Linux 6.8.2 patch 10431A63 - UX3405MA.304 Sound CS35L41 Workaround For context: In bios version 304 pretty much all the config is present (confirmed via dumping and looking at ssdt16), except for "spk-id-gpios".

@paul-ri Thanks!
Will also test when it lands, to me upstream requested patch looks good.
