Hello ! I am encountering some issues with pulseaudio : after some time and for no evident reason PA stops routing the sound. That's what I get with $pulseaudio -vvv : http://pastebin.mandriva.com/13648 (got from a 2.6.29.6_mdv kernel) running $pacmd list-sinks when stuck gives : http://pastebin.mandriva.com/13649
Our pulseaudio integrator Colin Guthrie concluded : "OK, so what is happening is that some alsa level problem is occurring (due to mmap). Pulse tries to recover from this but cannot. The alsa sink (and the whole card) is subsequently unloaded due to this fatal error." And now.. a quick paste from irc : "[00:44:20] <coling> Jul 22 14:04:29 <mezcalero> coling: driver issue i am pretty sure [00:44:20] <coling> Jul 22 14:04:33 <mezcalero> i saw that before once [00:44:20] <coling> Jul 22 14:04:55 <mezcalero> coling: i.e. EAGAIN on snd_pcm_prepare after EPIPE on mmap_commit
This is odd. EAGAIN is returned only at open, read/write and drain ioctls.
Could you track with strace?

It wasn't easy : that big output made my config swap and finally pulseaudio leave for "E: cpulimit.c: Received request to terminate due to CPU overload." but : http://pastebin.mandriva.com/13665
You probably want to repost using a different pastebin... our stupid one cuts the posts short at some pointlessly low value... I've asked about this to get it made bigger but I don't know who looks after it. I'd recommend pastebin.com.
