The Memeza laptop EDL03 with codec ALC256 can't detect the headset microphone. The headphone jack sensing works after we add a pin definition for it by ALC256_FIXUP_ASUS_MIC_NO_PRESENCE.

If the newer BIOS still doesn't fix the PCI SSID, you can check the codec SSID instead.
thanks,

Thanks for the feedback. This is a special case that the ODM didn't flash the DMI information and assign a formal SSID. They simply ship with the current status w/o any BIOS customization.
I agree that we should push the vendor for a BIOS fix or figure out a generic solution for this instead of a pin quirk. Please ignore this. Thanks
