[PlanetCCRMA] Jack problem

[JJ Kangas]

Hi!

Firstly, sorry my bad english :).

When I start jack (jackstart -R -d alsa -d hw -r 44100) , follows:

jackstart: cannot get realtime capabilities, current capabilities are:
           =ep cap_setpcap-ep
    probably running under a kernel with capabilities disabled,
    a suitable kernel would have printed something like "=eip"

back from read, ret = 1 errno == Success
jackstart: could not give capabilities: Operation not permitted
jackd 0.99.36

JACK compiled with System V SHM support.
loading driver ..
apparent rate = 44100
creating alsa driver ... hw|hw|1024|2|44100|0|0|nomon|swmeter|-|32bit
configuring for 44100Hz, period = 1024 frames, buffer = 2 periods
nperiods = 2 for capture
nperiods = 2 for playback

Is this serious?
I have RME Multiface.  Does anybody know optimized values running jack (or 
is jackstart -R -d alsa -d hw -r 44100 OK?)
In Ardour, I imported one track, and I can listen it (from Multiface Line 
Out), but I can't play any CD's (I hear nothing): do I have to change 
settings (mixer settings, routings etc. ?)  But this is not so important.

Thanks!
