I've been using Libreelec9.x on a Raspi3. I installed a Hifiberry for audio output. Everything worked great.
Now I've updated to Libreelec12.2 (complete reinstallation and also reconfiguration of the system). In config.txt, I entered dtoverlay=hifiberry-dac, as it was before.
After selecting it in the GUI, everything worked as it should. But after a shutdown or restart, the audio output is set to DEFAULT and I have to manually select the Hifiberry again in the GUI.
What could be the reason for this and how can I make my desired audio output the DEFAULT?
I have set up Aeon NOX - Silvo as my skin.
Thank you very much for your help.
