# Use libertine numbers in math mode and with siunitx

I am here again to seek your help. I would like all numbers in my document to be the same (in text or math mode). Now I have

Please note also the size difference. What is the way to have all numbers in Libertine irrespective of their environment? I mean leaving siunitx behaviour as it is and changing only the font for numbers (and for numbers alone) in math mode?

If I try

\DeclareSymbolFont{numbers}{T1}{LinuxLibertineO}{m}{n}
\SetSymbolFont{numbers}{bold}{T1}{LinuxLibertineO}{bx}{n}
\DeclareMathSymbol{0}\mathalpha{numbers}{"30}
\DeclareMathSymbol{1}\mathalpha{numbers}{"31}
\DeclareMathSymbol{2}\mathalpha{numbers}{"32}
\DeclareMathSymbol{3}\mathalpha{numbers}{"33}
\DeclareMathSymbol{4}\mathalpha{numbers}{"34}
\DeclareMathSymbol{5}\mathalpha{numbers}{"35}
\DeclareMathSymbol{6}\mathalpha{numbers}{"36}
\DeclareMathSymbol{7}\mathalpha{numbers}{"37}
\DeclareMathSymbol{8}\mathalpha{numbers}{"38}
\DeclareMathSymbol{9}\mathalpha{numbers}{"39}


LuaLaTex complains there are no such shapes.

Here is the minimal example

% !Mode:: "TeX:UTF-8"

\documentclass[a4paper,11pt]{book}

\usepackage{fontspec}
\usepackage{unicode-math}
\setmainfont{Linux Libertine O}
\setsansfont{Linux Biolinum O}
\setmonofont{Consolas}
\setmathfont[math-style=ISO,bold-style=ISO]{Cambria Math}
\usepackage{siunitx}

\begin{document}
Now I have
\begin{itemize}
\item Libertine in text mode: 123456789
\item Libertine using siunitx in text mode: \SI{123456789}{\km\per\hour}
\item Cambria in math mode: $123456789$
\item Libertine using siunitx in math mode: $\SI{123456789}{\km\per\hour}$
\end{itemize}
I would like libertine in math mode too $123456789$.
\end{document}
