[PlanetCCRMA] More JACK Problems

[Mark Knecht]

Fernando,
   There is something strange about this sort of problem. You may remember
that a few weeks ago I sent a message in to the Planet about some similar
stuff. It wasn't quite like Mike's problem, in that I could always start
Jack, but I couldn't play CDs using the -r option. I never really solved it,
but along the way, for other reasons rebuilt the machine from scratch with a
completely new install of RH and all the Planet software

   This morning I'm playing CDs just fine as root using:

jackstart -R -d alsa -r 44100 -d Audigy &
alsaplayer -r -o jack &

   Everything works just fine today.

   I have no idea why the previous problems happened, but I'm not sure that
there is a hard and fast killer problem to solve as I'm running just fine.

Mark

I'm really sorry this has been such a pain.

This is normal, jack uses the alsa devices even when no clients are
connected, no other alsa program will be able to use them (unless you
have a soundcard that supports hardware mixing).

Sorry again, hmmm, come to think of it, we never solved the problem of
running with the -R option, right? That is definitely wrong as well and
maybe is pointing at some basic problem that also affects client
connections. Maybe there is a subtle problem with that particular Cyrix
cpu and the options the kernel was compiled with, although that is hard
to imagine (I would assume that nothing would work right, not just
jack). Usually all this "just works"(TM). For some reason I have the
feeling that I'm missing something really obvious.

One thing that just occured to me (although again I don't see how this
could be wrong). Jack uses some files in /tmp, maybe they have the wrong
ownership. Do an "ls -l /tmp/jack*" while jack is running, those files
should be owned by the user that is running jack.
