FPS drops for a split second

[MarOnic]

I'm having a really annoying issue lately where my game runs normally then for no reason the FPS drops for a split second then goes back to normal again. I had this same problem with PCSX2 but I was able to change the synchronizing mode to Async Mix where, even though the game would drop frames for a second, the audio wouldn't be affected. This is good since it's not the game itself that bothers me, it's when the audio basically stops for half a second. It distracts me so much. However, to my knowledge at least, PPSSPP doesn't have an option like this. So does anyone know how to fix this? I feel like I've tried literally everything.
