Can you post a WAV or MP3 of how it is supposed to sound?

All I can say right now is, that

libvgm doesn't support the AY8930 properly (it is treated as AY8910)
when being treated as AY8910, envelope shape 0xA0 ~~does not work~~ EDIT: I mean "generates no sound", which may be correct behaviour for a vanilla AY8910
