You may need to add the model=hp-dv5 parm to the snd-hda-intel module. There are a couple ways to do this. One easy way is to put the parm in:

/etc/modprobe.d/alsa-base.conf

Add the line, or, replace an existing model if there is already a different on indicated:

options snd-hda-intel model=hp-dv5

Options put in this way will take effect on the next reboot.

FYI my HP DV7 is an dv7-6c73ca.
