Yes, like this. The sound is not crackling at all. I don't know if "suttering" is the right word.
Also, when VSync is disabled, the emulator shows 60 FPS sometimes going down to 53 even though it's way worse, and when VSync is enabled it shows the FPS varying between 40-60 sometimes going down to 30, which I feel is more accurate. Again VPS stays at 60. It's like it stays at 60 FPS for 10 secs, and then 5 seconds at 40, 10 at 60 etc.
This is not something that happen after like 30 minutes of gameplay. It's right after 5-10 seconds.
