This bug is VERY old, but I found a simple solution. (It's been a long time since I solved the problem too, just forgot to share it here -- sorry)
Inserting: options snd-intel8x0 buggy_semaphore=1 buggy_irq=1 into /etc/modprobe.d/alsa-base solves the problem in ANY version of Ubuntu (Breezy, Dapper, Edgy, Feisty, Gutsy and Hardy). Attachment: my alsa-base file already with the snd-intel8x0 options. ** Attachment added: "alsa-base" http://launchpadlibrarian.net/15860879/alsa-base -- Inaudible sound for snd-ali5451 after dist-upgrade from Hoary to Breezy https://bugs.launchpad.net/bugs/36040 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
