I have opened konqueror in super user mode and done a search starting from / and the only matching file I can find is in file:///usr/share/doc/kernel-doc-2.6.18/Documentation/video4linux/bttv/Modules.conf. I do have a modeprob.conf in /ect and it does have some sound entries in it. I can post the contents if needed. -- Guy Fawkes, the only man to enter the house's of Parliament with honest intentions, (he was going to blow them up!) Registered Linux user number 414240
