You have configured 4.0 channels (quadro) output with additional stereo
redirection output. 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.

OK.
