Hi all,
I'm forwarding a Bugzilla report [1], as many developers don't take a look
on Bugzilla. The reporter (Lukas Voreck <[email protected]>, Cc'ed)

I hope I'm responding correctly
On bugzilla I was asked to attach dmesg and lspci output. I'm sending both as attachments (cause of their length) and hope it works, it's my first time working with these mailing lists.

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.
HTH,
Takashi
