Tank you for the tip, speaker-test worked for my Hercules so i thout
should work for intel too. So with tiwai.git and -Dsurround51 or
surrounf71 outputs are working. Bad the mixer map is in really bad
state. Here is my current investigation, here are the controls i tested:

[jack]  [surround]; [mixers;...]
green - front r/l;Master; PCM; Speeker 0;
blue - side r/l ------- PCM; Speaker 3;
black - rear r/l; Master; PCM; Speaker 1;
orange - cenrat f/r; Master; PCM; ------; swap;
('Swap Center/LFE Playback Switch' (change front and reare outputs))

You can see - master control not all jacks and most (not all) jacks have
own mixer.

'Master Playback Switch' <- master but not for all (blue jack not
contr)	
'Master Playback Volume' <- master but not for all (blue jack not contr)
'PCM Playback Volume' <- bad sound if too lo
'Center Playback Switch' <- not working?
'Center Playback Volume' <- not working?
'LFE Playback Switch' <- not working?
'LFE Playback Volume' <- not working ?
'Speaker Playback Switch' <- Front Playback			
'Speaker Playback Switch',inx=1	<- Rear Playback
'Speaker Playback Switch',inx=3	<- Side Playback
'Speaker Playback Volume' <- Front Playback
'Speaker Playback Volume',inx=1	<- Rear Playback
'Speaker Playback Volume',inx=3	<- Side Playback
'Swap Center/LFE Playback Switch'<- order switch ?or route?


I will continue to investigate this board.
