[PROBLEM] Double volume control?

[ATE-666]

Hi,
My setup is a RPi2 with a Hifiberry DAC+.
Let's suppose that I am playing music at the volume level of 50.
Then, if I use an Android "remote control" such as MPDroid or M.A.L.P. to raise it to 60, I hear the volume increase.
However, if I open the moOde web interface, the volume is still at 50. Then, if I increase the volume from the web interface to 55, I hear the volume decrease, and both Android apps will show the volume at 55.
I would like that volume changes from the MPD remotes would also control the one on the web interface. I have tried to change in Configure / Audio / Volume type from Software to Hardware, but it is the same.

You can try enabling UPNP volume sync but it's a legacy hack and may or may not work going forward.

Code:

# Enable
moodeutl -A add 1024

# Disable
moodeutl -A rm 1024

Thank you; I might give it a try. Or perhaps I will just stop using the Android apps.

I'm having a similar problem, but before I describe it, I have some doubts about the text above. The original poster mentions his problems with two MPD clients and not UPnP streaming players.
Is Tim's reply still relevant?

I mean if he sets the MPD volume with some apps and the moOde web GUI disagrees, there seems to be a disconnect between the MPD and the gui?

[Tim Curtis]

Yes, still relevant.

The volume level in the moOde knob is maintained in parallel but separately from MPD volume and this is why 3rd party apps including UPnP control points + UPnP renderer that use MPD to set volume are unable to update the level shown in the knob on the WebUI.

3rd party apps that want to have the moOde knob updated can refer to the Setup Guide which contains a section that describes an API to set volume.
