I have recently set-up my rPi 4 with a hifiberry amp+ and balenasound. Everything is working fine and the sound quality is really good.
I am completely new to this kind of project but enjoy learning about the topic and like a challenge!
I know it is possible to use a rotary encoder connected to the GIPO pins on the rPi as an external volume control nob for other music applications such as volumio. Can a similar thing be used for Balena sound? And if so can anyone point me in the right direction so I can learn how to do it?
