I’ve been trying unsuccessfully to get Bluetooth audio to go from my phone to the pi through the speaker connected to the pi (I have a speaker connected using a 3.5 mm audio cable). The pi will play audio just fine and I have the Alexa app on it working well.

Because Amazon has prime music disabled the next best thing is to be able to play music through my phone through the pi.

I am running stretch, with the Alexa integration and the magic mirror app with a pi 3. It has the built in bluetooth.

I followed these instructions:

I can connect and I can see through USB activity that it’s streaming over to the pi but I cannot figure out how to get it to output the sound to the speaker. I’ve gone through the audio settings several times but it all looks correct.

Has someone gotten this working who can share with me how they did this or have any theories on what I’m missing?

Thanks!
