I have an XBox 360 and some wired Turtle-Beach style headphones (they are actually Plantronics, but the connections are the same as the TB X11, X12 etc).
I wanted to connect to the TV via HDMI and still have the audio output from the XBox piped through the headphones (as opposed to the TV speakers).
First off, I tried getting a normal (composite) XBox video lead, cutting off the tab that stops you inserting the HDMI lead at the same time, plugging that in as well, and then connectiong the audio jacks to the headset. No worky. I get a message on screen saying "Unsupported Signal. Adjust your PC output".
Second, I tried piping the audio output from my TV to the headset, but this is linked to the TV volume so although I get sound in the headset earpieces, I still have sound out of the TV (which is what I want to avoid).
So, short of abandoning hope of getting a hi-def video signal via HDMI, is there any other route I should be trying?
I know I could switch to a component lead and use that instead for HD gaming, but I'm trying to avoid shelling out any more than I have to.
