When I play direct to laptop speaker I only have to press PLAY once. When connected to my network streamer I often have to press PLAY twice (also sometimes if I jump to the next track). When I press PLAY the second time I get initialising audio devices message.
Can you send me a copy of the “Debug Info”? You can get it in Audirvana Settings>General>Debug Info
Note: By clicking on the Debug Info Audirvana button automatically copies all its content, all you have to do is paste it in response to this message
