I thought very long, that it don't support JACK. But I just ran ldd, and saw a
dependency on libjack.so.0. And if I try to playback when jackd is not runing, it says,
that could not connect to jack server. If server is runing, it doesn't produce any
signals, but silently prefers alsa. I have JACK2 and tried both with jackdbus and legacy
jackd. So, what is situation?
I assume, it is undocumented and half-complete feature, but it is interesting, to have an
expert opinion. I could not find any helpful information about.
