Frans, please have a look at the initscript:

restore_levels()
{
    [ -f /var/lib/alsa/asound.state ] || return 1
    CARD="$1"
    [ "$1" = all ] && CARD=""
    # Assume that if alsactl prints a message on stderr
    # then it failed somehow.  This works around the fact
    # that alsactl doesn't return nonzero status when it
    # can't restore settings for the card
    if MSG="$(alsactl restore $CARD 2>&1 >/dev/null)" && [ ! "$MSG" ] ; then
        return 0
    else
        # Retry with the "force" option.  This restores more levels
        # but it results in much longer error messages.
        alsactl -F restore $CARD >/dev/null 2>&1
        log_action_cont_msg "warning: 'alsactl restore${CARD:+ $CARD}' failed with error message '$MSG'"
        return 1
    fi
}

Thanks for your engagement. Anyway, I'll close the bug now.
