+Mystic MVC Posted September 26, 2009 Author MVC Share Posted September 26, 2009 Then you can't do DD/5.1 audio over HDMI then. If you're somehow routing it through your TV it will be in what your TV outputs in, which is 2.0 stereo. That's why your DTS light isn't going on.Your 360 will need to do it over an optical cable. Just leave the optical cable in your 360, plug it into the receiver, and select optical output on NXE. Doesn't really matter as already pointed out in this topic, there's no audio benefit on the 360 to using HDMI over optical, for those that can it's just one less cable in your setup. Apparently there is some special HDMI connector that has an optical port port on it but I'm just using a generic HDMI cable. Right now the only optical cable that is plugged in is the one going from the receiver into the TV. I'll just hook the component back up or something.

Ahhh sorry I totally forgot the 360 doesn't come with a standard optical connection :( On the PS3 it's just a separate connection on the back for optical. Mines is just HDMI, but my receiver does HDMI input/output. Link to comment Share on other sites More sharing options...
neoadorable Posted September 26, 2009 Share Posted September 26, 2009 yes carmatic there are headphones like that, but i never can tell the difference compared to regular stereo, so i'm fine. Link to comment Share on other sites More sharing options...
carmatic Posted September 27, 2009 Share Posted September 27, 2009 Ahhh sorry I totally forgot the 360 doesn't come with a standard optical connection :( isnt the mod where you chop up the connector to expose the standard connections inside them one of the most famous things people do to their 360's? or am i confusing betwen this and something else...

Boz Posted September 27, 2009 Share Posted September 27, 2009 (edited) HDMI is only beneficial on a technical level when considering HD audio/7.1, 360 can't do HD audio.Optical/HDMI are the same for DTS/DD 5.1/AC3 5.1, so the only benefit is less cabling. There you go.. Correct answer overall. The technical answer is actually that HDMI cables allow you higher bandwidth as Dolby Digital/DTS can do away with optical because optical offers required bandwidth for those audio codecs. Optical (Toslink) cable has only enough bandwith to transmit 2ch PCM sound and your receiver does the decoding so that how you get 5.1 DTS/DD audio. When you are dealing with 6.1 and 7.1 channels and HD audio streams that go over 1.5mbps (DTS-MA) can go up to 24mbps optical cable can't do it. So you need HDMI 1.3. Actually Toslink originally supports 3.1 Mbit/s transfer rate but they've upgraded it to 125 Mbit/s now but it can't carry video so it kind of makes it useless. Also those new revisions of Toslink are very expensive and they again suffer from the same problem as older versions (the one you will mostly buy at the regular store) suffer and that's that the longer optical cable is the greater loss of quality it will suffer from. That's why you will see very short Toslink cables and if you need longer ones almost every tech person will recommend a booster for maximum quality. So HDMI is the new standard that is more versatile and why it became popular. So in essence HDMI CAN transmit Dolby Digital with no problems. The 1.2 designation is that it just doesn't have deep color which 1.3 has and it can support DTS-MA/TrueHD which 1.0/1.1/1.2 HDMI can't. Well HDMI 1.2 can support DTS-MA/TrueHD but only if you set your Blu-ray player for example to decode internally to multichannel PCM and then send it via HDMI 1.2 cable to your receiver. 1.2 can't bitstream DTS-MA/TrueHD unfortunately. Deep Color is less important than DTS-MA/TrueHD support in 1.3 so for Xbox 360 you don't really need 1.3 cable as the box itself doesn't support HD audio codecs. In any case 1.0/1.1/1.2/1.3 and 1.4 HDMI all support DD/DTS. What you need to do is have 2 HDMI cables. One HDMI cable will go from your receiver output and you will use Xbox 360 HDMI connection to go directly to one of your receiver inputs. This way when you want to play Xbox 360 you will switch you will set a preset on your AVR remote to Xbox 360 (where you defined that Xbox 360 preset works with HDMI input #1 for example) and your output will always output the picture to your TV. This way you can have multiple sources in input HDMI jacks of your reciever and only one output to your TV. Btw, Audioboxer (AC3 is Dolby Digital :) ). E-AC3 is Dolby Digital Plus. Also, Mystic NEVER EVER buy HDMI cables at retail it's a widespread rip off even if it's not Monster crap. You go to http://www.monoprice.com and get the cables there for dirt cheap. The cables are great and no lesser quality than what you would buy anywhere else but you can get HDMI cables for like $4.

That will work, but one of the gripes with that method is if you change the TV input selection, say to switch to regular TV, or to another console (if you have a Wii/PS3), and then you switch back to the 360, it'll reset the console.

I've been buying from Monoprice for a while now, great prices there! Because I'm so frugal, I'll probably just end up going back to component and doing optical that way instead of spending $10 more dollars on the special HDMI optical connection.
