Actually that was my motivation to write the JACK OP in the first place.

if jack is running as the main sound system it, will have lock the alsa
device*, so the alsa OP init should fail. jack OP should then success so
after alsa ist the right priority in this case.

However, the jack API will per default try to autostart jack if it is
not running. For people relying on this the "right" priority would be
jack OP before alsa OP.

Im going with the first use case: alsa OP then jack OP.

* it could be that jack outputs to pulseaudio or some other sound
server/API...
