Just picked up a Playbar from Amazon which is arriving today - been doing some reading around on the whole DD5.1 vs DTS support argument. I'm not precious over exactly what format my audio is in, but eventually I'll be adding 5.1 support by adding a sub and some rear speakers so I'm looking for the easiest/best way of achieving true 5.1 surround from my living room setup.
I have a Panasonic AS650B TV, hooked up to an Amazon Fire TV (new one supporting 5.1), and an LG BP556 blu-ray player. The playbar is replacing a Philips Fidelio B5 which I've had a lot of issues with, but it did take all the inputs and handle all the audio decoding etc seamlessly so I didn't need to worry about it at all.
So my main question is, how do I ensure that I get 5.1 surround whenever possible using my current setup? The manual for my TV states that there are 2 options for audio output via SPDIF - Auto and PCM. Auto states that DD, DD Plus, HE-AAC multi-channel are all output as DD bitstream, and DTS is output as DTS. Whereas PCM states that "Digital Output is fixed as PCM".
My understanding is that PCM can actually mean multi-channel 5.1, so if this is correct I take it the playbar should be able to handle this and sort it out with the surround speakers? If so, which option am I best to use do we think? I don't think many of my sources are DTS based, the Fire TV as far as I can tell is DD5.1, at least that's what always showed up on the Fidelio system as the input stream. I don't have many blu rays yet, but I take it this is down to the individual disc as to what format the sound is in, and so I can always make sure to buy DD versions if possible?
The only complication is that I'm potentially swapping the Fire TV for an NVIDIA Shield TV, as I'm fed up of the netflix bug on the Fire where it constantly needs the app re-installing and is a major pain in the ass. I also have an Xbox 360 that gets used occasionally for games, so hopefully that's supported as well, but not the end of the world if games are only in stereo.
Thanks in advance, looking forward to joining the sonos ecosystem!
