have you got your IQaudio DAC work properly in Raspbian Buster?
not having an audio DAC HAT working on the RPi4B is the only one keeping me from upgrading my RPi3B+ desktop
tried Raspbian Buster on this RPi3B+ (my current desktop, but still on Stretch) but there was no audio coming out of my DAC HAT amps....
used the same dtoverlay configs as I did on my stretch setup
thus made me rethink about moving to Buster now.... until this problem (its a problem, not an issue, for me) is solved
anybody else have had their audio DAC HATs worked properly on Raspbian Buster?
