I am new in the community and have a problem with my hifiberry DAC+ ADC pro and hope you can help me.

I want to use the analogue port and the digital connection (Spotify). The switch between the sources works fine. I want to increase the level of the analogue port (ADC). This works when fine using alsamixer or by commandline:

         amixer sset ADC 40

After switching to spotify and again back to the analogue source the value of ADC switches back to the initial value of 23

Question: where is the initial value stored of how can you change the value permanently.

Thanks for your support.

  You mean on HiFiBerryOS? You can't do this as every source can directly control the volume. That's what's happening here.

  Thanks for the quick response.

  Yes,  I'm using the actual version of HifiBerryOS (20220228)

  The signal of the analoge input is to weak in comparison to the digital input as example for spotify.

  I have found no possibility to correct this in the graphical userinterface. So I switched to the basic commands of the operating system "amixer" to increase the level of ADC only. This works fine, but it is corrected to the initial level as soon as you switch again from analog to digital. 

  Did I missed some options in the graphical user interface or is it possible to change the default value a config file?

  Unfortunately there is no way to set this in the UI.
