Hello everybody... I am working on a (potential) /dev/audio (q.v. Sun) device
for Linux that would allow one to play sound through a digital-to-analog
converter attached to the parallel port... the only problem is that we need at
least 8000 samples output per second... the last time I checked the kernel
sources, the interrupt rate was preset at 100 Hz. My question is: how much
can we crank this up and keep the kernel alive on most hardware? What
will the additional load imposed be if we increased the interrupt rate 80
times? If anyone has any information on this, please let me know. I need to
know whether or not my project is feasible.

All for now,

Noam
