I want to use the dummy mixer in Volumio. I have the snd-dummy module auto-loading at boot by adding that module to /etc/modules. It is loaded:
root@volumio:~# aplay -L | grep -i dummy default:CARD=Dummy Dummy, Dummy PCM sysdefault:CARD=Dummy Dummy, Dummy PCM dmix:CARD=Dummy,DEV=0 Dummy, Dummy PCM dsnoop:CARD=Dummy,DEV=0 Dummy, Dummy PCM hw:CARD=Dummy,DEV=0 Dummy, Dummy PCM plughw:CARD=Dummy,DEV=0 Dummy, Dummy PCM
However, when I go to Settings -> Playback Options, under Volume Options, “PCM” is the only available option for “Mixer Control Name”. I’d like to change that to “dummy”.
I can edit the /etc/mpd.conf file directly, but that causes the GUI to behave strangely… Just wondering about the “proper” way to do this.
This is Volumio 2.201 on Raspberry Pi 2.
