MPD Volume control: Mixer Device <> MPD Software mixed up

[holzboa]

I use Raspberry Pi 2 Model B & HifiBerry Amp2 so "MPD Software" was the way to control volume in previous versions.
I just installed the new version and recognized that using the "MPD Software Volume Control" doesn't change the volume.
Instead i had to switch to "Mixer Device" to achieve the same functionality so maybe preconfigured settings are mixed up.

Otherwise the new version looks and works great - thanks a lot!

Try update: Settings > Addons > rAudio - Update

[holzboa]

Updating was the first step after installing.

Then:

aplay -l
amixer -c 0 scontrols
amixer -c 1 scontrols
mpd-data.sh

[holzboa]

aplay -l

• Setup Volume Control to MPD Software
• Commands:
  • mpc volume
  • mpc volume 50
• Playback page
  • Volume knob should be at 50
  • Set Volume knob to 30
• Command:
  • mpc volume
  • A result should show Volume: 30%

Thanks, that works.
Now I can use 2 settings to control volume but isn't "Mixer Device" made for hardware volume control?

[rern]

Output

• Device - Audio hardware devices, on-board, I2S or USB
• Mixer Device - Available mixers(on-board volume controls) of the current Device
• Volume Control - Controls to use for volume level of the current Device

Your DAC seems to have a mixer device listed. It's better than MPD Software.

Thanks for pointing that out - strange that "Mixer Device" didn't work in r5- or r6-edition with the HifiBerry Amp2.
