    ALSA Audio stopped working in 9.04

    Running 2.6.28.11-generic kernel & alsa 1.0.20 (manual compile) on Kubuntu 9.04. HDA Intel, AD198x Digital (IEC958 (S/PDIF) Digital Audio Output); I am using the S/PDIF.

    Everything worked fine until I installed some bug & security updates for what I thought were non-related (to audio/alsa). After a reboot, I could only get analog audio to play normally. To get digital audio to play I had to play analog audio and then play the digital audio (play the movie) while the analog was playing. However, if I paused the movie w/ digital playback, I would have to repeat the process to get the audio back.

    Then I decided to reinstall gstreamer0.10-alsa; no help. Then I reinstalled alsa-base (to switch back to 1.18) but after a reboot it still shows v1.20.

    So now I'm stuck with only system sounds playing (bootup & shutdown), gmplayer gives the [AO_ALSA] Unable to find simple control 'PCM',0 error. And a check in alsamixer shows the card and chip as PulseAudio.

    I think I need to blow away the alsa 1.20 but don't know how to do that...suggestions?

    If you are using pulseaudio with KDE4 you should read this.

    You also might want to upgrade to pulse0.9.15 which will make controlling the digital outputs easier. There is a PPA for pulseaudio 0.9.15 here
