I have this same bug. I have found a workaround.
$ sudo nano /etc/pulse/daemon.conf Replace: ; default-sample-channels = 2 with default-sample-channels = 6 (Note the removal of the ";" and the changing of 2 to 6 ) Now reboot or do: "pulseaudio -k" And that worked for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/535476 Title: CM106 usb sound card incorrectly detected as stereo only To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/535476/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
