IMac (Intel) :: Sound Sometimes Doesn't Work Or Will Cut Off
Jun 25, 2014
Every once in a while my sound just either stops working, or won't come on when I begin to play something. I try moving the volume up & down, turning things on & off, plugging and unplugging headphones, etc, and there seems to be no consistent method to get it back to functioning... What could be going on to cause this?

I have an Intel-based iMac which I just upgraded two days ago from Snow Leopard to Lion (10.7.4). I did an upgrade-in-place (as opposed to a fresh install) and did a software update after the installation completed. I have my computer scheduled to wake up each morning at 6 a.m. When it wakes up, the sound doesn't work unless I reboot the computer. If I open up iTunes and try to play music, there is no sound (unless I reboot). The song progress meter at the top of iTunes won't even move when I hit the play button. When I open the Sound preference and click the Output tab, I do see the Headphone port and the output volume is set all the way up.

I have an iMac G3 keyboard that I'm trying to use with my MacBook, it works PERFECT, except when I press caps lock it just stops working. Also, when I first plug it in the Caps Lock light flashes green for just a split second. Is there any chance of getting hold of some software that would help?

The volume is muted, but I can't un-mute it because I am unable to click on any of the sound options because they are all "grayed out". The little box next to mute is checked and I cannot un-check it because it's grayed out. Nothing works when I plug in headphones or speakers or anything, and there is no red light glowing where you plug the headphones or speakers in.

I feel something might be up with my 4850. I get some weird rendering in WoW (in OSX) and it doesn't seem to preform very well in COD4 (in Windows). Seems like these issues recently started.
Anyone else have an issue like this? Seems like when I first started using this system I had no problems. I have installed latest drivers.
I have SMCFan going on a higher speed to reduce heating. Done everything I can think of and stilll having issues. Am I missing anything?
I'd like to find some sort of program (OSX prefer) to do a stress test on the graphics card if there is one if there is one.

I'm a relatively new Mac user so I'm not sure if it's user ignorance or something is wrong with my computer but nothing happens when I insert a cd into the drive. Nothing shows up in iTunes, Finder, or on my desktop. Shouldn't I see an audio CD in iTunes? And if I put a blank DVD into the drive, shouldn't it show up in Finder so I can burn files to it?

After several attempts my firewire would not mount on the iMac desktop. After reading the forum, so I reset the PRAM and the SMC.
NOW, after rebooting the iMac after 3 or 5 minutes the external disk connect with a firewire 400 appear on the desktop with a spcial mention from my iMac " Could not repair the external disk !?
Even though the disc is NEW and formated on the same machine two hours early!

Have a new iMac (last years) with 10.5 on it. My email worked normal before I transferred Applications, files & etc from my old G4 with 10.4.
Now I can only get to my email through through my Earthlink home page by logging in & etc. (a real pain just to check my email!)
If I try to use the email icon on the iMac dock I get the email line at the top of the screen , but email page does not open. I have to go to menu and click on "In" and the page opens up but does not download any email. Will not send from this location either. When I try to quit email it will not close. I have to force quit it.
Earthlink said to trash their "Total Access" as it won't work with 10.5. So when the iMac was working ok before the transfer of files I must have been using Apples Mail application. How do I get it working again? I looked all over Mail Help and Apple help and nothing seems to work. Safari works ok.

I bought a used iMac from a seller on ebay. Everything works perfect, iSight camera is excellent. I tried recording a video and it worked, when I played it back it had no sound at all. I already tried going to system preferences and changing it to built-in microphone. I also reset the PRAM. I don't know what else to do!!
It has the version 10.6.8 installed, I don't know if that has anything to do with the mic not working.

The only way can restart my Intel iMac27" desktop is to reach around at the back bottom left of the computer and hold the button down for about 6 seconds, If I don[t I just get the spinning wheel. After I restart manyally I get the gray apple logo and the same spinning wheel - and then it startsup fine. Reinstalled software several times.

Trying to add jump audio upgrade to my imac sound. The bass jump has great reviews but mostly for macbooks. They did not have one set up in Apple store so im on here to see what others might think of this product. My other choice as recommended by apple employee was the Bose companion 2. Only thing with this is they work from headphone in jack so i will have to keep them on all the time even when the imac speakers would have been fine for simple computing.

I own the latest version of an iMac, and my sound refuses to work.However, when I start the computer up, it makes the long noise just before the gray pages with the dark gray apple comes up. But other than that, I have zero sound on the computer. I can't play my iTunes, nor can I watch youtube videos. Zip. Nada. No sound.

Ok so my iMac g3 has a left speaker that doesn't work. The right one works fine and when I turn the volume up the left speaker kind of buzzes. Is it even worth replacing the internal speaker? (IIRC it looks pretty difficult)

This is an odd one, My imac can't seem to recognize my airport card.The airport utility can't recognize any device. The network diagnostics recognize the internet with the green lights but the airport lights are red... My browsers are connecting to the internet and I am receiving email. The airport icon in the menu is blank and when I open the menu it says "Airport:Not configured"
