MMM-voice mic number changes

[sharmstr]

I have MMM-voice running on a RPi 3 B+. I’m happy to say that I’m not experiencing the latency that I see a lot of other users are reporting. However, I have implemented the Open GL driver to decrease Electron CPU usage fix and its causing issues. The microphone number isnt consistent after rebooting the Pi. Sometimes its 1 and sometimes its 2.

0 [ALSA           ]: bcm2835_alsa - bcm2835 ALSA

 1 [vc4hdmi        ]: vc4-hdmi - vc4-hdmi
                      vc4-hdmi

Does anyone know a way to always force it to be 1?
