Dear all,
(please Cc)
today I realized that the built-in microphone (next to the webcam) of my Fujitsu Lifebook U-series is not detected. (I usully use a headset, but due to travelling was forced to use the internal).
I tried hard to get this device working, but neither with my self-compiled kernel (5.15.6) nor the Debian kernel distribution kernel 5.15 the microphone seems to be detected.
I booted into Windows and tried to find out what the device might be. My **guess** is what is mentioned as Intel Smart Sound Technology with Vendor ID 8086 Device ID ae20 I git grepped the kernel sources for this, and snd-hda-intel contains quite some mentioning about Vendor ID 8086, but ae20 is not appearing.
Now the interesting thing is that booting into linux and using lspci and lsusb, I cannot see a single device with the above specifications:

I attach the output of alsa-info for completeness. The kernel version is 5.15.6 with some patches from xannmod, but I could reproduce the same behaviour with standard Debian kernel 5.15.
Am I missing some config option, or is the vendorid/devid not supported by now?
Thanks for every suggestion,

Al the best
