I was trying it with Bose QC35 headphones.
It was 0.3.18 and as I say it was showing up as a device but
with no node that I could route audio to.
Maybe an extra step is required for that Bose QC35. Try to forget that device and
reconnect.
That configuration you attached still seems to be missing the
extra "-e bluez5" on the pipewire-media-session line? or is the
comment there wrong when it says that is required?
I haven't needed to put "-e bluez5" as Galaxy Buds+ worked without
extra configuration on a first try.
