Analogue Nt Mini no audio!?

[Elrinth]

I can hear the expansion audio, but it sounds weird, but normal audio is totally gone.
I try running blaster master and there is no audio at all.
I try running MADARA (vrc6 game) and there is audio for expansion channels but it's wrong notes sometimes.

Edit: Seems I had to turn on the VRC6 swap to make it work, else it sounded like crap
