Hello,

Hi, Theodore,

I assume that someone is already working on this but I do not know who. I have some experience with coding and kernel stuff (see drivers/media/usb/gspca). Not experienced with doing sound support.

There's a Windows driver for the ESSX8336, isn't there? What I'd do is I'd pull out Ghidhra and try to reverse engineer it...

If you choose to do it this way, be prepared to spend long stretches of time elucidating what struct is that pointer math pointing out to, etc.

Once you have plugged in all necessary information into Ghidhra, that will surely be missing because the driver most likely was stripped of debugging symbols, you'll still have to port it from Windows to Linux.

Nightmarish for sure, sorry if I can't propose an easier route.

Thanks, Geraldo Nascimento
