User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.4) Gecko/20091016 SUSE/3.5.4-1.1.2 Firefox/3.5.4

pulseaudio sometimes breaks. It would start using 100% cpu, causing any program using it to hang. 'killall pulseaudio' solves the problem for a while. Seems to happen only if two application are using sound at the same time.

Reproducible: Sometimes

Steps to Reproduce:
1.use two application that uses sound (for example amarok and smplayer)
2.
3.



this is the sound card:
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 60)
driver is snd_via82xx
and after the break /var/log/messages is full of this:

PA seems not working well with via82xx driver.

Could you try tsched=0 option for PA default configuration?
In the line of "load module module-udev-detect", add "tsched=0".
