@aschiller: The Autostart Bluetooth tool of Max2Play is directly connected to the Pulseaudio process that handles the bluetooth connection. When a stream is sent to Max2Play it should instantly start in the Squeezebox Server and the delay should only be because of recording, buffering and streaming to the choosen Squeezeplayer. Following your description, I think the reason might be the device you are streaming from. When it starts playing, do you miss the first 14 seconds or is it playing from the beginning? Do you stream some local content or from an internet source?
Does it also take 14 seconds to stop in Squeezebox Server after you stop streaming?
