I have just tested in 2.6.12-rc4 and works fine. I even feed the stereo
signal to the 6 channels, so 4 go to my desktop speaker system and one
other pair to may home stereo.

Something is broken in -mm wrt ALSA. If you need me to test some specific
version, pleas just ask.

Side note: trying to load settings from rc4 in -mm says:

alsactl: set_control:930: warning: name mismatch (Surround Jack as Input/Surround Jack Mode) for control #42
alsactl: set_control:932: warning: index mismatch (0/0) for control #42
alsactl: set_control:1030: bad control.42.value type

Hope this helps.
