I just received and plugged in my Digi2 Pro with HifiBerryOS to my DALI Sound hub using the coax.
I was surprised at how low the volume was set when playing Spotify, after some digging and searching the forums I tried changing "min_dB -90.2" to -45.2 in asound.conf. In the webgui I changed the minimum volume to max, 70%. Is this the right way to do this? Will my edit of asound.conf survive upgrades?
I also noticed that the device was using softvol as mixer. Is this correct? I was under the impression that this would cause quality loss of the sound. Can I change this to use hardware?
Below doesn't seem right either, is there any way to set the sample rate higher? DALI Sound hub can handle more, and the Digi2 Pro too, it's one of the reasons I bought the Digi2 Pro.
# cat /proc/asound/card?/pcm?p/sub?/hw_params
rate: 44100 (44100/1)
I know Spotify isn't the best source for good quality sound, but I don't want to make it worse than it is so to speak :)
Edit: is there a way to lock the volume, so it isn't controlled by e.g Spotify and my active speakers control instead?
