For about the last month I've bee using the contour app on my iPad mini 4 in a room without a TV. When I used it this morning the audio is being decoded incorrectly. During the national morning news I get a low mix on the dialog/center channel making the selected volume too load during stereo or surround music bumps. Also during commercials many seem to have the voice over completely assigned to the center channel affectively muting it all together, other then the sound effects and background music. Just to check it wasn't a temporary problem I check the OTA signal and also tuned it with my cox feed on a TV and everything sounds normal in both situations. I downloaded the Contour app to my iPhone 6 running iOS 11.3.1 and had the same problem. I have, just this morning, updated the iOS on my iPad to 11.4 but with the same problem on the iPhone running the earlier iOS I think this may be a problem on the Cox streaming feed.
Does it happen if you put in earphones? Also, I assume you subscribe to Contour 2 right? Not Contour 1? Next, are you running 4.10 version of the app?
yes also with headphones, yes contour 2 service, version 184.108.40.2065 one wrinkle...I use a Tivo for my TV sets, however I was under the impression that the app worked directly from cox over the internet and not though my home converter box.
