System info:

  • Operating System: Ubuntu 22.04.3 LTS
  • Kernel: Linux 6.5.0-14-generic
  • Architecture: x86-64
  • Hardware Vendor: Hewlett-Packard

Audio card is not detected in system, this is indicated by the LEDs on the notebook.

I tried:

  • Build drivers from the Realtek website (No success)
  • Trouble with alsa
  • Something with alsa gui
  • Kill PulseAudio

and that's it.
