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.
