Hi All,
I’m trying to connect a volume knob controller extension board to the Up2Stream 2.0 Amp Mono v4.
However, when I connect the 4-wire cable to the GND, GPIO1, and GPIO2 on the amp, I get an incredibly loud noise when turning the knob, and it doesn’t work at all. I noticed that some places mention it only works with v3. How can I solve this problem? Unfortunately, the project was designed to work with just the volume knob.
Can you help me with that?
