Dear developers,

I'm sorry if I write to the wrong list but I just catched several log =

messages that I was advised to report as a bug to you, the ALSA developers.

I'm not experiencing any sound problems by ear, just found these =

messages in the syslog (via logcheck).

Ran the alsa-info_alsa-info.sh shell script and its output can be found =

here:

http://www.alsa-project.org/db/?f=3Dd9b579a048b94cdc71e619c4deac60e4c8228dbb

The log messages in question read as follows:
