I’ve booted into the test kernel (6.14.0-1005-oem) and can confirm that the internal microphone now works correctly without any manual model override in alsa-base.conf.
Thanks very much for the patch and support! Let me know if you’d like me to test anything further or help validate future builds.

On Ubuntu 24.04.2 LTS, the internal microphone is detected and listed correctly in PulseAudio/PipeWire and ALSA, but no input is captured. Microphone volume and boost are set to 100%, not muted.
