Odroid C2 No HDMI Audio / Slow kodi video performance

I installed DietPi_OdroidC2-ARMv8-Bullseye.7z in a sandisk extreme 32gb sdcard for my Odroid C2 board and there’s no hdmi audio.
I’ve been trying to fix it by myself, but my knowlegde is very little.

There are some messages I found may help:

Setting up alsa-utils (1.2.4-1) ...

This is aplay -l output:

root@DietPi:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: GXSOUNDCARD [GX-SOUND-CARD], device 0: fe.dai-link-0 (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Also, I think gpu acceleration is not working properly.
Are the drivers ok?

Kodi running output:

root@DietPi:/var/log# kodi
failed to open zone.tab
libva info: VA-API version 1.10.0
libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
sh: 1: nmblookup: not found

It runs and performs ok in menu, but once I load a 480p file it stutters a bit.
I didn’t installed anything else except kodi (using dietpi-software).

Thanks in advance
