I want to use my Raspberry Pi 3B+ running Raspbian Buster to receive audio from my phone via Bluetooth. Next i want to process this audio with Stereo Tool and output it through the on-board audio jack.
I managed to get the audio routing from a media player to Stereo Tool working using jackd. (Stereo Tool only supports jackd, so I guess I have to use ALSA because I can't use PulseAudio).
Also I got the Bluetooth audio receiver to work, but only in mono! (Using this tutorial) Is it possible to get stereo sound?
The next thing I want to do is route the received stereo audio to Stereo Tool using Jack, and then output it to the on-board audio jack.
Can someone help me achieve this? I'd be very thankful!
