OK, this suggests a problem with the loopback module.

What parameters are you giving to the loopback module? I see in the log:

source="bluez_source.C4_43_8F_9F_F5_36" source_dont_move="true"
sink_input_properties="media.role=music"

Is that all?

Try increasing the latency (default is 200), or disabling remixing.

If that fails, try changing the resampler in the configuration file.
