Madcatz HD/VGA

[Banny]

Just got one of these for the X-Box, have plugged into TV, but get no sound coming out of TV.
Tried it on my PC it worked fine through my X-Fi breakout unit.
have tried all setting on the xbox to no avail.
Have plugged the audio cable from cable into the tv audio in and still nothing am I missing something.
Thanks for any help.

I have just sussed out that the audio inputs are on AV3 on my TV but the VGA input is RGB on my source select, does that mean I am buggered then or is there a way round it.
