Well, acraig, it turns out that starting XMMS before PS just postpones my computer crashing. So, still looking for a solution.
Induane - I can play sound from both. I have the sound turned off on PS, because if I don\'t then I hear music from both at the same time, which is confusing, although sometimes an interesting effect.

It seems like a memory leak, but I suspect now that it might be XMMS\'s fault, because I just had the same problem happen when running XMMS and Blender together (without PS).
Does anyone have a suggestion for a different program I should be using for netcasting while playing PS? (Without changing to Slackware. I don\'t know what you\'re thinking, Baston. Debian is the real Linux!) What is amaroK? I only use XMMS for audio streaming; would amaroK be better? What do you mean by \"the full duplex?\"
Thanks for the help, everyone!
