I use RCA stereo phono jack on my CPS2 VS2 all be fine
JAMMA mono speakers was unactive
audio come only from RCA on A board
I think that this is correct
if Q-sound is marked audio come out only from stereo RCA R i L on A board
on mono audio come out only to JAMMA
yesterday game run without any sound
when game boot I hold volume switch down on 5s
next i use up volume switch - still no sound
I checked on test sound mode (7.1) and Q-sound is marked
I change sound mode on mono and game run with sound on JAMMA
I altered again sound mode to Q-sound
- game run I get sound on RCA (A board) but speakers still play
both work in the same time
only L RCA work
R RCA - any sound
game still stuck on mono
