It gets "No object received" when trying to register the BAP
application, so probably the LC3 codec is missing somehow.

meson setup should have reported 
"Bluetooth audio codecs ... LC3 : YES".

`ldd install/bin/pipewire` should link to libpipewire-0.3.so.0 under
the install/ prefix and not to system lib. If not, the rpath in
compilation accordingly should be adjusted accordingly, or set
LD_LIBRARY_PATH there.

Also the codec plugin 
install/lib64/spa-0.2/bluez5/libspa-codec-bluez5-lc3.so should exist.
