I can play music out of either one separately using Bluetooth but when I hit the play all button it sits there like its going to for a minute and then goes back to just playing from one. What am I doing wrong?
Can you check the signal strength going to each system? HERE are the steps to do this. Ideally we would like this to be at "Good" or "Excellent". Does this issue happen if you start the Bluetooth stream from either system or just one of them? If you haven't tried to start the audio with the other system, let's see if that helps. Starting with the system that has the strongest signal is best. Can you try to unplug your systems from power for 30 seconds and re-test? Can you also try to power cycle your router?
