Ok. After playing around a while with alsa, I managed to make my soundcard unusable. Now, on every restart the soundcard was muted and I had no control on the volume, as stated above.
Now I followed this guide: http://ubuntuforums.org/showthread.php?t=843012 I found out, that "sudo alsa force-reload" did the trick. Immediately the soundcard was able to output audio files. After the next restart there was no sound, again. The pulseaudio mixer was set to 0. I set it to 100 and voilà, I had audio output. I thought, now it's solved. Let's try a restart. After the restart I had the first problem again. A muted soundcard with no possibility to unmute. Pulseaudio mixer and any other mixer weren't unmuted or set to 0. No question, "sudo alsa force-reload" did the trick again. But this should only be a temporary solution. Pulseaudio should play better with alsa, or alsa with pulseaudio, or both with the soundcard. ** Description changed: Binary package hint: pulseaudio ubuntu jaunty 9.04, updated from ubuntu intrepid 8.10, newest updates, pulseaudio 1:0.9.14-0ubuntu20.1, alsa-utils 1.0.18-1ubuntu11 In intrepid pulseaudio and alsa worked fine. Now they are broken. There are several similar bug reports i read before. But this seems to be another problem. After a clean restart (no suspend or hibernate) there are two possible ways for pulseaudio and alsa, and the decision, which one is gone, seems to be random: * 1st way One time playback of audio and video files works fine in vlc, totem, amarok, firefox flash addon. * 2nd way And the other time playback of audio files looks fine, but there is no sound. Perhaps it plays on a channel/card that's not existing. Perhaps something is muted. Perhaps there's a misunderstanding between pulseaudio, alsa and the soundcard. Notice: beep (via apt-get install beep) always works fine via soundcard (not the system speaker). I checked several mixers: gnome-volume-control, alsamixer. Everything is unmuted and set to 100. * Pulseaudio Mixer Master => unmuted, 100 * Alsa Mixer (Intel) Master, Master M, Headphon, PCM, Line, CD, Mic, Phone, IEC958 P, PC Speak, Aux => unmuted, 100 * Oss Mixer Speaker, PCM-2, In-gain, Digital-1 = unmuted, 100 - What does't work + What doesn't work * "alsamixer -c 0" for setting the "front" volume to "100", because there is no "front" * purging and reinstalling alsa and pulseaudio It's driving me crazy. Rebooting 3 times for a working audio playback is not what i wanted.
