My last answer may have been confused. I have had another problem starting Jack, which I have a workaround for. Just the last time I tried it, I believe that was stopping me. Now, after clearing up that problem - by removing /var/lib/jack/tmp/jack-500/default/jack-ack-fifo* files, and rebooting, I found that jack will start as well as it always did, waith the original settings. However, I was fully aware of this problem, and it wasn't happening earlier - it's a different error message (which I didn't spot this time, because I was suppressing stdout...) Anyway, my system is working fine, but I am not aware of anything that I have done differently this time. I tried all of the same things before. Thanks Michael
