Hi all. Through more 0.9.12 testing of pulseaudio, I have come accross a problem when attempting to load pulseaudio with a USB sound card detected. The model is in the attached log. I am running alsa driver/lib 1.0.18rc3. In addition to this, when using pulseaudio normally, i.e loading it with no USB card connected, and then connecting the card, pulseaudio crashes with a similar assertion. Due to the nature of the error, I am not sure whether this needs to be fixed in alsa, or pulseaudio. Pulseaudio 0.9.10 works fine with this card.
