[Vm-dev] Linux ALSA sound bug

[Derek O'Connell]

It's possible the hardware (DSP?) does not support interrupts needed
for triggering the callback so that function is not implemented. For
others with a similar problem if OSS does not work then checkout the
dsp wrapper for another sound server, eg, "esddsp" and "padsp" for
ESD/PulseAudio resp.
