Default Sharp Aquos/Optical Surround Sound Problem

I have a Sharp Aquos LC42D62U and a Samsung home theatre surround sound system (5.1.) My friends and I attempted to hook the surround sound up last night, but we ran into a problem where the two HDMI inputs (where I have my XBOX 360 and PS3 connected,) will not work through optical. Only my HD satellite receiver will work through optical. I didn't check my Wii, which is in the second component input. We got it to work with some red and yellow lossless audio cables and it sounds good, but I assume optical would sound a bit better.

Is there a reason why my TV won't reroute the audio to the two HDMI inputs? I'd like to use the optical cable that came with the surround sound system. My friend told me he thinks it sounds better in my room than his optical surround sound does in his room, but I'd still prefer to use optical. The fact that it won't work with optical makes me feel like the TV is gimped (excuse the term) and angers me. I wouldn't have purchased the TV if I had known it wouldn't allow the optical surround to work with its two HDMI outlets and will never buy a TV from Sharp again.

It's normal for tv's to not sent 5.1 signals out via the optical when the input is HDMI. Only stereo is output. You should be connecting your devices (such as the ps3 and xbox) directly to your receiver.

For example, video goes from my ps3 to the tv via HDMI, and audio goes from the ps3 to my 5.1 surround system via optical.

I know the tv's will output 5.1 when the source is the coax cable, or perhaps componant, but not HDMI or other digital souce.

Thanks for the reply.

Is there a lot required to do that? I'm somewhat of a noob when it comes to setting this stuff up, so forgive the stupid question. It's good to hear it's possible though.

Depends on your receiver. Sounds like you have a lot of stuff. I have an older Home theater in a box, which only has two digital audio inputs, an optical and a coax, so I can only easily hook up two surround sound devices. Beyond two, I'd be looking at optical switches and stuff. I really need a receiver had process hdmi audio and video...

SO, what kind of connections do you have on your receiver?

Here's a link to a description of the system and all of the details about its speakers/ports:

My friend said he tried to do that, but: the audio is going through the reciever, and the video is going through the HDMI ports, but the HDMI ports wont redirect the sound to digital out.

Well, it seems there is only 1 optical jack back there. Which means you can only get surround sound from one device. So you can get a switch like this one:

That will let you hook 3 devices with optical audio to the one jack on your receiver. You would just need to turn the switch each time you want to hear something different.

It should. It is just a set-up issue. For the ps3, in video settings (in the ps3 menu system), you choose hdmi for video out, and is audio setting, you choose optical out. I'm sure the xbox will allow you to also choose hdmi for video, optical for audio. Same with the HD satellite receiver.

I hope that will work. He seems to think it won't because it's something Sharp implemented where they chose HDMI over optical or something. The TV has simulated surround but the surround I'm using now sounds better and I'm sure the optical would make it sound a bit better as well.

He's also under the impression that there will be quality loss because of the three optical cables being put into the switcher, but I assume there won't be because it's not a splitter and only one thing is in use at a time.

I personally don't have that switcher, but others here do, and they say it's great. I remember reading one post of someone who couldn't get it to work, but that person also had like a 60 foot optical cable or something. There should be no degrading of quality with the switch. It will either work, or it won't.

Before I spend money on this method, how much better is surround sound when it's connected via optical? The surround sound I have right now sounds pretty good.

Hello, this is the guy who hooked everything up. I have it running through standard audio cable from the audio out to the receiver through reinforced low loss cable. I noticed a post on the future shop forum about the owner’s manual stating that you cannot set sound to go from the outputs 4 and 5 (the only two HDMI on the TV) to run through Optical. But the switch you mentioned seems to be a great alternative. Personally I have a Samsung 40" 1080p with a Samsung 480p HDMI out theatre in a box system. I have everything (Xbox 360, Nintendo Wii, DVD player, Bell expressVU) all hooked up through a single optical out through my TV and into my receiver. Everything works fine, without any trouble. This is the second sharp I've run into this with and the standard audio cable fix seems to be a perfect way to get around it without spending much money (buying the switch, more cables) anyway, just thought I'd come on here and give my two cents.

Optical will give you true, 5.1 channels of sound. the simulated surround the tv does through it's tiny stereo speakers is funky audio delay stuff that gives you the impression that audio is filling the room. But it won't make you turn around to see what the sound is that was behind you. Stereo cables (the red and white) going into your receiver can do 1 better, pro logic. That will give you 4 channels of sound. That would be the left, center, right, and a mono surround sound. The subwoofer gets no dedicated channel either.

I think you will see a big improvement using 5.1. Especially in PS3 or XBox games such as Dead Space. That game keeps making me look behind me as to the source of dropping wrench sounds.

Well, if all those things are feeding their audio into the Samsung tv, and then the optical out to the receiver, all you are getting is stereo sound. If it sounds great, and you enjoy it, then my all means stick with it. But it isn't 5.1, nor surround sound. You are getting crystal clear 2 channel sound.

I decided to go out and buy a new receiver. I found a Sony 7.1 receiver on-sale at Future Shop, for $250 (regularly $325,) so I bought that. It was the last unit that any of the local stores had in-stock. It has 3 HDMI inputs and 2 component, so it should work flawlessly.

I hope to get it set-up this weekend.
