The stream is set up to hp_nid (0x06) too, regardless of the
channel mode.  You can confirm this by compiling with
--with-debug=detect option that will show more debug messages.
So, it shouldn't be the problem of hp_nid but others.

If the no sound comes out, it means either pin is reset to input, or
a volume is muted in the route to DAC 0x06 -> hp-jack.  Check
/proc/asound/card0/codec#* after ch6 mode.  You can comapre the status
with ch6 mode, too, by simply diffing codec#* dumps in the different
states.

Thanks, but an uncompressed file would be more appreciated :)
