What happens if pulseaudio is running and using the sound device?  Can
qemu open and use the device in parallel?  "in-kernel mixer" sounds like
this is works and the kernel mixes the streams from all applications
before sending it to the sound device.  Or will qemu get a -EBUSY?

If parallel usage works we can default to oss I think.  Otherwise we
should try pulse first, and in case it is not available (daemon not
running) try oss next.

What about sdl?  Prefer oss over sdl I guess?  Or the other way around?

What is the native sound interface for openbsd btw?  oss doesn't
compile (missing sys/soundcard.h header).
