Audio desyncs after playing more than a minute.

I've noticed extreme audio delay when trying to play games on the latest Mupen 2.5.9. I understand that lowering primary buffer target should decrease latency, but it doesn't appear to change anything from what I can tell. Are there any other settings that I can change to sync the game and the audio. I really don't want to go back to Project64. I've tried Sin and Punishment and Perfect Dark with various graphic plugins on Win 10.

Chiming in to confirm. There's a parameter in the config file called "AUDIO_SYNC" which is set to false by default. Setting it to true fixed the gradual audio lag for me.
