[PROBLEM] Vollume via rotary slow response

[FrankVer]

Hardware:
Raspberry pi 4 8 gb.
Hifiberry amp2
Rotary at pin 23 and 24.

Moodesetings:
Volume mixer: software
Rorary encoder 110 4 4 24 23    : tried many options.

Hi all, maybe someone has a solution for the response of my rotary what i use to control the audio volume.
The problem is that the response is very slow .

Only when i set it to hardware control than it works responsive.

Please advice, rg Frank

Just set MPD to use Hardware volume.

[FrankVer]

Hi Thanks for the quick response.
Just set to hardware control.
Now when i use spotify connect and turn the rotary then spotify gives no sound at all.
while spotify client is still connected and playing.

Many thanks frank

[Tim Curtis]

Rotary encoder feature is for MPD only. Volume for Spotify is controlled at the client Spotify app on your phone, tablet, etc.

[FrankVer]

I know that spotify is controlled by other devices,
so it is normal that spotify stops when the rotary is turned.

Many thanks again Tim.

[Tim Curtis]

I have no idea why Spotify playback would stop, the rotary encoder driver just sends volume commands to MPD.
