792Another reason for error messages similar to the ones above could be a file in
793<path>/etc/modules.d</path> supplying a <c>device_mode</c> parameter when it
794isn't required. Confirm that this is indeed the issue and find out which file
795is the culprit.

807Usually it is a file called <path>alsa</path> with the line <c>options snd
808device_mode=0666</c>. Remove this line and restart the alsasound service and
809that should take care of this issue.
