Thanks Nate. I checked.

I do have this:
    2 root      -2   0     0    0    0 S  0.0  0.0   0:00.00 softirq-high/0
    3 root      RT   0     0    0    0 S  0.0  0.0   0:00.00 softirq-timer/0
    4 root      -2   0     0    0    0 S  0.0  0.0   0:01.27 softirq-net-tx/
    5 root      -2   0     0    0    0 S  0.0  0.0   0:13.87 softirq-net-rx/
    6 root      -2   0     0    0    0 S  0.0  0.0   0:00.00 softirq-block/0
    7 root      -2   0     0    0    0 S  0.0  0.0   0:00.02 softirq-tasklet
    8 root      -2   0     0    0    0 S  0.0  0.0   0:00.00 softirq-hrtreal
    9 root      -2   0     0    0    0 S  0.0  0.0   0:06.21 softirq-hrtmono

I have not had the problems with ccrma FC3 that I have now with FC5 (as
far as stuttering audio).

I looked in limits.conf and found this as default:
# or (default) allow everyone access
*        -    rtprio        99
*        -    nice        -10
*        -    memlock        4000000

Does this not let everyone have rt access? Why would everyone have rt
access?
