Intel Mac :: Sound Wont Turn Up Or Down Or Mute With Keys?
May 19, 2012
for some reason i turned my apple imac (intel) on today and the sound wont turn up or down or mute with keys and no sound when i plug the headphones in is there something ive done to cause this
My computer seems to be on mute and cannot turn it off. Its gray and does not give me the option neither in the task bar or in system preferences to turn it off. Already tried command PR and nothing.
My sound output preference is set to mute and is highlighted in light gray so that the preference can't be changed. Also, simultaneously, the sound control in the toolbar is gone and is replaced with an eject symbol that responds "SuperDrive F12" when clicked on.
Whenever my MacBook's sound is on mute and the computer wants to play a sound, the speaker has this little click noise.
For example, I mute the sound and go to trash a file. It trashes normally, but at the beginning, the speakers click (almost like they want to play that empty trash noise, but cannot because it is mute).
I was using it for a long time StartupSoundPrefPane11b3 with no problems, but this week I had to erase my hd and restore the disk from time machine. Since then I can't use anymore your program, I checked the boxes "Turn on startup volume control" and "Mute" and turn on the lock. After turn off and on again I get the startup sound. I went to system preferences, and "Startup Sound" program but the "Mute" checkbox is not active anymore. I'm running on a Mid 2007 iMac with 10.7.3 Lion software.
I have been having this issue forever and want to do something about it now. Whenever the sound is mute on my notebook, and there should be sound playing (Ex.: Startup Chime), instead I get a LOUD pop noise. I understand the whole thing with the sound chip powering down to save battery life, but that requires the speakers to be un-muted. In my case, they are mute, and never get un-muted. What do you guys think. Logic Board/Speaker System Replacement?

I have a macbook pro and the audio on it the other day was perfect. Now i cant get it to work. It wont let me un mute it and under system preferences it says that no output devices are available.Â
I watched a video and it was very loud so I went to System Preferences and turned the sound down.But now I can't mute by clicking the F9 button as I normally can. I can mute by going to System Preferences but I don't want to do this.Before I changed the volume in System Preferences, the keyboard keys worked fine for volume adjustment. I could make it quieter, louder or mute.I have tried with checking and not checking the option to display volume on the screen (in System Preferences).

I just bought a 2.4 MBP model a1260. When I got home i noticed the volume keys were not working, and then i noticed none of the function keys were working properly. (example, f12 shows an eject CD symbol). So, the keys are working but not doing the standard functions such as volume and brightness. I have check and unchecked (and restarted) the "use all f1, f2 as standard function keys" to no result.Some other wierd things that seem to be related are:
1. In the SOUND window in SYS PREFS all sound effects are greyed out. Under OUTPUT and INPUT it says no devices found.
2. When i go to the itunes store in itunes and i double click on a song, it wont play. Not only is there no volume, but song wont play. Its the same with my own music from my cds.
3. When i insert a DVD no volume control shows up.
And the last superwierd thing (haha) is that I reloaded leopard and when the computer restarted up after install there was no OSX music that normally plays as the video flys thru the starfield.

Headphones have no audio either.Sorry so long. The computer has no warranty of course.
I'm fairly new to the MAC world and have not found my way around this computer completely. I have seen a commercial of an iMAC sending email and a swishing sound occurred when the email was sent. I wonder how one turns on the sound that indicates the email has been transmitted? And, are there choices of different sounds for this purpose?
I can not deselect mute all computer sounds on my Imac with Lion I went into preference and for output the only thing I can select is headphones is there away to get the built in speakers back on this drop down list?
When I go to turn on my MacBook pro nothing happens. No sound no hd spin no nothing. Last put computer to sleep and had it plugged in charging. Now when plugged in led doesn't turn green or any color just stays off and battery detector on side of laptop does nothing at all.
besides leaving your computer on mute is there a way to turn off the startup noise on a mac? When i come late to class and want to bootup my computer, the apple startup noise draws attention to the fact that i am late and booting up my macbook.
I listen to iiTunes a lot while surfing the web. It's very annoying when I come across a website which has it's own music and it suddenly overlaps the music I'm playing on iTunes. Is there anyway to turn off the sound from all other applications while using iTunes?
My G4 iMac has been making a weird fan sound (a flickering sound, as if there were a piece of paper in it or something). Last night I turned it off and the weird fan continued running. I tried to unplug my mac and plug it back in, but the fan just starts right back up. The computer won't start, I've tried holding the start button but nothing happens. I need my computer today to work.
I have a 3 year old MacBook Pro, so I decided to experiment with Bootcamp. I changed it completly to Windows. Happily it worked, however there doesn't seem to be a way to mute the startup sound. I've searched the internet for answers but the problem is, but all the advice I find tells me either to mute the computer before turning it off (which unfortunately doesn't work), plugging in headphones (also didn't work), or downloading a mac application which I obviously can't as I'm in windows.
Every computer I ever had, the first thing I do is to turn off the startup sound because it is very annoying in a public place and sometimes in a quiet place. I have not been able to find out how to trun it off on my Air. I asked the guys at the stores and they just say you can't. That is really dumb. I turned off my speaker but that is not a practical way because I may not remember to turn it off when I shut down.
I installed the app Hear and i didnt like the sounds.. now all the sound of my mac seems like over eq..and higher bass etc.. i didnt like and and i couldnt turn to back to default settings..even if i remove the app... anyone has any idea how to turn to default sound setting on mac ??
