On the Baytrail platform with ALC262 Realtek Codec, HDA Audio is enumerated as PCI device 00 1b 00,

the verb table is being programmed on HDABAR + command offset. 

Using uefi Payload which has PchInit -> DetectAndInitializeAzalia, there are no Errors in this path, all looks good

Either Beep or Audio speakers fail to work in EFI Shell and also in Ubuntu

aplay -l does not Audio ALC Codec as sound card 

what is missing to enumerate, FSP path\SoC Straps are enabled for Audio so they seem to be fine too

Appreciate for any clues to make HDA to work on a BayTrail Platform

Thanks
