Bug Description

See https://ubuntuforums.org/showthread.php?t=2502377 for detailed information:

In short:
Fresh install of 24 LTS causes internal speakers of Laptops with Intel WhiskeyLake-U (i915) to not recognize the Hardware/Sound Sink.

This issue was not existing up until 22 LTS with using PipeWire/Wireplumber (maybe Ubuntu 23 works too, I never tried).

Even when upgrading from 22 LTS to 24 LTS the issue persists, so it clearly is with the Kernel Packages for Firmware/Modules.

Opening f.e. Alsamixer, the HDA Intel SND / Realtek ALC236 is recognized. As the internal Microphone works as Source, I am baffled why the internal speakers as sinks wont be recognized.
