Xine and root privileges

I've tried running Xine without root privileges and it can't play VCD, etc. I do not yet have traced the source of the problem. I'm running Debian SID (unstable). Using root privileges it works fine ... without it doesnt.

Any help is greatly appreciated.

My user is markus and is a member of the audio group (playing music works just fine).

HOWTO solve the problem

Okay after taking out my favourite tool (lsof) I found out that it was a permission problem in /dev as you can see.

First of all start x11 as root and open up xine and play a movie. Now enter the console and execute the following:

ps auxw | grep xine | awk '{print $2}' | while read pid; do lsof -p $pid; done | awk '{print $8}' | grep ^/dev | sort | uniq

Which will return (in my case; /dev/hdc = cd-r drive)


and the default permissions:

crw-rw----    1 root     audio     14,   3 Mar 14  2002 /dev/dsp
brw-rw----    1 root     disk      22,   0 Mar 14  2002 /dev/hdc
crw-------    1 markus   tty        4,   1 Aug 18 22:13 /dev/tty1
As you can see you either require to modify something in /dev - which I would not recommend except for some group change or you need to add the user allowed to plax xine stuff to those groups.
