This removes some bad behaviour, like the audio thread busy waiting inside ALSA code,
missing begins of voice samples(due to DSP_HLE code not getting called often enough).
Turns out my understanding of ALSA API was lacking.
Tested with pulse plugin and directly on my intel-hda/realtek hardware.

The fix is asking alsa for a prefered "hardware" buffer size, so alsa does not fall
back to pulseaudios offering of ~1 minute. Additionally, alsa busy waits when pulseaudio
is used, sw:avail_min is set and hw:buffer_size is small.
