curious, how did you end up dumping these?
Mentioned it a while back, I think: There was a module called "InstallPchHdaVerbTablePei" in the vendor firmware. I found the verb tables as a blob of data at its tail. Expanding the init_pin_configs using the AZALIA_PIN_CFG macro gave the first entries in the table; the below are the rest.
If you're looking for similar settings yourself, I'd recommend using UEFITool to search for known entries - the reset verb, for example. Of course, I know that I was slightly lucky: both regarding the name of the module, as well as the fact that the table wasn't encoded in any way.
I will elaborate slightly on the comment (here and anywhere else). How about "Undocumented settings, see data blob in "InstallPchHdaVerbTablePei" of vendor firmware?"
