Description of problem:
snd-sbxfi driver currently supports only one app at a time, so must use something else for mixing multiple threads. Pulseaudio isn't the best way since it creates huge sound lag in many games like doom3. So I use dmix. But I also want pulseaudio work with dmix (and not with hw:0.0 like it does). But when I comment all strings about autodetection in default.pa and load module-alsa-sink directly with device=default (which is dmix), pulseaudio crashes frequently (almost always after 2 seconds of playing entry sound or immediately).

Please provide a backtrace.

(Also PA does not use hw:0. It uses device strings like "front:0" which have a defined channel mapping)
Comment 2 The Source 2008-11-03 12:33:52 EST
Can you please explain the steps I should take to provide backtrace? Is that some kind of log?

Closing due to lack of response.
