I have no sound at all. By starting e.g. VLC or Audacity with a

Have you tried running jack without realtime priorities?

   jackd -r &
Are you (or Stretch by default) set up for realtime? (I don't know.) 

  /etc/security/limits.d/99-realtime.conf
  @realtime   -  rtprio     99
  @realtime   -  memlock    unlimited

  sudo groupadd realtime
  sudo usermod -a -G realtime yourUserID

Logout and back in.

I didn't read through the thread with much care, so maybe I'm in left
field (where I hope nobody pulls any line drives).


Hi Curt!
To your second question I say, I think so. Here is no group called realtime, and hence no file 99-realtime.conf in /etc/security/limits.d/. But there is a single file audio.conf and also a group audio, which I am a member of. The file contains the lines you mention, except the number 95 instead of 99, and "realtime" replaced with "audio".
On the first question I must say: I do not know. I tested your proposed command and got as a result a printout from jackdmp, which looked like a help printout.
