I've been trying different setups to both play just to certain channels
to test and they didn't work.
I then found a windows machine to put it in and test got 5.1 working on
that machine (win2000 is restricted to 6 channels), then placed it back
in the linux box
Made a new configure - not sure how it differs from all the
configurations I tried before - but now it works (7.1).
Would the windows driver have changed any settings ALSA doesn't?
With this configuration it plays a 2 ch source through all my speakers:
(ie mplayer -ao alsa9:convert whatever.mp3)
