I had a very similar problem for the longest time with Hardy. It wouldnt allow concurrent musicp laying. Earlier today the damn sound just stopped working altogether, even after restart. I fixed it by doing the following:
1) System-> Preferences -> Sound. I set everything to ALSA 2) I then restarted. No dice. I then did 'sudo alsa reload'. It complained about other devices still using the sound device. One of them was the mixerapplet (standard) and the other was mplayer - which is weird because i never run mplayer intentionally. It turned out that firefox fired it up to play some embedded audio on wikipedia - one restart ago, iirc. 3) I did 'kill -9 <the mplayer process number>' 4) Did 'sudo alsa reload' again. It worked this time. And now i have overlapping sound. yay! -- sound only works in one program at a time https://bugs.launchpad.net/bugs/220073 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
