The .asoundrc I attached uses softvol to create a master channel. (Normally one can not overwrite the master, but in this case it does work since master controls nothing) It also upmixes to 5.1.
The problems lie with the driver, and will not get fixed judging from what upstream has to say about it. This solution works, but can't be incorporated into a default Ubuntu in any normal fashion. -- Master channel on C-Media Electronics CMI9780 https://launchpad.net/bugs/71493 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
