Hello people! Thanks for a great product, the Mrs is extremely happy to finally have a working multiroom solution.
One problem we have is that in the kitchen, I am running a Hifiberry Amp2. That means the only way of volume adjustment is through the Spotify phone client. Already at 10-ish % volume, the volume is quite loud. Even at the first tick above zero, the volume is still a bit too high for some quiet dinner music.
I had hoped that I could scale the volume span down by setting SYSTEM_OUTPUT_VOLUME to lets say 10, but it does not seem to work that way.
Any ideas on how to make the lowest volume setting a slightly lower output? Thanks!
