Bug Description

Binary package hint: pulseaudio

Pulseaudio frequently crashes when I move a live audio stream from my external USB audio sound card (Creative Xmod) to my onboard HDA intel card.

If I start the pulseaudio daemon manually with:
$ pulseaudio -vv

I get this before the crash:
D: sink-input.c: Successfully moved sink input 0 from alsa_output.usb_device_41e_30d0_noserial_if0_sound_card_0_alsa_playback_0 to alsa_output.pci_8086_293e_sound_card_0_alsa_playback_0.
I: module-volume-restore.c: Saving sink for <pulsecore/protocol-native.c$Rhythmbox>
D: memblock.c: Memory block too large for pool: 49152 > 16376
Soft CPU time limit exhausted, terminating.
Hard CPU time limit exhausted, terminating forcibly.
Aborted

This was with Rhythmbox as the only application currently outputting audio. When pulseaudio crashes, Rhythmbox hangs hard and must be killed.

I've not tweaked anything in the Ubuntu 8.10 audio configuration, except for installing the pavucontrol-application which lets me control where to route my audio.

Attaching to pulseaudio-daemon with gdb and reproducing the problem (which is easy) gives this message:
Program received signal SIGXCPU, CPU time limit exceeded.

And a "thread apply all backtrace" gives this for the main-thread:

I have the same problem. Pulseaudio crashes many times, when I playback music with audacious.

im not sure, but can it be, that we have to define a rule for kernel-security stuff?!

my backtrace is:

I have a similar problem when I move an audio stream from the pulseaudio server running on my laptop to the pulseaudio server running on my Eeebox that is attached to my home HI-FI equipment.

Both systems run Ubuntu jaunty with this server version:

ii pulseaudio 1:0.9.14-0ubuntu20.2 PulseAudio sound server

One way to get it to work is to manually kill the server on my laptop, then change the default server with padevchooser.
