I can control the output level of my DAC using:
amixer -c 1 -D "hw:[device name]" set PCM [n% or ndB or mute or unmute]
Is it possible to implement something similar to allow client hardware volume control? I've seen the reference to Synchronator in another post but afaik alsa is not supported.
Feature request for hardware volume control option
Re: Feature request for hardware volume control option
What does "alsa is not supported" mean? MPD can control any ALSA mixer, just like the "amixer" program. If amixer can control it, then it's "alsa supported".
