Sound is crackling when using fast forward mode

The Fast forward mode is working very fluidly on my Lenovo P2 Smarpthone (Pokemon red, or any other pokemon until gen 5). But when i use it, the sound is also trying to speed up, but then it’s crackling. Is there any way to solve this ? Or is there any way, to let the sound render in normal velocity and only the video ?

or is it possible to “overlay” a the game-music like hearing music ? (don’t know, how i can implement music from my phone while gaming)

Because the user interface is on the android version completly different and i’ve found only turtorials for pc-version or other android versions, which have not the same menu-names.

would be very nice, because otherwise i can only play without sound. (btw. i tried to change music latency, doesnt work)

Yes, that’s just a thing that happens when fast-forwarding. There’s no way to fix it, AFAIK, other than just playing without audio.

Hmm yeah. But on N64 the sound was clear, even on double velocity. So it’s a emulator problem.
