I have it hooked up to the TV with HDMI, and from there the sound goes out to my soundbar via s/pdif, which has a sub and two rear satellites attached, giving me 5.1 surround.
All good so far. HDMI should deliver 5.1 sound from movie files, no issues (I have not tested it, yet).
With a few proprietary exceptions, S/PDIF only supports 2 Channel PCM. So the above configuration isn't going to work. You will be getting 5.1 into the TV and Stereo out via the S/PDIF. Unless your TV can encode the audio output to Dolby Digital, which would support 5.1 Channels but also lose some audio quality due to the compression used in Dolby Digital. I don't think TVs support encoding to Dolby Digital for the S/PDIF output. Also, your Soundbar would have to be capable of decoding Dolby Digitial. If it has a sub and two rear satellites it may have that capability.
What is the make and model of your TV?
Does your TV support ARC (Audio Return Channel) via HDMI?
What is the make and model of your soundbar?
What inputs are available? (HDMI, RCA, S/PDIF, etc.)
PS: An administrator may be kind enough to move this thread, rather than have you start another one. But if you don't get enough answers here, by all means post in the
other forum.
PPS: I may be wrong here. I just checked the spec for my Sony KD-65X9300D and it says of the S/PIF output connection:
DIGITAL AUDIO OUT (OPTICAL)
Digital optical jack (Two channel linear PCM,
Dolby Digital, DTS)
So the above will work if your TV supports the same functionality and you encode to Dolby Digital, and your Soundbar can decode Dolby Digital.
