Pulseaudio and Alsa stopped working in Intrepid

[Joshua J Wulf]

Binary package hint: pulseaudio

Previously Pulse Audio was working on my 901 eeePC. Suddenly, a week or so ago it stopped working. OSS works, but pulseaudio and alsa do not. I'm using:

Description: Ubuntu intrepid (development branch)
Release: 8.10

and updating every day.

Do you hear any login sound at all, and have you tried killing pulseaudio and restarting it?

To kill and restart pulseaudio, do the following:
$ pulseaudio -k
$ pulseaudio -D --log-target=syslog

[Joshua J Wulf (sitapati)]

Login sound works.

After running for some time, and every time after a suspend and resume, ALSA and pulseaudio sound no longer works. OSS works.

Killing and restarting pulseaudio fixes this.
