Stable version and latest HG version have problem with audio capture on linux.
Solution for this is very easy, just to rise input latency to something more realistic in inputdev_audio.cpp
set fixed value
inStreamParm.suggestedLatency = 0.08;
or set multiply of pdi->defaultHighInputLatency
.
inStreamParm.suggestedLatency = pdi->defaultHighInputLatency * 4;
defaultHighInputLatency*2 is also OK for my computer.
Need more testing on other OS
