Manjaro arm on Amlogic Tv box?

Maybe g12a_sound.sh does not detect your soundcard correctly. You can then try the following:
(I am writing this from memory because I currently do not have access to my box)

  • Open terminal and then type: aplay -l
  • Copy name of your device to clipboard.
  • Now type: sudo nano /usr/bin/g12a_sound.sh
  • In the top of the script under the section where script tries to automatically detect card1 (ca. line 6-8) add: card1=“NAME_OF_YOUR_SOUNDCARD” (Ctrl+Shift+v to paste)
  • Ctrl + S to save and then Ctrl + x to exit nano editor
  • Now run /usr/bin/g12a_sound.sh again
  • Type: sudo systemctl enable sound --now
  • Reboot and pray!
