Phantasy Star Portable 2

[Merik2013]

I've been searching for a solution and trying different setting in an attempt to fix this problem for the past couple of days to no success. The audio for the game makes constant popping and crackling sounds on at least the most recent PC version of the emulator (1.4.2). This is particularly noticeable in the Little Wing lobby. Like I said, this is constant. It's not tied to transitions or some other nonsense like game speed as the emulator is running at a constant 100% with a 1% variable. Does anyone have any suggestions on how to fix this?
