after spending the last couple of weeks trying to connect my bluetooth soundbar to my Raspberry Pi 3 B+ and playing all audio output on it I am close to giving up.
Using the GUI I can successfully connect the soundbar and I can also set it as the default audio device. YouTube audio plays perfectly on my soundbar and I also tested successfully with bluetooth headphones.
Using bluetoothctl I can also pair + connect it via Shell; however I have no clue how to set it as default audio device by using a shell script.
It seems there have been changes in the past versions of Raspbian and PulseAudio is not needed anymore and BlueALSA is the most recent solution. Most tutorials I found are still referring to PulseAudio.
Basically all I need to know is how to programmatically change the audio output device to this specific bluetooth device, without having to use the GUI, since I want to automate this step. After all is done I want to switch back to HDMI audio output.
uname -a tells me my current version is 4.14.98-v7+. I just reset + updated my RPi to make sure it's a fresh install.
Does anybody have a clue?
Thank you very much in advance.
