Sound just stopped working

[justforfun]

Not sure why, but all of a sudden have no sound effects. When I go to System Preferences all the alert sound effect choices are grayed out. When press the volume buttons, can't adjust settings and there's a strike-out symbol underneath the bars.

Any ideas?

Thanks in advance for any help.

Mine did the exact same thing a couple of months ago. The sound card had failed and had to be replaced under warranty. I would make a Genius Bar appointment if you live near an Apple store.

Yeah it sounds like a sound card problem. it shouldn't be that expensive to fix but I don't know exactly what mac will charge you

I had a similar problem, called Applecare and had to go through a few steps with a tech, including resetting the PRAM. Does it sound the startup chime? Mine didn't and I couldn't adjust the volume at all. In the sound settings, there was no output device listed at all. I had to send it in for repair and when I got it back my repair order read:

The following/or parts were used to service your product:

632-0604 FLEX ASSY, AUDIO, M82


Not sure what parts that includes, but it was in and out of repair really quickly. DHL on the other hand took over a week to get it back to me after they picked it up from the repair center. Apple was good on their end, DHL was frustrating.

My MBA lost its sound a few days ago. I've read elsewhere that folks have had their audio cards replaced and the problem happened again. My dilemma is that I'm in Iraq. I dread sending this in and I can't even call Apple to set it up. They offer no way to contact them except by phone. Sort of hard without phones readily available. Ideas??
