I guess it's ignored for 2 reasons :

1) N/Aconnection
2) Input from non-reported 0x3e widget

Nope. The sound path I got finally are :
08/34/14/24/00
08/21/14/24/00
09/3c/1c/33/00
08/35/15/25/00
08/21/15/25/00

So, front on 0x08, shared with HP, and subwoofer on 0x09. Volumes are on 0x08 and 0x09 controls,
afaik there are no more volume controls there.

I didn't retask the mic (0x2b)... just the 24 and 33.

Don't know.... if I let 0x33 and/or 0x24 as speaker, they're put as speaker out but not taken
in multiout paths.

As above, a volume control is shared between front (24) and HP (25) pins, I guess.
Volumes are present just at DAC level, not pins.
