Thanks Marc - I got it working with these links; installing the
pulseaudio-module-jack package mentioned in the first link, then
preparing the scripts launched by qjackctl in the second. Pretty sure
that's what I did. I also used the .asoundrc as given in my original
post.

I was just faced with this challenge myself (don't ask).

I found that switching sinks with PulseAudio was unreliable. I opted to use the ALSA loopback device combined with Jack1's "new" builtin support for Fons' zita-based adapters for any number of additional ALSA devices.

I've been using it all day, and it works really, really, really well. Much more reliable than either the ALSA Jack plugin or switching Pulse sinks.
