Where is CamillaDSP "Devices" configuration stored?

[Tim Curtis]

I don't know why it's reverting, maybe camilla has to be restarted after manually editing the yml file? You might want to ask in the CamillaDSP thread at diyAudio.

The Output device can only be changed via the WebUI because there are many parts of the audio config that are updated when this changes. Have a look /var/www/snd-config.php.
