USB DAC and Hardware Volume - cdlenfert - 10-14-2019
On previous devices I've set up with only Shairport-Sync I'm able to put in set up my .config file to utilize my USB DAC's hardware volume control. The benefits are much faster volume changes and louder overall volume output.
I'd like to do the same for Moode, but when I go into MPD config, only the Software volume setting will output anything. I have to change the Alsa volume to 100 and then set the volume dial in the moode web interface up above 40 to get any sound output.
Is there a way to use Hardware volume with the USB DAC and generally get volume configured better on my setup?
