LibreElec 12 changes sound output after using Moonlight

Hi,

LibreElec changes sound output after using Moonlight.
I'm using a laptop with a usb-c -> HDMI adapter plugged into a tv.

Ryzen 5400U with LibreElec 12 installed and “Arctic Zephyr” theme

I configure the output to the DP adapter, then when I quit moonlight and come back to kodi I no longer have sound.

Try the Audio Profiles add-on as workaround.

Where can I found it ? And what is here name ? Thanks

Kodi Add-on repository -> Program add-ons -> Audio Profiles

Documentation: Add-on: Audio Profiles

Thanks, bu it doesn't work, I installed the extension, put the correct output, saved on profile 1 and I applied the same profile for all codecs and "Profile for GUI", "Profile for an unknown content type " etc ...
It doesn't change anything, it goes back to the HDMI output, so the profile was not saved

EDIT:
To give more detail, it changes profile on films and series, but on moonlight no (it's a docker container)

I guess profiles don't apply on docker and neither does AC3 transcoding.

Sorry to hear that. Try to avoid the USB-to-HDMI adapter:

Sometimes audio output options change after HDMI firmware update. Maybe you can use DP for A/V afterwards. So if you can run Windows somehow, install the latest HDMI firmware, and see what it does to your DP output.

The cable is already up to date, it's this cable.
I had no problem with version 11 of LibreElec (not on the same PC though)
