I just want to say “Thank you” to everyone involved. I got the lappy_mctopface.json, loaded it into easy effects, created a “default” (empty) one, set the auto-loading of output presets based on the output device, and it’s all perfect now and I don’t even have to think about it.
The quality is much, much better then it was before. I mean - these are still laptop speakers, but they sound decently for what they are.
