Another part to my hdmi question?

Question:

Whats got me confused is Im using hdmi from my hd directv receiver to my tv.My directv is set to 5.1 audio. I dont use my tv speakers much but i noticed with this hdmi cable if i am using my tv speakers if its a channel thats using 5.1 a sizzling sound is coming out of my tv speakers unless I turn the 5.1 off in my directv receiver thens its fine.why is that.?

Answer:
The earliest version of HDMI did not support Dolby 5.1. If you have an older receiver, that may be the problem. The sizzling sound is unusual, though; you would get no sound at all (if an early HDMI version were the reason). This sounds more like a problem with your TV: are you sure your TV can decode Dolby 5.1? Does it have outputs for surround and center channel speakers? Just because a TV accepts HDMI does not mean it can decode Dolby 5.1. Check the specs on your TV.

HDMI sends audio and video. It sounds like your TV is having difficulty decoding the 5.1 audio coming from your DirectTV receiver. If you have audio going from your DirectTV to your surround sound receiver, then I suggest disabling your TV speakers.

It is the recommended configuration to have HDMI to carry video to your TV, then always have the surround sound audio from your video source directly to your AV receiver. Right now, trying to use HDMI to carry audio and video is just a mess for everybody because this will only make sense when people have an AV receiver with HDMI input/outputs.
