Yes, it would be good if you would open a bug report about this. No it
wouldn't be good if you'd post it like that.

Identify which control exactly was incorrectly initialized. Identify a
good value for it. And then describe exactly which card you have, and
file a bug against alsa-utils. 

Even better, have a working patch ready for alsa-utils. Most folks
will probably have to add a few lines to /lib/alsa/init/hda and that's
about it. The syntax is similar to udev rules. Just read that file and
you should be able to deduce the format it is written in. Then use
'alsactl init' to test your changes.
