I have the same problem on my "ATI Technologies Inc RS880 Audio Device [Radeon HD 4200]".
pavucontrol shows audio streams but there is no corresponding sound. I've just installed alsa-hda-dkms 0.201110231811~oneiric1 and the problem persists. The only output alsamixer shows is S/PDIF. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/864735 Title: [GT5676, ATI RS690/780 HDMI, Digital Out, HDMI] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/864735/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
