2xPSG MegaMod: PWM waveform does not play correctly after stopping playing music.
It is correct at 17 seconds, but there is a problem at 2 minutes and 30 seconds. It seems that this problem exists for all PSG chips. As long as SNDH music is played for the second time, PWM cannot be reproduced normally. Playing music continuously does not cause this problem, playing Alla again after stopping the music will trigger this bug.
Here are the recording files and VGM. Compare_PWM_using_AY8910 Atari_ST_SNDH_VGM.zip
