Right. Here are the files that I have replaced in 3.11.7 tree:

*.orig
hda_codec.c.orig  hda_codec.h.orig  hda_eld.c.orig  hda_jack.c.orig
hda_jack.h.orig  hda_local.h.orig  patch_hdmi.c.orig

Sure, here is the output:

This is looking good. Maybe this is coming from how the channel mapping
is communicated to speaker-test through ALSA API but I don't know much
about that.

I'll try to understand as well on my side what is going on.
