Is devfs required? What is > the best way of handling these sound devices? No you don't need neither devfs nor using MAKEDEV when using udev. It will create devices for you, when modules are properly installed and devices working fine. Please, check you have something like this in /dev/snd/ jose@gimli:~$ ls /dev/snd/ controlC0 pcmC0D0c pcmC0D1c pcmC0D3c pcmC1D0c timer controlC1 pcmC0D0p pcmC0D2c pcmC0D4p pcmC1D0p Those are devices being used by ALSA. /dev/dsp* are the OSS layer emulation, which seems that you should have been loaded, as you have snd_pcm_oss and pcm_mixer_oss. Also, check if you are suffering the problem described in my blog: http://www.tribulaciones.org/blog/computers/debian/discover-hotplug_28-11-2004.html Hope it helps, -- Jose Carlos Garcia Sogo jsogo@debian.org
