I have still not managed to get sound out of my Echo Dot, although to be honest I don’t really know what I can do to debug it. I’m still in the position where LMS looks like everything is fine, with the progress bar and count up/down timers all behaving properly, and the Bluetooth still showing connected – but gettin no sound output.
To test the Echo, I have used an old phone and SB Player for android. This setup worked out of the box, which means that the Dot does at least support the feature. This does also mean that I can now use it as the house automation announcement speaker that I wanted.
Is there anything I can do, or try, to help fix the problem with the M2P plugin?
