Please check our LMS Bluetooth feature. You do not need to use pulse as output with this solution. you can find it at the bottom of the Bluetooth Plugin menu:
Setting up Squeezebox Server to stream audio via Bluetooth to multiple connected players is easy too. This only works for the Squeezebox Server running on this device! Make sure to have your smartphone connected successfully and click the install button below.
Afterwards, you see the „Bluetooth-Player“ in your Squeezebox Server favorites and it will play automatically when you start streaming from a Bluetooth device and switch back once finished streaming!
