I should have mentioned that jack-play is in the jack-tools package.
You also get jack-transport, which would save you having to put the
delay in your line. You would be able to start jack-play first, with
a -t in the command line to make it transport aware. Then make the
links and then use jack-transport to play, stop, locate, etc..

Or you could use jack_transport, which may be installed (it isn't
part of jack-tools, so I'm not sure what it came with).
