Hi,
With the mainboard Asus Prime TRX40-Pro I do not have any on-board sound. I tried to fix it myself after reading here on the mailing list (thanks to Dan Aloni and Takashi Iwai) and with the patch below, I was able to partially fix it. The front headphone still does not work and I did not test the microphone(s) input. But at least I can hear sound when using the C/SUB, REAR and LINE OUT at the rear.
As mentioned, the patch does not solve all problems, but it is a little pass towards a system with working sound. The patch below was tested by me on Gentoo with 5.4.72 and on Arch Linux with 5.9.3. I hope, it will land in the kernel sources somehow. Please feel free to modify and use it. Because the real name is required, I cannot submit the patch myself.
Thank you for reading this and eventually considering to submit this to the kernel sources.
