Now driver support most of CODECs. I don't know cases when specific
CODEC would be a problem, and Realtek CODECs from functional side are
better then many others. But many systems have custom wiring and laptops
are usually more problematic there.

As I see, these three hints are replicating existing configuration and

CODEC configuration looks good and I see no problems in driver output. I
think most likely problem is in CODEC wiring and power amplifier. Your
CODEC has two GPIO lines and EAPD line. That gives 8 possible
combinations. I would recommend you to try them all. GPIOs, as you tried
could be set with hint.hdaa.0.gpio_config tunable. EAPD line can be
controlled (0 or 100) by the ogain mixer control.
Unluckily with this output I can't completely identify your system to
check what Linux does for it. Could you send me `devinfo -vr` output.
