--- Comment #5 from Aaron Franke arnfranke@yahoo.com --- Does this occur with any other DirectSound games? Have any to test?
Have you tested if this occurs on Windows with your hardware?
What CPU do you have? I downloaded the emulator and the game specified, and I was very minorly able to reproduce this problem on my i5-6600k. The CPU usage hovered around 10 percent (out of all cores, or 40% of one core).
Crackling audio for me was very infrequent but it did occur more on higher sound quality and less on lower sound quality.
