Sound problems: volume always muted.

iMac 20" dual core
Tiger 10.4.8
The com.apple.soundpref.plist file has disappeared from the Macintosh HD Library. The volume now is muted. When it's at 50% I can barely hear anything from the speakers. I've been told I need to do an Archive and Reinstall, but I want another solution! I have the soundpref file in my User Library, but copying it to the HD Library doesn't do anything. Restarting doesn't do anything. I created a new account and it was also missing the file. I've read that maybe the computer thinks my headphones (which I've used recently [though I used them before with no problems]) are still plugged in, but in System Prefs, the Sound Output Devise is the internal speakers . . .
Hayulp!
Thanks.

Thanks Reggie. Nothing happened when I tried that this morning and so I went to the Apple Store and they couldn't find anything wrong with the software and it was so loud in there they couldn't be sure there was a hardware problem either.
They did confirm two important things:
- There will not be a com.apple.soundpref.pslist file in the HD Library; this file is only in the User library.
- There are no "headphone" settings when headphones are plugged into the jack: it's analog and can't even "look" for any information that would tell it to dampen the sound.
The remaining question: why doesn't the soundpref file renew after being deleted? Why does it have the same creation date as the day I installed the OS (when I bought the computer)?
Thanks for your time. Happy New Gregorian Year.

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.

A30 sound problem

have tried all drivers from toshiba web sites, uk, canada, europe etc but cannot get sound to work on my satellite a30, model no PSA33E 7C3F3 EN, fresh install of xp had 4 drivers missing, ati video, smbus, modem and sound, only drivers from canada site worked for video smbus and modem, xp states sound working properly but no sound from speakers or headphone socket and have checked all volume levels (on full nothing muted), any ideas ???

Hi,
Just to inform you that my problem was solved by itself :)
I've reformatted my laptop and installed the original XP Pro SP2 again by following the instructions.
Sound problem was solved automatically, no chipset utility installation required..
The sound problem was probably caused due to missing Microsoft KB835221 update for SP1, and KB888111 for SP2, which then was solved with the original latest XP..
Rgrds..

Sound problems with CNBC and E4 with TV @nywhere Master

Got the TV @nywhere Master card, had no problems with tuning in the cable stations picked up all the channels, but E4 and CNBC have no sound just a anoying clicking sound. Have updated the drivers and software, tried the card with Windows 2000 SP4, and XP pro SP1, tried both internal & external audio connections, nothing makes a difference. Anyone got any idea's?

I bought and installed a TV@nywhere Master yesterday (18June03) and no sound problems at all. The Radio volume control definitely controls the line in volume, but check that the mixer Volume Control is not being muted. My Sound in via on-board sound 6 channel Realtek ACL650.
I have been generally very pleased with the results but have yet to get the remote to do anything, I have WinXP SP1 with all updates installed. Not sure if it is my System set-up or faulty remote but it a minor concern for me.
I would suggest that you take a look at VirtualVCR (freeware) for your capturing if you want more that Mpeg files. It works very well for me and allows me to capture using the frame size and codec of my choosing

My iPad will not play sounds on certain applications. ie: if I click on a video from FB sound will not play. If I go to YouTube and play the same video sound will play. Also certain games will no longer play sounds. They always played sounds but now won't

My iPad will not play sounds on certain applications. ie: if I click on a video from FB sound will not play. If I go to YouTube and play the same video sound will play. Also certain games will no longer play sounds. They always played sounds but now won't now. I just went to my churches web site to watch live service and again no sound. I grabbed my dads iPad and the sound works fine.

If you lose sounds for keyboard clicks, games or other apps, email notifications and other notifications, system sounds may have been muted.
System sounds can be muted and controlled two different ways. The screen lock rotation can be controlled in the same manner as well.
Settings>General>Use Side Switch to: Mute System sounds. If this option is selected, the switch on the side of the iPad above the volume rocker will mute system sounds.
If you choose Lock Screen Rotation, then the switch locks the screen. If the screen is locked, you will see a lock icon in the upper right corner next to the battery indicator gauge.
If you have the side switch set to lock screen rotation then the system sound control is in the task bar. Double tap the home button and in the task bar at the bottom, swipe all the way to the right. The speaker icon is all the way to the left. Tap on it and system sounds will return.
If you have the side switch set to mute system sounds, then the screen lock rotation can be accessed via the task bar in the same manner as described above.

MSI P6N SLI sound problem under windows 7

Hi all!
I have an MSI P6N SLI mainboard and I have installed win7 ultimate x64 to get a look on that OS. Everything works fine expect one thing: I have no sound. I tried to install manually the realtek sound driver but no changes. When I check the Volume Control Options then neither the Speakers nor the Realtek Digital Output checked (but the speaker is plugged in).
However I have sound under Linux.
Could someone help me? (and sorry if I have missed the topic which resolves this problem if there is any)

Hi everyone,
hope it's ok to refresh this thread - I did not want to open up a new one, because this one matches my problem perfectly - but my speakers are plugged-in the right way
I'm running Win7 64 on the MSI P6N SLI (not v2 no Platinum) and am unable to install the sounddriver (well not correct - I did install the driver). The upgrade advisor said all green (under Win XP 32) and the MSI-Driver-Page propagates Win7 32/64 is supported for the SoundCard of my Board.
The driver installs just fine, but the device won't come out of "I have a problem"-state - always telling me "The drivers for this device are not installed. (Code 28)" (I event tried installing the driver manually with pointing the win-hardware-setup-routine to the driver-directory) - still no use - I removed and rebootet serveral times...
Hope anybody has a solution for this problem (I'm taking the posts above as a "this has to work"-basis so i'm not ready to give up and go out there and buy a new soundcard )
Thanks in advance for any hint.

