I have no answers on those questions.
> 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.
> Do surround51 works since you have a hardware volume knob but PCM 
> playback volume is mono
If I understood you correctly - I've took mono sound (wav from ALSA 
package) and played it through VLC, all channels work as expected.
> Do it mean that headphone can auto mute  speakers connected at rear ?
No, Rear, Center and LFE still working.
It feels like there is simple mechanical switch, because while I'm 
slowly inserting jack at first right front speaker turns off and then 
left, I guess otherwise they would turn off synchronously.
