Dear Mike Meyer,
Under -STABLE, I had solved this "problem" at a user level as follows:
<blockquote>
#
# $FreeBSD: src/share/skel/dot.login,v 1.11.2.2 1999/12/13 05:47:28
# dcs Exp $
#
# .login - csh login script, read by login shell,
# after `.cshrc' at login.
#
# see also csh(1), environ(7).
#
<other user settings snipped>
# Cdcontrol-related stuff
setenv MUSIC_CD /dev/acd0c
mixer dev vol 100 100 > /dev/null
mixer dev igain 75 75 > /dev/null
mixer dev ogain 75 75 > /dev/null
mixer dev pcm 33 33 > /dev/null
mixer dev cd 100 100 > /dev/null
mixer dev mic 0 0 > /dev/null
mixer dev speaker 0 0 > /dev/null
mixer dev line 0 0 > /dev/null
mixer dev bass 90 90 > /dev/null
mixer dev treble 90 90 > /dev/null
mixer dev synth 90 90 > /dev/null
# I determined the above settings by trial and error.
# Your mileage may vary.
</blockquote>
Whether I use cdcontrol (when working in CUI/CLI), or KDE cdplayer
(when working in GUI), the settings are preserved.
There is more than one way to do it(tm) :-)
Best regards,
Salvo