Volume keeps muting

my volume keeps muting by itself..yes i checked the button on the side...its done it a few times..i even check setting and it shows the volume up all the way...turning the phone off and back on seems to fix it..but then it happens again...what gives?

I have the same problem - I've toggled the ring/mute button, reset the volume in General Settings, and sworn at my phone a lot when I've slept in (alarms are supposed to still sound even if the ring button is on mute). The phone vibrates, but I also miss a lot of calls and the mild vibration of the phone on the end table was not enough to wake me up this morning.

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

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...

I have a number of apps on my Ipad2 that no longer have sound. I have checked setting on my ipad and the settings on the apps that have a settings and the sound and volume are ok. Do I have a virus in some apps?

I have a number of apps on my ipad2 tha no longer have sound. I have checked the ipad settings and the apps that have settings and all sound and volume are ok. Do I have a virus? Pandora sound is ok. It seems mostly to be games...angry birds, tap tap, and educational games for little ones. Any suggestions?

There aren't any viruses for iOS devices. Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.

Volume is muted when Mac Mini starts up.

Hi all,
I currently use my previous generation Mac Mini (Core 2 Duo 2.0) in my media center.
Whenever I restart the machine, the volume is muted when it starts back up.. I then have to go in and manually unmute it.
Because this is part of the entertainment center, it's kind of a pain.
Anyone have any idea what is set that would be causing it to do this?
Thanks for any info!

Hi Steve,
Can you use a keyboard to audio volume control? Sounds like something is overriding the system somewhere.

The sound effects volume is all the way down. It pops on for a second, then disappears. I can't find it in settings. How do I get the sound back?

Sound Problems on iPad: how to fix, easy [video]

Hi dear iPad user,
Most people will, eventually, have sound problems: the cause can be complex as a 'miss-behaved' app that messes the sound engine or as simple as the iPad being forgotten on Mute/Volume Down.
I used to help family and friends to fix their iPads' sound problems by sending them 'text' instruction steps... lots of times they ended up calling me on the phone...
So I made a video (short: 1m40s):
https://www.youtube.com/watch?v=FjBP-Ncj_fE
It shows:
how to unmute the sound (even if the side-switch locks the rotation of the screen)
how to put volume up
how to close all the apps (in the case there is an App messing with the sound system)
how to reboot the iPad (ultimatelly fixes hard cases of messed sound system)
What it won't fix: if you have a hardware problem...
If you do all the steps and you get NO SOUND AT ALL, please, try also checking if you car listen sounds using a HEADPHONE (you know are working conditions). If you can listen to sounds in the headphone but no sound at all in the iPad's built in speaker, well, there might be a hardware problem and you should look for help on an Apple Retail Store or other official technical support available at your location.
Hope this helps!
Everson.

UPDATE: fixing iPad Sound after iOS 7
http://youtu.be/SDf1LDcE95Q
(1min 36sec)
It covers the basics:
checking side-switch / mute / "Control Center"
volume all up
...and also the worst cases:
closing all apps (for rare cases when a single app might render the sound system instable)
rebooting the iPad
So, don't get desparete: try the things in the video.
There are people who reported having forgotten an audio-bluetooth connection activated with a turned-off sound-system or speakers... or forgot Air-Play turned on... so be sure you disengage bluetooth and/or airplay.
On the 'hardware side', dirty dock connector (30 pin) can make the iPad 'think' it is connected to external audio - if so, cleaning it with a dry toothbrush can fix. Also, moisture in the headphones connector can make the iPad switch to 'headphones' even without headphones connected, making it silent: check if you can hear things with headphones plugged in - if so, try gently inserting and removing headphones a few times and check if you get sound back to iPad's speakers alone.
Good luck to everybody! Audio problems are quite common - fontunately they are easy to fix.

After reformatting my laptop and re installing xp pro everything works but my sound,,, before anyone suggesting I should renew my sound drivers or even update my BIOS let me mention that I have already taken those stept, the Mic works but I have no sound coming out of the laptop.....
Any Ideas????

Hi Nick,
Sorry for the long delay I only just noticed your post. Easily done if you post in the middle of another thread.
To diagnose your sound problem the best approach is to systematically check (and isolate) each possible problem area until the culprit is found. For sound problems follow the sequence :-
1. Check Hardware. If you have a manual control check that it is turned fully on (this may be a wheel or knob somewhere on your notebook). There is no point carrying on if this is turned down/off.
2. Check Software. This is where the fun begins.
2.1 Check the sound properties (available from Control Panel) and make sure that the MUTE box is not ticked.
2.2 Check the individual volume levels shown on the sound properties box. Set them all to maximum.
2.3 Select Device Manager (from Control Panel) and check the entry for Sound/audio devices. Select your sound device and click the 'troubleshooting' option. Follow the on-screen checks.
2.4 If you still have no sound deinstall the sound device (from ADD/REMOVE hardware) and reboot. The system should detect the sound device and re-install it)
2.5 Finally download and reinstall the correct device drivers for your sound devive from the Toshiba web-site.
2.6 If you still have no sound after all of the above then I would recommend a complete re-install of your system from the Toshiba Recovery CDs. and if that does not correct the problem then you will need to take it to a Service Agent for them to sort it out.
HTH
