So you're saying the use of sdl for audio is not recommended?

Thanks for the clarification.

With this INT 10h function qemu should beep once, but it does loop the beep infinitely.
Normally i can exit qemu by clicking on the [x] window close "icon", but while it does
endlessly beep that doesn't work (vista says process doesn't respond). Using "quit" in the
monitor window doesn't work either.
