 Issue is fixed until first circular buffer underflow, after that it starts
 to wave again.
 Problem is with timestamps, they must be updated then buffer fillsup

 Another problem is with circular buffer overflow. In overflow case it
 simple exits. There must be implemented overrun_nonfatal option for

 I tried to fix it my self, my fix works well, but i'm not 100% sure that i
 did everything right.
