Newbie setup of Amiga Emulation

[flac_rules]

I bought launchbox a little while ago, and I am trying to setup some systems, most is pretty easy to setup, however I am struggling with with an old favorite of mine, the Amiga. I tried this collection https://forums.launchbox-app.com/topic/52912-fully-launchable-whdload-collection-dec-2019/. It uses WHDload, I haven't used it before, and I am not actually 100% sure what whd-files actually is (a hard-drive version of the floppy images?) the problem is that with the collection setup things works in the sense that thing launches, but the music is choppy. And the game also seem to be a bit choppy (although i don't quite remember the framerate on the original hardware). What am i doing wrong here? My computer is reasonably powerful (and 8-core and a 1080 gtx) and emulates everything else I have tried fine. Seems strange to me it should struggle hardware-wise with an amiga. Should i set it up another way? is whd the way to go? I remember dabbling with amiga emulation many years ago, and the performance was fine then (with disk images and WinUAE), but it was always a real hassle that some hardware setup worked on some games, and not on others.
