Those players do not implement all of the MMC5's audio capabilities, specifically the PCM channel and its automatic "read" mode.
The quick fix is to write 0 to $5010, not 1.
When you put it into read mode it will automatically send samples to the PCM channel any time there is an access to the $8000-$BFFF area (including running code from there).
By the way, if you want to test the MMC5 PCM features available in various emulators, here's an NSF for that.
If you want to file a bug with other emulators that are missing support for the MMC5 feature needed for track 1 or 2, you might refer them to this test ROM.
Ha Thanks man.
Sorry I wasted your time. I'll go annoy Sour over at Mesen!
I'll make sure to favor nsfplay in my future testing for the extra accuracy.

Hi Brad.
Mat from FamiStudio here.
I'm adding MMC5 support and NSFPlay seems to be the only one creating a loud buzz when playing my NSF. I validated with Mesen and NotSoFatso and both play very clearly. Not sure if its my fault of not. Has anyone reported such issue in the past?
Thanks.
