I have recently purchased and set up an AMP2 on a RPi4 2GB running Moode.
I have noticed a buzz when playing 16/44 flac files. This does not appear to happen with playing 24 bit flac files and is not there when no music is playing.
I did find a previous post from 2014 that referenced this same issue and the resolution was to SSH in and reduce the master volume down to 75%.
Unfortunately, the instructions to do this don't work, although I am not surprised because this was 6 years ago.
Does anyone now how I might resolve this issue?
