Yeah, that line appeared in the terminal.

I downloaded pulseaudio 3 from debian experimental. The problem still 
persists and it appears in every kind of audio application. It seems to 
me that OOM is wine-related, so I guess it is not related to my problem.

I'm not sure how to figure out whether I'm using module-combine-sink|. I 
can't find it in /etc/pulse/default.pa . I use a Lenovo T61 Thinkpad 
that only has an analogue |audio output so my guess is using 
module-combine-sink wouldn't even make much sense?

This is what I got last time it crashed with pulseaudio 3 installed:

I: [pulseaudio] sink-input.c: Freeing input 8 "ALSA Playback"
I: [pulseaudio] module-stream-restore.c: Restoring device for stream 
sink-input-by-application-name:ALSA plug-in [wine-preloader].
I: [pulseaudio] module-stream-restore.c: Restoring volume for sink input 
sink-input-by-application-name:ALSA plug-in [wine-preloader].
I: [pulseaudio] module-stream-restore.c: Restoring mute state for sink 
input sink-input-by-application-name:ALSA plug-in [wine-preloader].
I: [pulseaudio] sink-input.c: Created input 9 "ALSA Playback" on

I: [pulseaudio] sink-input.c:     media.name = "ALSA Playback"
I: [pulseaudio] sink-input.c:     application.name = "ALSA plug-in

"sink-input-by-application-name:ALSA plug-in [wine-preloader]"
I: [pulseaudio] protocol-native.c: Requested tlength=40.00 ms, 
minreq=10.00 ms
I: [pulseaudio] protocol-native.c: Final latency 50.00 ms = 20.00 ms + 
2*10.00 ms + 10.00 ms

Followed by a bunch of these:

I: [alsa-sink] alsa-sink.c: Scheduling delay of 1.09ms, you might want 
to investigate this to improve latency...

And finally:

Killed


It takes some time to actually crash which makes reproducing it 
time-consuming. Is there a way that I can instantly test whether it's 
the realtime thread problem you were talking about?
