It happens with different applications connecting to PA. pa-mbeq is active and everytime a stream begins/ends/pauses(corks?), the problem (see above) occurs.

If pa-mbeq connects to alsa it works. If it connects to bluetooth or another pulseaudio-server via Lan it works not.
I tried another laptop, same debian packages (wheezy) same version, same configuration. mbeq => bluetooth (same headset) works.

So the problem occurs on one of my laptops and if mbeq connects to bluetooth or another pulseaudio server..... ?

Thanks for any help!

Jasmin

Marking as 2.0 blocker for now.
Comment 2 David Henningsson 2012-03-23 04:05:46 UTC
I believe this needs backtrace info to get a hint of where to look. On debian and its derivatives, install libpulse-dbg and pulseaudio-dbg packages before making the backtrace with gdb (use the "bt full" command).

Thanks!

Dropping as 2.0 blocker since we have no information to go on.
