R600XT has an audio part and we already talked about it. But only when you get inside the driver do you get the real story.
The Radeon HD 2900XT and the soon to come 2600 and 2400 cards will have an audio rear output, line out, rear line input, rear mic, audio front headphone, front mic, digital in and out and aux digital and so on. Sounds like a real sound device to us, but this is the short list what the Radeon HD can do for your sound.
