'Twas brillig, and Aitor Pazos at 22/01/11 23:15 did gyre and gimble: >> 1.

We rely on ALSA to support this, but obviously surround51 or any other analogue surround system isn't working. I suggest you try to debug at the ALSA level using e.g. speaker-test -D surround51:0 -c 6 If the surround51 thing works, then PA should automatically see it.
