I was recording through pulse in audacity and moved the stream around in pavucontrol when it crashed.

Fortunately, I had the pulse verbose log on when it happened.

Is this reproducible in current Lucid? I pushed a ton of PA changes yesterday.

I haven't been able to get any sound in Ubuntu through several distributions when i connect via an HDMI cable. The machine's dual boot and sound is fine in vista. I had hoped Vista would fix the problem, but I still get no sound, supposedly because of no sound devices. The problem may be that I have too many--the EVGA 630 MOBO and now a ATI combo TV and sound card connecting to the PCI-E port.

That version is no more supported
