My sincere apologies. The thread had evolved a bit further on the
multimedia list. That is where I stated I initialy did not use the
mixer script.
As to the initial problem: forgive me being extremely stubborn. In my
ignorance I though not having any references to the mixer script in my
rc.conf meant I was not using it. I looked over a line in the defaults
though...
Setting the suggested 'mixer_enable="NO"' in /etc/rc.conf *does* make
the hints work.
Thanks to everybody,
