To anyone else having this problem, the solution described by Jeffrey, above, worked for me. I was having trouble starting esd back up. Not having esd running meant I could only play sounds from one source at a time (I had to close Rhythmbox if I wanted to hear anything else!).
Here's what I did: [EMAIL PROTECTED]:~$ asoundconf list Names of available sound cards: M5455 M44 [EMAIL PROTECTED]:~$ asoundconf set-default-card M5455 [EMAIL PROTECTED]:~$ esd & I'd second Stefan in saying that it seems this problem should be given more attention. I'd imagine there are several users [who've upgraded from Dapper to Edgy] that are left with a half-working sound configuration. -- Dist-upgrades from Dapper to Edgy break on existing ~/.asoundrc.asoundconf due to missing conf parameters (e.g., Unable to find definition 'defaults.pcm.ipc_key') https://launchpad.net/bugs/67998 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
