Select audio input? #31

Closed t413 closed 5 years ago

t413 commented 5 years ago

Hey, on my Odroid device the default audio device doesn't seem to work for input. Doesn't look like there's a config value for specifying one in particular.

I've used arecord -L to list my devices and arecord -D plughw:CARD=Device,DEV=0 -f cd -d 0 -vv /dev/null to test monitoring the levels with success.

Here's what happens when I try and enable an audio reactive effect:

Got the solution from @not-matt in the group chat:

audio:
  device_index: 0

It'd be excellent to see it in the documentation! Great to get things running.
