Comment (by ilia_2s):

 I continue my experiments, but it's it is difficult to obtain identical
 results in each test o_O!

 I change Profire settings in Mac OS console to 44.1 for both standalone
 and hosted mode. If I remember correctly this settings is default. Now I
 can sometimes run FFADO at 192 khz! The playback causes a lot of XRUNS and
 crashes FFADO immediatly, but I can record a clear sound!

 With regard to RXs. If I understand correctly, RX1 uses only for receiving
 SPDIF channels. In previous log ffado's Rx0 contained 10 channels, that
 probably is not true. We also added a timeout for wait a samplerate (and
 ch/rx) changes. But now my new log contains this:

 {{{

 }}}

 I don't know why this happened after change samplerate to 44.1. I attached
 a full log. Possibly this can help. Also in this log FFADO crashes in the
 end for no apparent reason.
