I started having this in my fresh install of Hardy. I do not have USB sound. I have a PCI Razer Barracuda (CMedia CMI8788), attached to surround speakers. For me the erratic volume control behavior was only associated with the "Master" channel, and happened whether I used keyboard volume keys or mouse to adjust. I got around this problem by setting the master channel to full and hiding it in volume control, so only PCM showed. I then right-clicked on the Notification Area volume applet -> preferences and switched to PCM. I then went to System -> Preferences -> Sound and chose PCM at the bottom as the track controlled by keyboard.
Fixed it for me. -- [Gutsy] Erratic volume control behaviour https://bugs.launchpad.net/bugs/158590 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
