Hi,
I'm having the same problem you describe in mpg123. Everything worked
well with Alsa and ymfpci but now when I got a Hoontech DSP2000 I have
exactly the same problems as you.
However, to me it seems like disc activity or high processor load
doesn't trigger the problem. Changing from an empty virtual desktop
to a busy one does as does closing big windows.

I also gave the sound card an unique IRQ hoping for an improvement but
nothing changed.
I use linux-2.4.18 and alsa-0.9.0beta12.
