Bug Description
Binary package hint: pulseaudio
Using the module-combine feature of PulseAudio in combination with a USB sound card leads to a crash.
I have an on board Intel HDA and a USB Soundblaster Audigy 2 NX.
If the USB sound card is not plugged in when PulseAudio starts, after plugging in the USB audio device, the next program that tries to access PulseAudio causes it to crash.
Error output from pulse audio:
E: module-combine.c: Assertion '!op->outq_
reproducible every time.
See attached debug log.
Ubuntu Intrepid 8.10
pulseaudio 0.9.10-2ubuntu9
$ cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
1 [NX ]: USB-Audio - SB Audigy 2 NX

I have a similar setup; I've also seen Pulse crash under similar conditions with malloc( )-trashing- related explosions, although I can't seem to reproduce it reliably enough to paste one.
