I'm running an IBM Thinkpad T40, just freshly installed ubuntu 9.04. The problem i have is sound not working for multiple programs. I can hear the login sound, however, sound doesn't work well after that. I don't get sound in audacious, pidgin, or firefox. however, if i change audacious's sound output to OSS, audacious plays sound. when i go into system->preferences->sound i do not get sound when testing. Only if i change the device to OSS, it will play sound, but i have to stop the song playing in audacious, else i get the error
audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Could not open audio device for playback.
such the same, sound works in pidgin, provided audacious is not playing a song. even with audacious off, firefox does not play sound when watching a youtube video.
sound was working perfectly without any problem in 8.10, and was even working in 9.04, however has suddenly stopped for some reason.
any ideas on how to fix this, maybe re-installing sound somehow?
sound device is listed under lspci as:
Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)
i'm not sure why it stopped, and have tried rebooting to no avail.
have also checked the volume control applet to ensure none are muted or down.
same in firefox, pidgin, and audacious.
