There are recent additions to apply the static configuration for such
machines with broken BIOSen.  For HP, it'll be included in 6.8,
currently found in for-next branch (or topic/cs35l41 branch) of
sound.git tree.

You'd need to adjust the quirk tables in both
sound/pci/hda/patch_realtek.c and sound/pci/hda/cs35l41_hda_property.c
to match with yours.
