Currently Being ModeratedJul 20, 2010 8:47 AM (in response to Sujit Pavithran)I have the same issue. Although I'm starting to think it's a hardware problem.
I have no sound from either my internal speaker or from headphones, opening garage band brings up an error code "Core Audio: Selected Driver not found. (-10202)"
Pressing the volume buttons on the keyboard flashes up the level indicator on the screen but it does not change, and also a little "O" with a line through it appears underneath. The Sound Preference panel says "No Output Devices Found", and the volume slider is grayed out, set to max, with a grayed Mute box ticked.
Is yours the same?
I'll do some more digging and let you know what I find?MBA, Mac OS X (10.6.4)
I have exactly the same issue! and what's more, apparently we aren't the only ones... a whole bunch of folks are facing this problem, so it can't be a hardware issue... i think it's a bug with some software update - perhaps iTunes. Will also check more Mac user fora, and keep you updated if i do find a fix.MacBook Air
Currently Being ModeratedAug 14, 2010 8:02 AM (in response to Sujit Pavithran)I have the same problem. However, for several days, sound would come back with a reboot, which leads me to believe it is software, not hardware. But now, even rebooting doesn't work. I don't even get the boot 'chord'.Macbook Air, Mac Pro
Same here, I can hear a very very little sound very I put the volume into the highest. On the sound output preferences, it just shows the selected device has no output controls.
Same problem as in Boot camp too, so I think it must be driver related.MacBook Air, Mac OS X (10.6.4), 2GB ram
Lack of sound on is usually a hardware failure. On some MacBook Airs, the cable connecting the speaker to the system goes south.
I would take the machine to an Apple Store or an Apple-Authorized Service Provider and have it looked at.Home: 2.93Ghz 24-inch iMac, iPad Wi-Fi, Time Capsule, iPod nano, eMate & more., Mac OS X (10.6.4), Work: 2.8Ghz 15-inch MacBook Pro (Matte) & some Windows boxes.
Currently Being ModeratedAug 30, 2010 6:42 AM (in response to Sujit Pavithran)I'm having a similar issue with my new MacBook Air. My speakers work to play movies, etc, but none of my alert sounds or iChat sounds work. I rebooted and it worked fine, but then they stopped working the first time I woke the computer up after the reboot. Am I correct in guessing it's a software issue because the speakers do work with other applications?MacBook Air, Mac OS X (10.6.4)
Your problem is not the same as mine.
I have nothing, can't use headphones nothing.
Itunes doesn't show song is playing
MySpace jukebox doesn't show song is playing etc
No sound what so ever.
I do have sound on a lucky day but they are now further apartPC, Windows XP Pro, MacBook Air

Online support indicates that the PRAM and NVRAM need to occasionally be reset.

This document explains how to reset the parameter random access memory (PRAM) and nonvolatile RAM (NVRAM) on Macintosh computers.
Important: If your computer does not retain parameter RAM (PRAM) settings when it is turned off, this generally indicates that the battery needs to be changed. Refer to Macintosh Family: Batteries and Part Numbers.
Resetting PRAM and NVRAM
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.MAcbook Air, Mac OS X (10.6.4)
