That looks easy to try and it runs OK without much complaint:

$ /usr/lib/carla/carla-bridge-native internal "~/Wed-tune.wav" audiofile
libjack.so.0 loaded successfully!
Previous plugin state in '/home/john/Audio File.carxs' is non-existent,
will start from default state

But no sound. It shows up as a Readable Client with the right name,
which I connect to playback_1 and _2 (and ebumeter), but nothing
(with Jack transport running).

Thanks again, John.
