Sorry but I forgot to paste the limits file in the last email.

One caveat is that for realtime schedulling access as a normal non-root
user
you will need to either install the Planet CCRMA version of "pam" (part
of planetcore, pam-0.79-9.6.2.rhfc4.ccrma), 

How do |I do this Fernando?

or


"edit /etc/security/limits.conf to give everyone (or a group) access to
realtime priority. The relevant part of Planet CCRMA's configuration is:

*               -       rtprio          99
*               -       nice            -10
*               -       memlock         4000000"

Here is my limits.conf file but what are the changes that I need to make
to enable an ordinary user to have root privelages so that the audio
apps can be run in real time?
#*               soft    core            0
#*               hard    rss             10000
#@student        hard    nproc           20
#@faculty        soft    nproc           20
#@faculty        hard    nproc           50
#ftp             hard    nproc           0
#@student        -       maxlogins       4

# End of file

Will get back to you on this one but it all was bought around Nov 2004
and was very new then.

Yes, that should be possible. I have not tried it but it should work.
Just don't add the "planetcore" repository to the apt configuration. One
caveat is that for realtime schedulling access as a normal non-root user
you will need to either install the Planet CCRMA version of "pam" (part
of planetcore, pam-0.79-9.6.2.rhfc4.ccrma), or
edit /etc/security/limits.conf to give everyone (or a group) access to
realtime priority. The relevant part of Planet CCRMA's configuration is:

*               -       rtprio          99
*               -       nice            -10
*               -       memlock         4000000

What hardware do you have? It may be too new for proper support by the
linux kernel and that's why you are getting so much grief from it.
