Comment 26 for bug 410933

I can confirm the behaviour kilroy experiences. I did an upgrade from 9.04 to 9.10 immediatly after upgrade there was sound. After reboot no sound. By toggling "Amplifier" sound starts. After reboot there is no sound any more until toggling "Amplifier" again. I have to do that after every reboot of the system.
