Support for 8086:ae20 Intel Smart Sound Technology on Fujitsu Lifebook
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,

I checked in our internal sources and while I do see a 'DMIC_DEVICE_ID' 0xAE20, this is not related to PCI and that's not what is used to probe a driver.
if you are looking at Windows, the string you want to look for starts with 'CTLR_DEV_', not 'DEV_'
Now the interesting thing is that booting into linux and using lspci and lsusb, I cannot see a single device with the above specifications:

Dear Pierre-Louis, dear all,

Thanks, didn't know. The string I found is CTRL_DEV_02C8

When I check with pavucontrol I only see Built-in Audio Analog Stereo as input source, and there is no reaction to sound (and it is unmuted). So I guess this is the device connected to the plug on the side of the laptop.

[~] cat /sys/bus/pci/devices/0000:00:1f.3/device 0x02c8
so that's CometLake LP

this one means the audio DSP is enabled, but might not be required for your platform.

and this means the kernel did not detect an interface that requires the DSP.
Looking at your alsa-info log, an alternate explanation is that your distribution forces the use of the
snd_intel_dspcfg: dsp_driver=1 option, which will select the HDaudio legacy.
If you happen to have a device with microphones attached to the PCH, not the HDaudio codec, then by design you *cannot* use the legacy HDaudio driver (snd-hda-intel). you will have to use the SOF driver (snd-sof-pci-intel-cnl).
Can you check in /etc/modprobe.d/*.conf if you see a configuration that sets this module parameter?
If you see this option set, try to comment it out and reboot. You should really avoid setting the dsp_driver option since it will bypass the autodetection and might result in the wrong driver being used.
Hi Pierre-Louis,
snd_intel_dspcfg: dsp_driver=1 option, which will select the HDaudio legacy.
Bingo! I carried that over (without thinking) from my previous laptop (lenovo where it was necessary).
Removing the modprobe.d file, *and* installing the firmware files helped.
Now the device shows up and everything seems to work. Puuuh.
Thanks a big lot for your help, that is much appreciated.
Sorry for the noise, and all the best
Norbert
