I had an A22p for years, and I never noticed this problem. However, I
sold the machine months ago and can't remember specific configuration
details.

Kick the GNOME config until whatever it's using (esd, right?) doesn't do
that. Or use KDE instead, and set arts to auto-suspend if idle for >
30 seconds. I set arts to auto-suspend while I had the A22p, though I
can't remember whether I had the suspend+resume scripts rmmodding and
modprobing snd_cs46xx or not. HTH anyway,
