I am running LibreELEC on a Pi 3b+ hooked up to my audio system via a usb cable. Now I tried out the integrated AirPlay feature of Kodi and it works great, but it‘s very delayed. I know that AirPlay ob Kodi works via Shairport and that I can change the delay (as Buffer Size) in the Shairport Config file. But I don‘t know, where this Config File is located.
