Today, I ask for help getting the built-in audio to work on my HP ZBook 17 G6 with nVIDIA T1000 gfx/audio sub-system. The built-in audio system was tested and found functional using the BIOS/UEFI (01.31.00) sub-system test. The system is up-to-date on the latest Fedora-41 updates (kernel-6.13.7-200.fc41.x86_64). The HDMI audio output is fully functional. pavucontrol only shows the “HDA NVidia” device. To make sure there wasn’t some left-over wireplumber configuration, I ran Fedora-41-xfce-Live from USB drive, which also did not “find” the built-in audio.
Some pertinent system information:

I have had the HDMI plugged into a tv to confirm that the HDMI audio is functional. Plugging that in and taking it out again, did not add devices to the pavucontrol (as apparently it did for some others).
Your suggestions towards getting the built-in audio to work will be highly appreciated.
