I remember it worked once, but since 5.0 can replace 4.0 without any
difference I've removed it now from config.

Me either.

> How many profiles supported by omni ?
I've tried to find something already and didn't succeed. Currently in
sound settings I can choose between Stereo, 2.1, 4.1, 5.0 and 5.1,
Stereo on S/PDIF (surround was not supported here, however images on
official website show that is should). There was 4.0 in past, but
currently it is not present.
Funny thing is that even when S/PDIF chosen it still play sound through
Front/Headphones, can't check how it will work with real S/PDIF, also
S/PDIF volume is actually not absolute, but fraction from Analog Stereo,
not sure how it happens, but I had the same with other USB sound card
even without S/PDIF (Plantronics GameCom 777), it is like phantom output
on every card and works in similar way. I can remove S/PDIF, but there
is a chance that it may work for others.
