Public bug reported: Binary package hint: alsa-base
Alsa does not seem to work after upgrading to karmic from jaunty:
killing pulseaudio and and starting with -vvvv gives the following

Editing /etc/pulse/default.pa

load-module module-detect
This seems to be because module-detect falls back from alsa to oss which

I can probably live with pulse working via oss, but would prefer to find
out what is going wrong with alsa and why it doesnt work
It is possible this is a pulse bug, but without the above pulse changes
alsa does not work with mplayer (forcing vi -ao), but does work with
oss. After the above changes -ao alsa does work with mplayer which I
suspect is pulse offering an alsa input
