I can't even find a man page for devfs. There's a file /etc/devfs which just has two directories in it: conf.d and devices.d. conf.d has one file: nvidia-kernel-ufc which doesn't look useful, and devices.d is empty. > Otherwise you may just need to: > apt-get install alsa alsa-base > (and various other alsa* packages.) I did this earlier to clean out anything left by my attaching the USB card. (I have a nasty feeling that the mail that I mentioned this in is awaiting the attention of the mods, as I attached the asound.state file which is a bit big.) Can't see much point in doing it again! Unless you can. > Or run the snddevices script. > find / -iname '*snddevice*' Not on my machine. This of course may be the problem. > HTH As you can see, a bit.
