If sound won't work, here are some things to check.
- Go into any of the mixer applications and make sure nothing important is muted
- /dev/audio and /dev/dsp
- permissions should be set up so you can read and write; typically, they will be owned by user "root" and group "audio", with read/write permission for user and group, and you must belong to the "audio" group.
- lsof each of these files (e.g. "lsof /dev/audio") to be sure neither is locked by another application (some audio applications can crash while leaving the audio device locked). Once unlocked after having been locked, you may need to restart the audio system for it to work again.
