And it isa fact. As you just said, The udev configuration files do not specify anymodule options. I just checked my alsa configuration files to see if it was no miss-spelling init, ran a modules-update, removed snd-usb-audio from my blacklist file, done areboot, and the result was my webcam as sound card 0 when it is sound card 1 inmodules.conf. The situation is different if I do a "/etc/init.d/alsasound restart", becausehere, alsasound will first unload any sound module and reload them again. Afterthis, I will get the same order as in modules.conf: 0: audigy, 1: usb, 2:virmidi This problem have at least tree aspects.1) The alsa documentation use modules.conf and not udev,2) the init process run udev and hotplug before to load the modules inmodules.conf,3) the average users just want at the sound work out of the box, and 3b) theyare not confident with udev rules. A simple fix will be at "alsasound start" that most if not all the linuxdistribution are using to load the sound modules at boot time, first check forexisting drivers and unload them if any before loading them. So, the sound cardsorder will be correct in any cases. Dominique -------------------------------------------------------------------------Take Surveys. Earn Cash.
