Picade Max USB Audio / Reverse the volume control?

Support
1

I just recieved my Picade Max USB Audio

And the Picade Max Encoder (Volume Control)

It’s working just fine, but. Turning the volume control knob clockwise reduces the volume, and counter clockwise raises it. This is backwards to how I would like it to work. There is a schematic for the USB Audio, but none for the Encoder Volume Control board. Is there one avialble?
Also wondering if swapping ENC A and ENC B would get me what i want?

Yes, that should do it. Untested, but from the C source code both pins are fed directly into the PIO state-machine and this should just reverse it.

I traced those two on the audio schematic and it looked safe enough to try. ENC_A goes to GPIO29/ADC3, and ENC_B goes to GPIO28/ADC2
Figured I ask first. Just swapped them around and its working as I wanted. =)
