Advertisements One oddity I recently discovered is that dialog on all live channels (Sling, Locast) is in stereo with no audio produced from the center channel (and this is with my Yamaha receiver the audo signal is Dolby Digital+ Surround.) All movies streamed from Netflix, HBO Max, etc, the dialog correctly comes out the center channel. When I had Xfinity, I had the opposite problem. Too much of the dialog on live TV (if not all of it) came out only the center channel. While technically maybe that's the correct way to do it, it sounds much better if a small portion of the dialog (for like news, etc) is also sent to the left and right speakers - at least that's my personal preference if having a slightly wider sound field for the dialog on live TV. See for yourself, play something on Sling like the News and you'll see the center channel is basically silent.
