This is obviously from the very old alsa-driver version.
Double-check whether the installation was correct.

Also, please attach alsa-info.sh output (run with --no-upload option) 
instead of uploading to a server.

Anyway, try the very latest snapshot (as of today).  A few new fixes
for HD laptops are there.  And remove all module options for
snd-hda-intel once.


HTH,
