Fwd: Xonar DG pci sound card driver incomplete

[kernel kernel]

Requesting guidance on how to implement the missing mic input support
for this Asus Xonar card. I've downloaded the relevant datasheets but
am unsure how to proceed. I have physical access to this hardware. I
would appreciate a description of a workflow towards finishing this
driver or any other comments.

I believe the audio processor in question is the C-Media CMI8786 and
the existing driver is located in   sound/pci/oxygen.

Regards,

Ken

Rip out the card, and look (or eletrically trace) how the CMI8788's
GPIOs and the CS4245's inputs/outputs are connected.

Test how to configure and set the GPIOs so that the mic works.
Also check the register configuration of the CS4245.
