audio:x:29:jordeam Is that ok? Or the correct group is audio_user? I believe the line above, in /etc/group, was generated by users-admin.

Also, if I install all the system, the alsa will work fine, but if I run alsaconf, this error will happen again. I did it once :) but I do not want to reinstall all system again. I would prefer to find a "scientific" explanation for this behavior :) BTW I am using lenny, with alsa 1.0.14. Regards -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
