Hi -I have a pair of wireless headphones connected to my TV by the audio out red and white sockets.

They work fine watching the TV via my set top box via scart connection and they work fine with my wii via component cable connection.

I have just bought a media player which is connected by HDMI and there is no sound coming through the headphones with it.This is also true of my DVD player connected by HDMI also.

As you probably realise im a complete noob and any help would be much appreciated.
