I posted this in another thread, but I'll post it here. It might help those who want to get surround from their 2.0 HBO Go feed:
So I downloaded the HBOGo app for the PS4 the other day, so when I got home last night, I thought I would watch some HBOgo before going to bed. However, when I played anything through Go, it only came out in stereo format. My PS4 is set to Bitstream(Dolby). Multichannel codecs work with BD/DVD, Netflix and Amazon do DD+ just fine. However, HBOGo is locked to 2 channel content, even though my receiver is reading Dolby Digital.
When I cycle through my receiver's surround options (a Denon AVR1912), it gives me Stereo, DD, Multichannel stereo and Mono. Dolby Digital is only outputting 2 channels. The other options perform as advertised. I actually had to go to the Music surround options and switch to "Matrix", which is Denon's version of DD/DTS style matrixing algorithms which takes a 2 channel source and up mixes it to 5 channels. Once I switched to Matrix, I got the surround separation I was looking for. Center channel blazed to life with all of the dialogue. Main L/R still had plenty of content, and there was plenty of stuff going on in the surrounds. Thanks Denon.
But no thanks to HBO. Why is their app so gimped in the sound department? Both Netflix and Amazon work just fine with the PS4. Surround is so ubiquitous these days, there's no excuse not to include it as a basic feature of your streaming service. For shame!
