I'm running Edgy (clean install on a reformatted drive) on an nforce2 chipset. I get a similar issue -- audio apps produce no sound on an intermittent basis, and they give no error messages.
The app gui indicates the app is playing the media or stream happily. If I go to the sound prefs tab and try to test a sound, I get this error message: audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Resource busy or not available. -- /dev/dsp busy, but no program using it https://launchpad.net/bugs/76876 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
