I agree that the duplicate is completely wrong. But I also had the same issue as the bug reporter after I installed a Ati Radeon HD 5450 on my system. Here is all I needed to do on my Karmic install to get my sound back: in your /etc/modprobe.d/alsa-base.conf add a line alias snd-card-0 snd-hda-intel (alternatively for digital output: alias snd-card-1 snd-hda-intel) then do a killall pulseaudio and sudo alsa force-reload After that I had my sound back, but in the PulseAudio sound preferences my sound card still doesn't appear. -- intel acl1200 and hd48x0 ati hdmi doesnt work with alsa under karmic https://bugs.launchpad.net/bugs/529137 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
