>Release: FreeBSD 5.0-CURRENT i386
>Organization:
Meyer Consulting
>Environment:
A system with at least one sound card.
>Description:
The system mixer settings - possibly carefully tuned by the user -
are lost whenever the system goes through a hard shutdown.
>How-To-Repeat:
Reboot your system so that the mixer settings are at the default
values. Find a line input source that's not acceptable at those
values, and adjust the mixer settings. Now reboot again, and notice
that the values you had saved were gone.
>Fix:
The following patch (apply in /etc) adds an rc.conf knob to save the
mixer settings in /var/db on shutdown, and restore from those files on
restart.
And I forgot to test the "mixer numbers" case, but shutting down now
to do it would lose the PR entry, so...
