I installed HBO Go on my Samsung Galaxy Tab 4 and it installed and works ok. However I get no sound at all, just the video. I tried the same Go on my home pc and the video and sound work fine. I checked the sound on my Android and it is all the way up. All other apps (music player, etc) work fine. It is just with HBO Go that I get no audio at all. Can anybody give me some idea of what may be wrong? I notice that on my pc version, the Go player has sound controls. The android tablet version has no sound controls, but my android sound bar opens at the top of the player and it shows all the way up. Any help would be appreciated.
