So I've decided to try mplayer. List of tested cases:

mplayer -ao alsa:device=hw=1.7 Canyon-5.1-48khz-448kbit.ac3 -channels
6 -srate 96000
mplayer -ao alsa:device=hw=1.7 Canyon-5.1-48khz-448kbit.ac3 -channels
6 -srate 176400
mplayer -ao alsa:device=hw=1.7 Canyon-5.1-48khz-448kbit.ac3 -channels
6 -srate 192000

mplayer -ao alsa:device=hw=1.7 Broadway-5.1-48khz-448kbit.ac3
-channels 6 -srate 96000
mplayer -ao alsa:device=hw=1.7 Broadway-5.1-48khz-448kbit.ac3
-channels 6 -srate 176400
mplayer -ao alsa:device=hw=1.7 Broadway-5.1-48khz-448kbit.ac3
-channels 6 -srate 192000

Rear right and real left were always working fine.
The rest (front  & center & front) were working for 96000 only.

So it seems to be some issue with my Onkyo TX-SR605 that reports
support for 192000 but can't fully handle it. Weird :|
