There's a Linux driver for the 878 sound blob.

The 878 datasheet is publically available too

Basically the device is divided into 2 logical parts. Function 0 is the video
side, and function 1 is the audio.
I believe you should be able to attach to each part independently, although
maybe it would make sense to make bktr all in one.
