Great stuff again Len. Thank you. I now have a file in /etc/modprobe.d/
called blacklist-hdmi_sound.conf which contains:

blacklist snd_hda_intel
blacklist snd_hda_codec

Now aplay -l just lists the two RMEs, which is just what I wanted.

I've also had more success modifying the JRigg .asoundrc, to the
extent that qjackctl now shows all 52 channels as r/w clients in
the connections widget.

I won't be needing quite so many output channels, so I'll probably
use the separate in/out configuration as demonstrated in the JRigg
article. It's currently an all duplex config.
