Fbalpha cores not getting not sound

So i’m trying to to use fbalpha to run some my roms to finish my arcade build but i’m getting no sound. I tried all the fbalpha cores and several verions of retroarch and nothing. Any one have any ideas?

Most likely you picked a random rom on internet without a care about romset version : pick a specific core version (avoid the various fbalpha2012 cores expect if your computer is slower than a rpi3) then pick the right romset for it.
