I had a look at the manual for the mixer you're using, and it has the ability to change what is routed to each of the 32 USB channels. That's probably a much simpler way of getting the signals that you want to always be in channels 1 and 2. No pulse / ALSA / JACK tweaking necessary. I would suggest changing channels 1 and 2 to be LR mix pre-fader. If your incoming signals are mixed at an appropriate level, that should get you what you need. If they're still too low, you might want to use a group or matrix in post-fader mode to create a boosted copy of the main mix. You could even apply a compressor to the matrix/group with a fairly heavy ratio and makeup gain but a slow release. That would help tamp down the dynamic range for the stream if your performances have widely-varying loudness. --Sean
