Yes, this works. It's the default setup on our IdPi's.
Did you reboot after doing the setup?
Are you running MC as the user (or group) for which you setup the thread priorities?

Thanks Bob....
User pi is in the audio group:
pi@raspberrypi:~ $ groups
pi adm dialout cdrom sudo audio video plugdev games users input netdev gpio i2c spi
Here is the end of the limits.conf file:
# End of file
@audio - rtprio 100
I followed the instructions verbatim and rebooted several times. I didn't get any errors. My other pc linux install priorities work fine, just not the pi (3). Currently I am getting the following on the pi3:
pi@raspberrypi:~ $ ps -T -eo pid,tid,class,rtprio,ni,pri,comm | grep mediacenter23
1428 1428 TS - 0 19 mediacenter23
1428 1775 TS - 0 19 mediacenter23
1428 1779 TS - 0 19 mediacenter23
1428 1785 TS - 0 19 mediacenter23
1428 25842 TS - 0 19 mediacenter23
pi@raspberrypi:~ $
Any help is appreciated.

Seems fine to me
I am assuming you are running a fairly current build of MC 23?
You might try change the @audio in /etc/security/limits.conf to pi instead (if you are running MC as the pi user).
Maybe look for errors in limits.conf?

Yes, running version .93.
I already tried changing @audio to @pi with the same results.
I don't see any errors in limits.conf, actually all lines are commented out other than what I added.
I will try reverting back to a previous version of MC.
EDIT: Reverted back to stable .80 with same results.
OBSERVATION: It's been a while since I did the initial MC install and can't remember how I achieved MC autostart. It may be related, now when I exit MC in Raspbian MC restarts automatically without reboot, cannot keep MC closed.

I was thinking to try the pi without @ in front of it (pi user not group).
The autostart may be the issue. It could be autostarting before limits.conf is read.
