Hi everyone, I just bought an HD6450 and installed the latest drivers (12.4 ccc) and I am having an issue where anytime the audio changes or I change programs, etc there's a 1-2 second delay where the receiver tries to figure out what it's getting and then I hear audio. It's really annoying.

Also, what are the recommended settings for an HTPC in CCC? Thanks!

The delay is quite common because the receiver needs time to determine the input signal and act accordingly.

Fairly normal across all manufacturers. If you really despise it get the hdmi detective.

it actually seems to be closer to 3-4 seconds. I thought I read it was fixed with ATI cards? Also, why didn't the delay seem to happen when I was hooked up to the motherboard coaxial?

3-4 seconds is still normal. When audio and video is passed through HDMI, HDCP handshake delay is normal, whereas coaxial/optical signal is not subject to HDCP hence the delay with HDMI.

+1. Yep, its the handshake.

Again, consider investing in the HDMI detective if this really bothers you as it might reduce or even eliminate these few seconds of waiting.

Dang it...it is a bit disorienting turning on Media Center and seeing people in a TV show or movie moving their lips while waiting for my receiver. Oh well.

What are your thoughts on ITC processing and/or GPU scaling settings for the card? Should I enable those? Should I do 0-255 for color or the 16- whatever if this is almost exclusively for Blu-ray and TV/Media Center?
