Well, I took the plunge and got an N6ii second hand (with A01 module) and new R01 motherboard. I got my music loaded up and checked everything worked with the A01 motherboard (being a new-to-me DAP), and all was well.
But, after switching to the R01 board I can't get it to work. I can start play but just get no sound at all. I've tried a factory reset and a few restarts but nothing is working.
The N6ii seems to recognize that there's a new motherboard in place, as the audio settings page has changed:
The only thing that seems different between the R01 and A01 boards is that the A01 came out with this little black sticker on the back. The R01 shipped with same sticker. Do you need to cover those two circles with the sticker for it to work? Seems like an unlikely solution, but not sure what else could be happening:
I'm running firmware version N6MK2_2.3CN_20210511_1656.
