Reduce choppy sound on audio playback if audio sink is almost empty
If audio sink buffer is almost empty, that happens on pause/play,
the sound pretty often has little gaps. The solution is using some
little samples compensation (slows down the playback on 1% for
1-2sec what allows to increase buffer loadig from 0-10% to 20%).
In other words, the patch implements slight "soft" audio samples
compensation in order to avoid having empty adio sink buffer.
Pick-to: 6.5
