Then this must be OK. Then the remaining possible problems are:
- Device files and permissions. Check whether /dev/snd/* files exist and have proper permissions and ACL (see "getfacl /dev/snd/*")
- The default ALSA configuration is hijacked, e.g. via pulse plugin. Try to remove /etc/asound-pulse.conf if present.
