ati hdmi audio question

[QuantumPion]

I just started using the HDMI audio output on my 5870 instead of using an optical out from my X-fi HD, because the audio lag caused by the DTS-Live was starting to annoy me. I just have a quick question - do I have to install a separate driver or any software from realtek?

I just have the standard 11.2 catalyst drivers installed, with an HDMI cable going from the card to my receiver (and DVI from the card to my monitor) and everything seems to be working fine so far (although I am missing CMSS).

AMD has been packaging the HDMI audio driver in their Cat releases for a while now, so no, you don't need anything from Realtek.
