first of all you should get your self into linux basics

1.) smb.conf is in no way related to sound that is the config file for samba

2.) to test existens of an file
ls -al /dev/snd
would be the way to go

3.)
try
/etc/init.d/alsa start
and see if the /dev/snd comes up

What version of udev are you useing. I and others have had the issue where udev does not create /dev/dsp or /dev/sound. The ones I know of are udev-.079 and udev-.078. I downgraded to udev-0.70 and all is working. I also experienced the is of no sdb1 or sdc1 when my usb drive were plugged in and dmesg said they were at sdb1 and sdc1. If the usb drives are not an issue try typing udevstart ast root.
