VN7-591G - Realtek ALC583 Audio Chip

I am trying to locate the specifications for the Realtek ALC283 audio chip in my laptop. There are no specifications available in the Acer manual or on the website, and the specifications are not available on the Realtek website or any other online site that I can find. I have called Acer support, and after being bounced through about six Acer 1-800 numbers, as well as online chat, no one has been able to provide the specifications for this audio chip.

 

Any help appreciated.
