Description Paul Smith 2006-08-31 19:07:18 UTC

If I try to copy an audio CD, as a normal user, with the command 

cdrdao copy --eject --device /dev/dvd

I get the following warning:

«WARNING: No super user permission to setup real time scheduling».

The warning persists even after 

chmod u+s /usr/bin/cdrdao

but no progress.

No warning is given if I copy the audio CD as root.

  Can you successfully copy the CD anyway?  In bug #191684 is the problem that
cdrdao doesn't work for writing as a normal user at all (maybe this is only for
data CDs?).  It's normal to get warnings from cdrecord when running as a normal
user:

cdrecord: Cannot allocate memory. WARNING: Cannot do mlockall(2).
cdrecord: WARNING: This causes a high risk for buffer underruns.
cdrecord: Operation not permitted. WARNING: Cannot set RR-scheduler
cdrecord: Permission denied. WARNING: Cannot set priority using setpriority().
cdrecord: WARNING: This causes a high risk for buffer underruns.

I'm guessing that your warning is normal as well.
