I had similar problems on upgrade running from CD gave me *very* quiet sound.
Upgrading left me with no sound I had error messages about unknown symbols (sorry I didn't capture them) I've reverted to an earlier kernel and sound works fine again :-) uname -a Linux ethel 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686 GNU/Linux lsmod | grep snd snd_rtctimer 4640 1 snd_hda_intel 315952 3 snd_hwdep 10500 1 snd_hda_intel snd_pcm_oss 42752 0 snd_pcm 80388 2 snd_hda_intel,snd_pcm_oss snd_page_alloc 11400 2 snd_hda_intel,snd_pcm snd_mixer_oss 17792 1 snd_pcm_oss snd_seq_dummy 4868 0 snd_seq_oss 35456 0 snd_seq_midi 9600 0 snd_rawmidi 25984 1 snd_seq_midi snd_seq_midi_event 8448 2 snd_seq_oss,snd_seq_midi snd_seq 54256 7 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer 24452 3 snd_rtctimer,snd_pcm,snd_seq snd_seq_device 9612 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq snd 57508 19 snd_rtctimer,snd_hda_intel,snd_hwdep,snd_pcm_oss,snd_pcm,snd_mixer_oss,snd_seq_dummy,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 8800 1 snd -- [hardy] Sound card hda Intel doesn't work with kernel 2.6.24 series https://bugs.launchpad.net/bugs/211644 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
