So I've tried lots of variations on startup, uids, setuid or not etc. I just
found that the "JACK_START" control in /etc/rc.d/init.d/rivendell or
/etc/sysconfig/rivendell was no (guess I changed it back to no sometime
yesterday), so I set it to yes. However, these are slower PCs, and so the
sequence
jackd … &
ipcrm …
caed …
was not executing in order, and jackd had not started successfully before caed
had grabbed the alsa device and so jackd wasn't starting that way. I added a
sleep after the jackd … & to make sure it got the device.
So right now, I see them all running under the same id.
[radio@localhost ~]$ ps lxa | head -1;ps lxa | egrep '(caed|jack)' | grep -v
grep
F UID PID PPID PRI NI VSZ RSS WCHAN STAT TTY TIME COMMAND
0 500 9037 1 20 0 94844 32152 - SLsl ? 0:02
/usr/local/bin/jackd -d alsa -d hw:0 -r 48000
1 500 9044 1 20 0 60808 7120 - Ss ? 0:01
/usr/local/bin/caed
0 500 9086 1 20 0 149236 30988 - SLl ? 0:03
/usr/local/bin/qjackctl
I'd like to check jack by itself, but I don't know how to do that since all the
desktop testing etc wants to use pulseaudio services. Since I've been many
servers and maintain them daily, the mechanics of all of this are familiar.
But, I don't know anything about the linux audio tools state these days. Where
does the vlc-jack.plugin fit in at? Some specifics would be most helpful.
Regarding RDAdmin…Audio Resources, it is now showing no audio devices, where as
in the past, I have seen the Jack "card" visible there with an 8x8
configuration. I remove setuid root on everything to try it that way, and
perhaps there are permissions which are now not allowing access.
