Public bug reported:

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.

$ LANG=C apt-cache policy pulseaudio
