Everyone has different setups, some play everything through their TV, some use sound bars, some use receivers with a complete sound system. We also use many different streaming devices. What works for you, may not work for someone else, the same goes with what works on one device may not work on another. You will just have to try changing some settings in TiviMate and your streaming device. Not everyone will achieve the same results with the same settings. It could also be something as simple as having to replace your HDMI cord.
Go to Settings/Playback, here you have several options to choose from.
Audio Decoder/Video Decoder; if you're having issues, try changing to software/hardware.
Auto Framerate; you can try turning it on and see if it helps you. If you are experiencing a black screen for a few seconds when changing channels, you may want to have this off.
Audio Pass-through; toggle between on/off.
This is also where you would turn on external players. This only allows for an external player, you must have alternate players installed on your device, then when you try to play something, you'll get a pop up asking what player you want to use.
If none of this helps, you'll need to go to your device settings and change your Audio/Video settings on that.
