Same experience as Paolo: Google brought me here via Ubuntu forums. Had firefox running with a youtube movie on pause. Shutdown the youtube site and then the device was not busy any more.
Can the OP confirm that FF was not running at the time of finding the bug? Then I can file a new bug - one for the fact that none of the commands used by OP doesn't list Firefox / Flash as the application hogging /dev/dsp... -- /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
