Good job, BBH. Yes, your recording now plays back perfectly for me when I use "-noym3812opl".(posted 9298 days ago)QT: My guess is that even when you specify the soundcard through MAME (and I guess that both have an SB interface), MAME still has to look for the soundcard. I guess it just happens to find one of them first, and so it never looks for the other one anymore. Is that second one an onboard card? If so, and if you don't want it to be used ever, then you can probably jumper something on your motherboard to disable it.
Cheers, Ben Jos.
