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. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5461 8ced0084-cf51-0410-be5f-012b33b47a6e
