I'm trying to stream a HD movie on a LG LHB976 Blue-ray Home Theatre combo unit using the Amazon app that's on it. The picture streams as HD, but I'm getting audio in stereo instead of 5.1. The unit is connected via Cat 5e directly to my router. A speed test on my connection shows I'm running at 22 Mbps. I get 5.1 on other inputs into the box. I have the latest firmware for the box. I can't find any option under settings to change the audio.
I contacted Amazon and they verified that the movie I purchased should have 5.1 audio. They also stated my connection was fast enough to support HD and 5.1 streaming. They did not have anything that shows any kind of limitations for that particular box.
I contacted LG and they were pretty much useless. They suggested changing the "Sound Effects" to "NATURAL PLUS", but all that does is have the same audio that's coming out of the front speakers, come out the rear speakers.
Does anyone have any ideas how to fix this problem? Has anyone else seen this problem? Could it be a limitation of the LAN port on the unit? Could the box be defective?
Thanks for any help!
