adding of pthreads; that's all gone now, it sucked.
- Add a libao sound output, this has been mostly tested:
- it works with wav output on my powerbook (where oss out
is broken)
- it works but sounds really jumpy when playing 44100Hz
samples through a shitty onboard soundcard that only
supports 48000Hz output... the dma buffer gets played
too fast.
