Bug Description
Binary package hint: pulseaudio
Running a live-usb. My sound card is external, connected via usb. A built-in card is physically broken (cracked audio-out jack), so after an installation, I added these lines to /etc/modprobe.
blacklist snd_hda_intel
blacklist pcspkr
The same setup works fine in Karmic (and before).
In my "sound preferences" "hardware" tab I can see my sound card. It is selected and "analog stereo duplex" profile is selected in settings (just as in karmic). However, "input" and "output" tabs don't have a correct content. In the output tab, there's only "Dummy Output, Stereo" option. In the "input" tab, input volume is greyed out and there's nothing in "choose a device for sound input" section.

I looked around and found https:/ /bugs.launchpad .net/ubuntu/ +source/ pulseaudio/ +bug/550350
"pulseaudio -k && pulseaudio" fixes the problem for me.
Michalxo (#550350 bug reporter) claims the problem has been fixed in livecd from 29.03.2010. I've installed from a fresh image downloaded a few hours ago.
