Possible fix (worked for me, thanks to gnubien on #alsa): add this to /etc/modules options snd-hda-intel model=m2-2
Changes will take effect on reboot. To get it going *now*: lsof /dev/snd/* and close every app listed (easiest to do so through the process manager / task manager thing), then do it again to make sure there's no output (meaning all the sound apps are closed). If there's no output: sudo modprobe -r snd-hda-intel then sudo modprobe snd-hda-intel and sound should be there. -- Sound works sometimes on boot - sometimes not https://launchpad.net/bugs/57455 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
