Snes9x on Raspberry pi

[Balthasar]

I have been using my Raspberry pi 4 for Snes emulation with Snes9x. It works fairly well except for the sound quality which is very static like. Link to a video that shows how to install Snes9x on Raspberry pi:

I edited your post a bit seems like webp images are not shown for some reason.
Also pasted the video link so it gets embedded.

I use Lakka on my RaPi 4b, so I don't have as much experience with the standalone emulator, but if audio crackling persists, you may want to look into increasing your audio buffer size and make sure your sample rate is set to 44.1KHz. Outside of that, sometimes there are FPS discrepancies that cause audio artifacts. Not pinning FPS to exactly 60Hz can help with that.

I can attest to this, I'm running Retroarch on my modern PC and for the longest time I was getting audio artifacts and could not find out the reason why. Setty and I found out it was because my monitors are set to 75hz and Retroarch was pinning to 60hz, causing the artifacts, after I changed it to 75hz it was all cherry.

Yeah, moreover, even if your monitor is technically 60Hz, sometimes it's actually hitting somewhere like 59.94Hz, which is enough to cause audio artifacts in some emulators. So even if you have a common refresh rate, it's worth investigating and ruling out.

Lakka is great!

isn't that what FastROM is for?

FastROM mitigates bottlenecks in games that were originally shipped with SlowROM chips. What OP was describing sounds like a common emulator issue between audio buffer and frame sync.
