On Intrepid, I fixed with Daniel's PPA, But I lost the ALSA mixer in
the gnome volume control and in the system - preferences - sound.
I am able to record using pulseaudio now using the flash applet (ALSA
Plugin) and I am able to set the volumes using "alsamixer -Dhw:0"
Current system is AMD64.
I confirm that also...
My setup is Averatec 3200, VIA sound card...
Strangly, there was two ALSA device. If I tried recording with the
first one, I had a crash, but the second one was fine.
Testing on audio did the same as the original poster.
