Step by step instructions:

1) Open envy24control.

2) Switch to the "Patchbay / Router" tab.

3) Select "Digital Mix L" in the "H/W Out 1 (L)" channel strip and "Digital
Mix R" in the "H/W Out 2 (R)" strip.

4) Switch to the "Monitor PCMs" tab.

5) "L/R Gang", rise the fader and unmute "Left" and "Right" in both the "PCM
Out 1" and "PCM Out 2" channel strip.

The "Digital Mix" setting will mix down all PCMs to  a stereo pair and
output it on H/W Out 1 and 2.

You should now have sound, but at a much lower level than when you had "PCM
Out 1" and "PCM Out 2" selected in the "Patchbay / Router", so you might
want to raise the volume output level in the application that is supposed to
make some sound.
