Hello, posting my issue here.. I really want to like 13.04, but for the sound issue. Things I have tried:
Installed the daily builds package.
Installed pulse audio control
Purged alsa and reloaded
It shows my radeon 7850 as a sound device but no sound... Also I unmuted the sound in alsamixer.
Running kernel 3.8, and after removing alsa base and reloading it, now the sound button on the top ribbon is gone, and all sound options are also gone in system sound settings, but my radeon still shows up in pulse audio control.
