Narc rev. 7.00, rev 3.20 and rev 2.00 on MAME (Recalbox 6.0) - Sound issues

[teufelskrapfen]

Hi,

I‘ve been trying to get Narc run on Mame for the last couple of days but always getting sound issues ... mainly the music will just be a crackling mess.

I use a Pi 3b+ in combination with a USB Soundcard attached to it.

Ive tried all the versions i could find online (7.00, 3.20, 2.00) and i‘ve tried MAME 2010, 2003, 2003 plus, 2000 with all of them but always getting sound crackle..

I also tried some of the fixes suggested in other forums and dialed down the sample rate to less than 48000, changed the resample quality, turned off syncromization ... but none would work.

Does anyone have a hint what i can try?

Thanks Gregor
