sure, everything as the same user...

Running this command kills jack after a few seconds, which was my original 
problem in qjackctl (before I created root-owned tmp files).  If this 
complicated...leave me to fend for myself..I can't thank you enough for 
all your help so far.

I've tried different bitrate, periods, buffer sizes. Any other frequency 
tells me there is a conflict between jack's freq. and the set (?) one
