That's it, the master monitor level, it's what is used for the digital
mix (which is what is used for being able to monitor what is being
recorded while listening to audio that has been recorded. What is he's
trying to do? For applications that only use stereo out, channel 1 and
channel 2 would be used as the volume for the application (although
typically the application would have its own volume control, which is
usually controls what 2 outs you have mapped to the card).

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.
