Because devfs isn't enabled.

Your kernel configuration isn't wrong. If you don't know what devfs
is, don't enable it.

It wouldn't. The files in /proc/asound are just for debugging and/or
tuning.
The files in /dev are used to actually access the sound devices (OSS
emulation devices like /dev/dsp, and ALSA devices in /dev/snd/). If
devfs is not enabled, you can change the permissions of the files in
/dev with chmod.
