Fascinating. As I'm not looking at a monitor, my report is based on what
I hear from my talking interface. It definitely says "failed failed
failed." However, while going to clipboard that into this email for you,
I saw no such thing. So, here's from /var/log/messages. It seems the
explicit modprobe load might actually it, not sure about the script, the
result in messages is different:

Dec 29 14:05:27 concerto rtload: rtload: rmmod is not installed failed
Dec 29 14:05:27 concerto kernel: Realtime Capability LSM exiting
Dec 29 14:05:27 concerto rtload:  succeeded
Dec 29 14:06:06 concerto rtload: rtload: modprobe is not installed
failed
Dec 29 14:06:06 concerto rtload: rtload: modinfo is not installed failed
Dec 29 14:06:06 concerto rtload: rtload: lsmod is not installed failed
Dec 29 14:06:06 concerto rtload: rtload: rmmod is not installed failed
Dec 29 14:06:06 concerto kernel: selinux_register_security:  Registering
secondary module realtime
Dec 29 14:06:06 concerto rtload:  succeeded
Dec 29 14:06:06 concerto kernel: Realtime LSM initialized (all groups,
mlock=1)
So, I'm not sure what the failures are, but lsmod definitely lists the
module:

#lsmod |grep realtime
realtime                5128  0
commoncap               8192  1 realtime
[root@concerto 14:20:58] ~#

jackstart still complaines realtime capibilities are missing, though.
And, doing:

#service rtload status
Realtime kernel module is loaded, current parameters are:  [FAILED]
 any=1; gid=-1; mlock=1

>From time to time, I get the following in the console:

My next steps are hdsploader, hdspconf, and hdspmixer, after which I get
sound--even though the last two can't open the GUI sessions they want.

HTH.

Thanks, Fernando.

If Linux doesn't solve your computing problem, you need a different problem.
