This is exactly the problem. Rates are equal, but there are over/underruns,
even in simple "audio source -> audio sink" graph.

Does it mean that I will not able to run in realtime simple graph with
48kHz signal source, Qt GUI Sink and audio sink on modern computer ?

No. Read my first post.

Thanks. :) While hacking seems to be interesting, I prefer professional,
official supported and documented approaches.
