alsamixer was listing me as having this chipset so I googled. Sure 'nuff, I'm not the only one with issues after the karmic upgrade.
For some reason volume control is controlling the master channel, badly, (it properly registers raising/lowering in alsamixer, from 0 to 100% but if I use the gnome sound control to go from 100% to 0% to 100% it goes from 100% to 0% to 38% according to alsamixer, all the while showing 100% in the gnome control). Additionally, volume control doesn't really work since all of a sudden all sound is going through some minor channel I had initially had muted called "Speaker 3" - the main volume control doesn't appear to control it at all. If I unmute that I can control volume with alsamixer, but that's hardly convenient. Wiping ~/.pulse w/ pulse killed didn't help. The hardware is reported in the gnome control panel as "Internal Audio 1 Input/1 Output" - there is no option to change outputs. There are a number of other profiles, none of which offer an "Input" option, and anyway if I switch to them the output gets screwed up. Changes from "Internal Audio Stero" to "Null" when I do so, and doesn't work again until I restart pulse. I'm guessing from this and the extensive debugging on this thread that support for this device is hopelessly mucked up. So, guess I'm just going to lurk here and watch for developments. 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02) SigmaTel STAC9227 -- [Karmic stac927x regression] No sound after upgrade from Jaunty to Karmic https://bugs.launchpad.net/bugs/400682 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
