Eperiment with audio
Since all the forums I have read regarding this topic have not been able to truly answer the question i did the following experiment.
First my equipment:
1. 40" LCD-LED Sharp Aquous 700UN, labeled Dolby Digital, and digital output.
2. Bluyray Sharp HPU16
3 DVD/Home theater combo (1080p Upscale) dolby digital II.
Note: No matter what surround signal the receiver gets it always turns on the surround light and displays "Prologic II Movie
The experiment:
Since there is a lot of uncertainty whether the TV can pass the 5.1 (bitstream) signal to the receiver I decide to do the following:
1. Plugged the BR to directly to the Reviver through digital output, and play the BD with dolby 5.1
Result: Great sound effect.
2. Unplugged the the digital cable and passed the sound through the RCA cables using the aux in the receiver. Obviously 2.0 Channels.
Result: Still able to get surround effect, but it sounds to low, so some effects can barely being heard. However, i was able to tell the difference because I just had listened the same scene on digital output.
3. Knowing the difference, I passed the BR audio signal along with video through HDMI to the TV, and then from the TV to the receiver.
Result: If there is difference between test 1 and 3 I cannot distinguish it, so either my ears and brain don care, or the sound is 95-100% the same.
4. I changed from BR to TV (which I know for sure decodes dolby digital), and watched HBO that transmits with 5.1, sending the sound through the digital cable.
Result: I could not tell the difference, it sound same as test 3
5. I unplugged the digital cable from the TV, and sent the audio through RC cables using aux in the receiver.
Result: Same as test 2, Still able to get sorround effect, but it sounds to low, so some effects can barely being heard.
So, after all the testing I left my system plugged the following way:
From BR to TV using HDMI, then from TV to receiver using digital cable.
does the TV can handle 5.1?? I don't really know. All I know is I cannot tell the difference between sending 5.1 direct form BR to receiver, and sending signal first to TV using HDMI and then to the receiver using digital cable.
So leaving my system that way, i can watch the TV with 5.1 signal and watch my BR movies without plugging the digital cable from one device to the other.
I'm not saying that all the other arguments are not correct, I just did the experiments, and here I give you the results. You be the judges of what is going on, and if anybody know why I can tell the difference (if there is any) let me know, it would be nice to know. (
