In the Playstation 3's Settings area there is something that looks vaguely like a Wii's remote... under that there are peripherals i believe, you have to set the microphone to respond to your usb port that way, as well as once this is set up you can make it so that voices come over the headset instead of the TV. If you know how to set the microphone sensitivity it should be directly beneath that.

I don't recall what it says off the top of my head, but there should just be 2 options generally speaking one turns the microphone on, the other off.

thanks for your reply,

Directly under the mics sensitivity there's input and output- For input i have the USB sound card, for output i have system default. so the MIC goes IN and the Voice (from other people) comes out my speakers, Which i want. It works on the Playstation but not in game( or people say they don't hear me )

I have it set correctly, Just doesn't work in Dust. .. yet.

edit: i wonder if there's something in my PS settings blocking the use of voice in Dust, like a control put in there so i can't talk to people. : ( I'll keep looking.

Have you tried turning off PTT? I was unable to get voice to work with PTT on. It shows a disabled Mic in channel on my name with it turned on.

I think this has been fixed. I have a similar setup with a USB preamp connected to a professional microphone. I had problems until the battery in my bluetooth headphones died (was using them to listen to voice channel). Routing from my preamp to the channel and from the channel to my speakers I was finally able to get a response from someone. I too prefer PTT to VOX. I don't want to hear your dog/radio/wife in the middle of a battle .
