Super Metroid MSU-1 Audio Crackling

[buvk]

I am experience audio crackling when playing Super Metroid with MSU-1 (I tried a few different music packs). This is especially noticeable in the menus (E.g. when you select START GAME and the map loads), and in-game when firing Samus's blaster.

I do not experience this if I remove the PCM files. I also do not experience this in other MSU-1 games that I have tested.

I am using HDMI audio, but I also experience this using analog audio.

There does not appear to be any audio crackling when playing Super Metroid with MSU-1 in an emulator (tested using Snes9x).

probably it exceeds the speed core supports.

Try and disable this option if it's turned on --> https://github.com/MiSTer-devel/Main_MiSTer/blob/master/MiSTer.ini#L9

On some displays I've heard crackling when this is turned on. Some kind of compatibility issue.

I tried enabling and disabling this setting, but it did not make a difference.
