Hi
According to manual it should possible use hardware control for volume in HifiBerry DAC+.
I have enabled hardware control from the Volumio GUI, but nothing seems to happen. I can not change volume either from Volumio GUI or DLNA client.
I found some other posts in this site regarding DAC+ and they pointed out that mpd.config must be set in a certain way. I have checked my mpd.config and it is according to instructions in those posts (Volumio GUI seems to set up everything )
Is there some steps I am missing in the setup?
I am running Volumio 1.55 on a Raspberry 2.

Never mind. Now it is working.
After fiddling around a couple of hours, it suddenly starded to work. I cant help others, because I dont know what change that did it…
Hi,
Are you comfortable with ssh and the command line?
Anyway, connect via ssh and do the follow:
root@volumio:~# amixer

Then check the mpd.conf which, in my case, needs the following setup:
[code]audio_output {
type "alsa"
name "Output"
device "hw:0,0"
mixer_control "Digital"
mixer_device "hw:0"
mixer_index "0"
dop "no"
}
[/code]
(Note the Digital, which is the correct setting, I think because of some updates I did).
