Hi Kron
It is not optimal to use Airport Express in a system without audioproduct. However, it is possible.
Simply connect a Phono, on a phono to minijack cable to one of the AV connections, and the other end to the airportexpress.
This works, however, your screen is on and you have to press picture mute for it to turn off.
