Bluetooth headphone/speaker connecting but no sound

I bought a Fairphone3+ with /e/ on it (android 10). All works fine, except for bluetooth. Everything connects like it should: Jabra 65t, Marshall headphones, Eneby 20 IKEA speaker, Panasonic car radio. A wide range of connections I’d say. It will connect, I can set it to send media to it (so it’s not the obvious setting) but the music still comes from the phone speaker, not from the device. Making a phonecall works, it is just sending music to bluetooth that doesn’t seem to work.
I’ve seen some other bluetooth issues with Android 10 and bluetooth, and sometimes also with FP3+ and bluetooth, but I don’t think I’ve seen this problem in particular. Or maybe I haven’t been looking long enough. Anyone?
