When I enter anything into the Mixer Control box, it doesn’t save and just disappears when I click Save. Plugin works fine otherwise, just can’t get it to update the main Digital Volume Control on my HiFiberry soundcard. The side effect is I can put volume to max in Spotify and it’s still very low coming out of my speakers because it’s not syncing with the master volume.
Update:
I ended up just using spotty plugin from my other pi with max2play and it works fine that way. Still, that option shouldn’t delete the entry with no notification on why.
