Is it a bandwidth issue... S/PDIF (optical/coaxial/toslink) is only capable of 5.1 DTS/DD, or 2.0 96khz PCM (uncompressed) streaming. The lossless codecs have what's called a 'core' component which is either DTS for DTS-HD HR/MA, or DD for TrueHD. The device/software decoding the track needs to see how it outputs the audio, so when SPDIF is being used, it will automatically output the 'core' component of the HD lossless track.
So, regardless of the HD track being TrueHD or DTS-HD (MA or HR), the 'core' component will be output. In this particular case of the E601i, it will not pass DTS via SPDIF, which is the issue Matt is facing.
You said you only have 1 optical-in, does the AVR have coaxial inputs as well? If yes, you can get an optical-to-coaxial converter and plug the other cable to the coaxial-in.
I really think you should put $150-$250 and get a low-end HDMI 1.4 receiver, this will eliminate cabling issues and heartache
There's no way to stop technology/advancement
Yes sir, you are absolutely correct. My AVR has optical AND coaxial input available so I will try hooking my BD player via coaxial and that should solve my problem.
I've Googled the hell out of this subject and am slowly becoming an expert in the area of lossless codecs PCM bandwith SPDIF Toslink stuff. Did you know that the Toslink cable/connection was invented by Toshiba in 1983? Fascinating!
Anyway... for all the reading I've done it looks like there are two barriers at play here with regards to not getting certain 5.1 sources from my BD player: 1. Toslink will not support 7.1...but it SHOULD support 5.1 and pass it from my tv to my AVR if not for... 2. Vizio does not pass through 5.1 DTS-HD HR/MA
I actually have a Vizio 5.1 soundbar on the way to my house as we speak (thanks, Amazon!). Aaaaand I bought the damn thing BEFORE I hit this website and realized the 5.1 limitations of this tv. Yes, a low-end HDMI receiver would solve my issues...but I never would have bought a soundbar if I had known all of this. I would have stuck with the speakers I already have.
And guess what my new fancy Vizio 5.1 soundbar is NOT going to have?? A freaking HDMI port! But it does have a Toslink port AND a coaxial port.
So here's what I plan on doing... I will continue to run all devices through the TV that will pass through 5.1 without problems (cable box, Xbox, etc), since it seems everything coming through is DD or TrueHD. Then I will use Toslink to connect the Vizio TV to the Vizio soundbar. For my BD player I will use coaxial direct to the soundbar to preserve 5.1.
I'm thinking this should work...but who the hell knows ha. I'll find out Wednesday when it gets here.
Good work, everyone! Thanks for your help and suggestions!
