To handle this 4.0 setup driver needs 2 DACs. As soon as you have only one DAC, all you can setup is one stereo output with additional stereo redirection. It is impossible to make all 3 outputs work, so you should choose which one to disable. > Am I better off disabling everything and then just walking > through one nid at a time trying to establish what's what?
