Thanks for your advices.
I have encountered problems with kernel 2.8.6 and xmms which worked fine as
root but not as user. I posted a question about this to the list xmms-dev and
their reply was: change the permission of /dev/hdc.
The permission origine of /dev/hdc was 660, I put it to 644 and now xmms
works fine for the users. It's a problem with gtk whilst cdcd have no problem.
It works fine for the users with 660 for /dev/hdc. (and 4755 for cdcd)
I tried to put 4755 to xmms but I received a protest of gtk.
( reason of security: http://www.gtk.org/setuid.html )
Now I have upgraded with kernel 2.9.1 and the problem of permission with xmms
I wonder if I am messing my system in changing the permissions of /dev/hdc ?
