chat adaptor

Have you updated the software on the controller with the chat adapter plugged in?

The adaptor is for the chat cable portion of any headset wired or not. My TB X31's connect via USB to the console. That is the RF signal box part which will be for game sound. The adaptor then converts the chat cable to the new controller port for chat only.

So, I also had this issue with a separate pair of Tritton headphones (AX360s) and thought the issue was a faulty adaptor. Well, I exchanged for a replacement adaptor today and still had the same issue.

My setup was that I needed all audio, including chat audio, to be output via the SP/DIF but with the MIC in going through the headset adaptor. Chat audio would cut out from the SP/DIF as soon as I plugged my MIC in but people could hear me once I did that.
So I reckon this is a software issue where the adaptor incorrectly thinks I've plugged in a headset that should get chat audio from the headset adaptor direct (i.e. like the official xbox stereo headset).

Took both adaptors back in the end for a refund.

After doing a bit of research it sounds like you have it set up correctly, but there seems to be a bit of negative on the way the adaptor works with the x12's.

Firstly if you want to use the same set up as... usb to your X1 and and the chat cable to adaptor then make sure your chat dial is all the way up on your x12's, then you will have to balance the game/chat audio with the game/chat buttons and the volume buttons.

The volume on the adaptor works like a slider, you can raise your chat by pressing chat button then + volume button but doing so will turn the game volume down and vice versa.

The other way to connect is to use your tv audio for game sound then turn the game volume down on the adaptor and the chat all the way up, then just use your chat wheel on the x12's to control chat volume.

Hope I made sense?

adaptor is being made for sound but voice chat might not be available
