afaics, you can use hw:SHORTNAME instead of the usual hw:NUMBER form, 
but that only helps if you can distinguish device names by their 
respective short-name ie. different device brand models.

device short-names maybe read from /proc/asound/cards, being the names 
found between [] brackets.

otoh, ~/.jackdrc is optionally rewritten by qjackctl, as seen convenient 
to replicate its settings when auto-starting jackd later, eventually 
outside qjackctl control.

nb. qjackctl never reads from ~/.jackdrc.
