[AudioI] Volumio 3.179 + Audioinjector Stereo?

[Daniel F. Taylor]

Variation on that advice worked!

Rebooted again without the dtparam=audio=on and audio_pwm_mode=2 commented
out.
I get headphones (c 1), hdmi (c 0), and audioinjector-pi-soundcard (c 2) as
choices in playback options on the web interface. Headphones works. Haven't
tried HDMI.

Started alsamixer with c 2 parameter,  Unmuted Master Playback ZC and
Output Mixer HiFi. At first I didn't think it worked but it had just paused
playback. Got music coming out of the audioinjector finally!

Thanks!
