Unfortunately this also didn’t work so I started with the easiest setup and only connected the switch. But even then it’s only recognising one of the buttons. I tried with both inputs and changed to FS1-3 or FS4-6. In the appended video you can see what I’m doing. I tried with a TRS cable in the video. When I do the same with a TS cable one button works like with the TRS cable but the other one is always on. I feel like I’m missing something trivial here or is there another setting I need to make?
