Public bug reported:
No sound device detected during boot.
Searching for the problem showed that the sound card is not working.
When searching for packages, I found an update
Unpacking firmware-sof-signed (2.0-1ubuntu4.6) over (2.0-1ubuntu4.5) dated
2024-03-16 08:10:06.
Replacing the firmware-sof-signed package from 2.0-1ubuntu4.6 to
2.0-1ubuntu2 resulted in the sound returning.
