In this example the DAC is on card 2, device 0.

  1. Play a simple 8-channel test:
    speaker-test -D plughw:2,0 -l5 -c8 -t wav

    You should hear audio on each channel in sequence.

For applications that only support stereo, you can create four virtual stereo devices and assign each app to a different virtual card.
