Yeah, cable channels are a mixed bag. If you leave it on Straight mode, some channels will only have audio coming from the fronts and sub if they are just broadcasting in two channel stereo and not DD 5.1. Having it set to Dolby Pro Logic IIx or DTS neo:6 will process sound into all of the speakers. Same goes for some streaming apps. Make sure the blu-ray player is set to bitstream. Then, check each disc for audio options. Some have dolby atmos and DTS HD Master Audio options. The dolby atmos tracks will playback as Dolby TrueHD. I find they sound better than the DTS tracks but some may prefer DTS.
