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 
effectively useless.

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.
