I fixed the audio problem on my new Macbook Air by going to the Audio Midi Setup app in the Utilities folder. Click on Built in Output you may need to click the gear icon for "use this device for output" and/or unclick the checkboxes for mute.

Whoa, didn't know about Audio Midi Setup, I will look into it the next time it happens.

Thanks!
