OS X Audio MIDI Setup Utility has extra sound control options

macosxhints - A workaround for no sound in non-Apple applications: "I've had sound problems before which affected both Apple and non-Apple programs. To fix them, I opened up the Audio MIDI Setup Utility, which is an Apple-provided program in my main Utilities folder. It has all sorts of settings which might help people. It's like a more detailed version of the Sound control panel in System Preferences. My particular problem was loss of stereo sound, so I had to select 2ch-16bit from a drop-down (and equalize the volume of the two stereo channels)."
