Recalbox 8.1 now dreamcast roms launch but audio crack :(

[rgbfr]

Do you know how to fix sound issues or improve performances on dreamcast emulator?
Before 8.1 updates, roms like Bust a move 4 (cue) doesn't even work but now it's fine. It's almost good but the sound is cracking at least every 5 seconds.
I have a raspberry pi 4 2Go with libretro flycast
What do you think the problem is?

Thanks

What do you think the problem is?

It could be the ROM, it could be the ROMSET/file format, it could be the videomode....
Check these possibilities.
