And, of course, check the permissions of the sound devices.  On Debian, these
would usually be:

  lrwxrwxrwx    1 root     root           11 Dec 30 20:35 audio -> /dev/audio0
  crw-rw----    1 root     audio     14,   4 Dec 30 20:35 audio0
  crw-rw----    1 root     audio     14,   7 Aug 29  2002 audioctl
  lrwxrwxrwx    1 root     root           11 Dec 30 20:35 dsp -> /dev/dsp0
  crw-rw----    1 root     audio     14,   3 Dec 30 20:35 dsp0
  lrwxrwxrwx    1 root     root           11 Dec 30 20:35 mixer -> /dev/mixer0
  crw-rw----    1 root     audio     14,   0 Dec 30 20:35 mixer0
  crw-rw----    1 root     audio     14,   1 Dec 30 20:35 sequencer

These are all in /dev.  That's a trimmed list obtained via a quick grep of
/dev for audio so I'm not 100% sure if it's complete or if they're all
strictly necessary.  If you want to be sure, do some reading at the OSS
and/or ALSA web sites.

Also check that you are a member of group audio.

HTH,
