[1.] One line summary of the problem: No sound on HP Firefly 14 G9
[2.] Full description of the problem/report: Although the corresponding kernel module is loaded successfully and I can also see a sound output being produced on the software level (in gnome-control-center), physically there is still no sound coming out of the speakers. My HW card was identified with the code "0x103c" "0x896d", for which a patch was already submitted in the following commit: https://github.com/torvalds/linux/commit/f86bfeb689f2c4ebe12782ef0578ef778fb.... Unfortunately not working in my case. Also the patch identified the model as "HP Zbook Firefly 16 G9", however in my case the model is used "HP Zbook Firefly 14 G6" (14 not 16).

[X.] Other notes, patches, fixes, workarounds: I don't know by myself how to fix it - not sure what exactly is relevant on the HW side to be checked and how to patch it in the patch_realtek.c exactly. Would be glad if you could help me navigate here (what HW information should I look for) and would be happy to try to patch it and test by myself on my machine.
Thank you.
