works on my tv !!!!! I think it is a hardware problem!!
    what do you think guys !!!!

    Hi a,
    Have you checked the settings in System Preferences > Sound?
    There is a switch inside the audio jack that may be stuck. Try gently inserting an audio plug, gently wiggling it, and then removing the audio plug.

  • Imac G5 isight sound problems.It's muted!!!

    Hello to everyone.
    Since I installed Leopard I've been having an extremely annoying sound problem. It has happened 4 times so far. When I switched on my mac and tried to listen to some music, the sound was not working at all! I went to system preferences/hardware/sound and all the topics were grey! It was like I didn't have any sound! After repairing the permissions, verified disk and repaired disk with the Leopard DVD everything worked ok, but after a few days the same think happened again and again and again... Please help me because it's VEEEERYYYY annoying to waste my time with these thinks that were suppose to work in the first place.
    Thank you in advance.

  • Output Sound Problem

    Has anyone noticed that output sound on the itunes is distorted and after opening and playing the same file in QuickTime that the problem is gone?
    I am using iTunes to open and play a sound file, say an imported CD song, and the sound is distorted.
    Checking the preferences option to perform a Sound Check helps but does not completely solve the problem. After opening Quicktime and opening the same file, the output sound is fine, in both applications?
    It seems that all was well before my update of the applications and the Firmware. Should I be suspicious of that as the culprit or is this some other symtom of impending doom?
    The sound problem is on internal speakers, earbuds, or a set of sennheiser headphones.
    itunes 7.0 updated a few days ago
    QuickTime 7.1.3 updated recently

    I might have the same problem. Playing audio occasionally becomes very scratchy, to the point that I have to stop listening. It usually lasts a few minutes. It's maddening.
    It happens via the internal speakers or through headphones.
    Occurrence isn't very consistent. I notice it most in iTunes (v7), but that's probably only because I play most audio in iTunes. I've had it happen now when playing video in VLC, too. It seems to only happen after playing audio continuously for at least 10 minutes. I haven't been able to reproduce it at will, so I haven't bothered taking it to my local Genius bar yet (at least not for this problem).

  • Seeking pointers for coding with Mac::Sound or other Perl packages

    Greetings and best wishes.
    I am working on an experimental/recreational VoIP app using Net::SIP. All of the SIP stuff is easy and I am sending/receiving calls to/from my VoIP provider, no problem. I am to the point where I want to hook in live input from the system mic and/or play output directly to the speaker. I am i need of some pointers to get started. Currently I am using VLC to speaker the output and have no Mic input.
    I have Mac::Sound (and the full Mac::Carbon) loaded, but I seem to be having trouble tracking down simple doc and examples. I can play an example sound file (Scream.rsrc) using SndPlay(0, $snd, 0), but I don't know the format of the resource file. And really, I don't want to play files, I want to stream my output (ULAW or decoded ULAW) to the speaker, and send the live Mic input to the call. Can anyone help me with some pointers to get started?
    Ultimately, I will want to use a USB headset rather than the onboard mic and speaker.
    Thanks.

    Thanks for the advice about the obsolete status of Carbon (and perl Mac::Carbon). However I don't see any perl packages to interface to Core Audio. As I am experimenting, and as Carbon seems to work great on my 10.4.11 iMac, here is what I have done. To play an 8000 khz Ulaw clip held in some scalar, the following simple fragment will suffice:
    use Mac::Memory;
    use Mac::Sound;
    my $ULAWCOMPHDRSIZE = 84;
    my $RATE8KHZ = 8000;
    my $MONO = 1;
    my $BITS8PERSAMPLE = 8;
    my $snd = <some ulaw encoded sound data>;
    $hand = NewHandle($ULAWCOMPHDRSIZE);#setup won't grow handle size so don't $h = new Handle
    Mac::Sound::SetupSndHeader($hand, $MONO, $RATE8KHZ, $BITS8PERSAMPLE,
    kULawCompression, kMiddleC, length($snd));
    $hand->append($snd); # the Handle methods all take care of size and resize for you
    SndPlay($chan, $hand, 0); # sync play
    You can async the play ( SndPlay($chan, $hand, 1) ) just fine, but unfortunately, the callback functionality is not supported. But as I am streaming well timed RTP buffers, I can handle the async complications in other ways.
    I haven't started on recording from the MIC yet, but I expect it can be accomplished similarly.
    Thanks.

    What sound problem - no sound on anything, no sound on some apps ?
    Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.
    Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

  • Applet in Apple Mac OSX problem

    Hi all,
    have developing an applet long while using WinXP platform, everthing seem ok, but when i try over Apple Mac OSX, i has a loading problem saying that init failed to load ArrayList as error message said:
    ArrayIndexOutOfBound, 0...
    but when i debug print out the ArrayList content and its length, i'm sure that this ArrayList is NOT NULL and its length is NOT ZERO either. what is happening here? oh, ya, this only happen in Safari, in FireFox for Mac no problem, even Camino also pass the test, why? anyone have idea about this? because i'm new to Apple Mac.
    also, there is another question whereby, when i use FireFox for Mac to load the applet, the applet load seem no problem but it just can't display properly. what i mean is that in Windows platform (IE6), this applet show entire applet successfully, but when i try it in Mac, it show only a part of applet without any error, but when i try to refresh the page, applet is now successfully show, why?
    lastly, when a button of an applet being click and this will bring a new window with some parameters value, its work on IE in Windows platform, why it won't work for FireFox or Safari for Mac? i see prompt out saying is security problem, is there any workout of this? thanks. to summary out of junk above:
    _______________________________FireFox_____Safari_____IE
    _______________________________Win | Mac_____Mac____Win
    1. load applet for 1st time___________OK_|_NO_____FAIL____OK
    2. refresh applet after 1st load failed___OK_|_OK_____FAIL____OK
    3. when applet button click (security)___OK_|_NO_____-_______OK
    p/s: all above test was using same applet with same parameter and value.
    below is the sample i capture from Apple Mac just now:

    but when i debug print out the ArrayList content and
    its length, i'm sure that this ArrayList is NOT NULL
    and its length is NOT ZERO either. You can still get an out of bounds exception with those conditions. The list could exist, its length could be N, but you're trying to dereference position N + 5, for example.
    try it in Mac, it show only a part of applet without
    any error, but when i try to refresh the page, applet
    is now successfully show, why?My guess is that you're not calling repaint() when you should, but that's just a guess.
    lastly, when a button of an applet being click and

    above:Often you can sign applets so they can do things that unsigned applets aren't allowed to do.
    Maybe you're making some kind of security mistake that Firefox and Safari are (properly) catching but IE isn't. In any event, post the error message.
