Try "model=hp-dv5".  After changing the model parameter, reboot once,
and check whether the module parameters are really set properly via
/sys/modules/snd_hda_intel/parameters/model.

Double-check the mixer elements all adjusted and unmuted.  If it still
doesn't work, post with the attachment of alsa-info.sh (with
--no-upload option) output with model=hp-dv5.
