Now I'm using a DAC2 HD and DSP Module.

I want to control a volume via amp only.

Please let me know how to disable HifiBerry OS Volume control.

  In HiFiBerryOS, you can't disable volume control.

  Dear Hifiberry Team,

  I also would like to disable the software volume control or look it at 100% and use the Interaction events for volume up and down to control an external amplifier. Is there a way to manipulate this volume control handling via a change in the internal config files?

  kind regards,

  No, there isn't.

  To create a feature request for internal/external volume control I could file a feature request  in the github?

  You can, but this definitely will have a very low priority for us. If no other user looks into this, this probably won't be implemented.

  BTW: What you are looking for is not possible in general. Most services don't use "volume up/down" events, but directly set the volume. In this case, you can't use this approach as the volume of your external amplifier is unknown to the HiFiBerryOS system.

  Ok understand, that makes it pretty specific to the used audio hardware. In my case it could still work since the amplifier could work with a setVolume command... but of course then the interaction for "set volume" would have to be added and a mapping due to different volume scales of different amplifier.  Gets all pretty complicated ...
