Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
This may be something you know already, but it sometimes helps in cases like this:
With a Bluetooth audio connection, first you
the two devices, then you
the two devices, then you hopefully can play through the connection. In a case where playing seems not to be happening, and you have already made sure you are both paired and connected, you sometimes need to adjust the volume upward a bit (either on the playing device or on the device with the speakers on it), or you may need to un-mute the playing device.
In this case, since I think you have a Jandy device, usually they have a Remote control, and you can adjust the volume upward for the speakers with the Remote. If you are playing music through a handheld device, you may need a Jandy app for the handheld device, to play to it properly.
Let me know more about the handheld device you are trying to use. Thanks.
