I installed RuneAudio on a Raspberry Pi 1, and use it with a Creative XFi 5.1 USB sound card. This works out of the box, so really great
On the XFi, there is a volume button (and remote control) which can be used with LIRC. I have sucessfully configured LIRC to receive the voume up/down events, but I'm having trouble to make it behave well.
I configured LIRC and irexec to control mpd through "mpc volume +1/-1" commands. This works but it is sluggish to respond and mpd crashes regularly when playing with the volume knob quickly. I then have to manually restart it with "systemctl start mpd", so I would prefer to control the Alsa volume directly instead.
Unfortunately, the XFi does not have hardware volume control. In fact, in alsa-mixer, there is only one control available, that sets the power led status
Now I added a software volume control in alsa, following the documentation here:
But changing this volume does not influence the volume of mpd/runeaudio system in any way.
Does anyone have a suggestion how I can control the "master" volume of my runeaudio setup?
