ALSA: hda - Apply ALC269 VAIO fix-up to all Sony laptops with ALC269 We've applied a fix-up for ALC269 VAIO only for two models. But all Sony VAIO models with ALC269 codec seem to require the similar fix. Let's apply it with vendor-id mask.
Does it mean that the Fixup need to check whether node 0x19 must be valid Mic pin if Sony Vaio pro 13 alc286 does not use node 0x19?
Yeah, that's a valid point - we should try different vref values for pin 0x18 to see if any of them works to enable headset mic (and possibly also get rid of the noise in headphones).
