Whoa, that's exactly what I am doing : logging in as 'root' and after that 
logging in as 'user' in a different X session !
Are your tips still valid then ?
This requires some studying for me, since I'm relatively new in the Linux 
environment. 
In the meantime I have - temporarily - circumvented the problem by writing a 
small script containing both commands :
   chmod a+r /dev/cdrom
   chmod a=+rw /dev/mixer
Now I run this script as 'root' first thing after booting and then all is fine 
(of course).

Would there be any other approach in this multi X-session situation ?
