My experience ...

With the Fraunhofer wave field system that I had used, it was 4 synchronized PC
rendering in real-time over 88 channels. No crash for at least 10 days of 8~12
hours of work each day, but it was Linux. The 4 soundcards where all hammerfall
from RME (if my memory is good!). The only bug was some sort of buffer "under
run" which was related to the software, this was only for the last day. I
suppose that was a simple problem, having some reference should have surely fix
the thing very easily.

At this time, I was experiencing more problem with an Sony 16/32-channel DAT
recorder only working with 8 channels!

Somebody have experienced simple multichannel wave file playback on Linux? It
seems incredibly stable, at least from my experience.

Have a nice day,
