This app is great. Works amazing. I have a Sony TV and used to suffer from the dreaded volume issue, but I fixed that by creating a keyboard/remote mapping for the STB volume down command. Once you set the portal volume to something lower, the problem goes away. Here we provide StbEmu (Free) V 1.0.5 for Android 4.0++ StbEmu
I have installed this app in my Sony TV running Android TV and found out that the TV volume goes up everytime I change channels! More annoyingly, increases the volume even when using a different input in the TV, like when playing PS4 unless I exit/force close stbemu app! Please fix it and I will certainly consider buying the app as it seems to be the best IPTV app to use on a TV!
