should this work with the Pi 2?
i made the changed, rebooted and was then able to select hardware volume control in the MPD settings (previously doing this would cause a horrible noise and kill the output). Now I get audio but it's stuck at full volume - i.e. doesn't respond to the control

in my case it works with the Pi2 yes.

when its stuck at full volume that means the Master channel does not respond. I had the same issue but with the above mods it works for me now.

Did you also enter mixer_control "Master" ? Is it the right hw:x,y for you? Are you on the latest version of Runeaudio?

Cheers

I was originally using the custom Pi 2, Hifiberry AMP build posted on another thread but I switched to the latest runeaudio build and your method above. But the same result - volume on maximum and not controllable.
and here's a weird thing. I edit the mpd.conf file as you describe above but after a reboot it has reverted to the previous file without the mixer settings. tried it three times. same thing every time. Am I hallucinating?

[pmoorhead]

should have asked this in the first place. having edited the conf file directly, what should I change the runeaudio mpd settings for audio output and volume control to? or should i be leaving them untouched?

In my case, once I'm manually editing the mpd.conf file. In RuneAudio MPD Settings page I can't change anything it just displays that the config file was manually changed.
There are no drop boxes etc.

Well when the settings aren't stored then it's clear for me that it doesn't work. Who and why overrides the file?

I'lll investigate a bit.

arch linux is a mystery to me - I can find my way around Debian and it's children but not arch.
the brute force solution in this case is to edit the file then make it immutable chattr +i /etc/mpd.conf

solves the problem but makes me feel slightly guilty. it's like using a goto.
as observed by others on this post, the volume range isn't linear and the first 30% or so of the range is very quiet but that's not a big deal.

Running into the same problem... Erm... Why is Hifiberry amp+ not in drop down menus anyway? Too new?
If I change mpd file using VI command it resets to output for amp+ that has no mixer_control "Master" line anymore. Help?
