Comment 6 for bug 1716235

Okay, I wasn't aware that we can assign one vinyl control signal to multiple decks.
That solves the bug for my use case.

In general I still think it would be better to route just the Aux signal to a deck because apparently Mixxx is trying to detect a vinyl control signal no matter if I actually use it, and thereby spams the log with messages like this
Warning [VinylControlProcessor 1]: VinylControlProcessor could not write signal quality report for VC index: 0
Also the buffer underflow count is increasing rapidly, though I don't hear any pops and latency meter tells me everything is fine.
