>> >> Have you tested surround21? > > Yes, front speakers work fine, however LFE doesn't seem to work. Instead when I try to test LFE (from sound UI) I have weird noise in one of rear speakers. There are no such problems with any other mode though (I see that officially only 5.1 mode is supported, however 4.1, 5.0 and 5.1 all work fine), I decided to leave 2.1 mode for now, not sure whose fault is that.
