Description ykerb 2005-10-09 09:20:15 UTC

Version:           2.2rc1 (using KDE 3.3.2, Mandrake Linux Cooker i586 - Cooker)
Compiler:          gcc version 3.4.3 (Mandrakelinux 10.2 3.4.3-7mdk)
OS:                Linux (i686) release 2.6.11-6mdk

The first KDE session has sound via KMix. The files in /dev/snd are owned by the firt user connected. The others KDE session have not sound because "Mixer not found". 
The files in /dev/snd are still owned by the first user.

The permissions of the /dev/snd files are set by your operating system - this is normally done when a user logs in to a X session. The reason why your OS vendor has chosen to do so, is very likely security issues: For example if you have a microphone attached, another user could open the "microphone stream" and listen to you.
I can only give you hints how to solve your problem. If it doesn't help, you have to ask your OS vendor or internet forums.
Hints: Looking in the /etc/X11/xdm/ directory is a good start. My SuSE9.3 works different (uses an audio group), but there are other permission changes on Login handled: For example there is /etc/X11/xdm/GiveDevices , which handles the permission change of /dev/xconsole and /dev/tty0.

KMix cannot override your system security, thus I'll close the bug report.
