I can confirm all these bugs. I have a M-Audio Revolution 5.1 + MSI K9N Platinum/NVidia 570 MCP/Realtec ALC883/AC'97/Azalia 1.0/Intel HD Audio/Whatever and I'm running the AMD64 version of Ubuntu 6.06.
Partial workaround (thanks Nespa): Open terminal and type: sudo gedit /etc/modprobe.d/alsa-base Add the following lines: options snd-ice1724 index=0 options snd-hda-intel index=1 I suppose there is a way to make alsamixer unmute the left channel at startup? It's quite frustrating not to be able to use keyboard volume buttons as I don't have a volume knob in my active monitor speakers. Only the volume of the left channel changes, even if the gnome mixer is set to control both channels at the same time. Gnome mixer application doesn't work well with the Revolution: it forgets what tracks it's supposed to show and it has DAC, DAC, DAC 3 and DAC 3 tracks instead of plain DAC and DAC 1 like alsamixer. Only the second DAC / DAC 3 affects the sound volume (the changes are mirrored to the first DAC / DAC 3, but not the other way around). I wonder if it's possible to write a more user-friendly driver, all the DACs paired and renamed to Front, Back, etc. according to the card in use (5.1 or 7.1). A master channel would be nice, too. -- default sound card is randomly set on boot, settting default sound card through gnome-sound-properties did not work correctly, changing volume through hotkeys (on logitech multimedia keyboard) is bind with card0, not with default card https://launchpad.net/bugs/45786 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
