Hi Stefan, I'm also having sound problems on some of my machines but not to the extent of hearing just burpy noise. It's more like having the normal sound plus some cracking (sometimes a lot, sometimes only a little). I'm still investigating, might be similar to the problem with mplayer and libsndio seen on this list recently. I can make it go away using two different ways: - not using libsndio: env SDL_AUDIODRIVER=audio sdlmame ... - run an aucat server If this doesn't solve your issue, here is a few things to check: - make sure you running at 100% framerate (but this game should not eat much CPU). If you're not at 100%, you could tweak video settings to improve the framerate (e.g. using -window -nomaximize). - AFAIK sdlmame uses 48000 Hz as the default sample rate, maybe your sound card doesn't like that (but it's usually the opposite). It can be changed using the -sample option.
