Xbox 360 - divert Xbox Live audio to headset

[Taz]

I've now got my Xbox 360 and have set it all up. However, when I go onto Xbox Live the audio comes out of my TV instead of the headset connected to the wireless controller. I cannot find the setting to divert Xbox Live audio to my headset. Could someone point me in the right direction please?

By the way, I still want the game music/sounds to come from the TV, I just want the audio on Xbox Live to come from the headset.

What game in particular? The only game I've played on Live (PGR3) does that automatically as soon as I plug the headset in.

Rys, I've just found out where to do it. Yes, it's with PGR3 but it didn't do it automatically for some reason. It's in the confugration setup for PGR3 itself. Anyway, it's all sorted now. I've just migrated my Xbox Live account and am awaiting the next Hexus Xbox Live PGR3 fest!

I am rubbish at the game though!
