I've been using the Stb Emulator Pro which I downloaded from the Google Play Store. I don't use Kodi with my Pendoo X6 Pro boxes and I usually set my media player to IJK but sometimes use VLC Player. I did notice an occasional channel losing sound but it was momentary almost like dropped packets. I have a few older CSA93 android 6.0 and 7.1 boxes running the same IJK player and the VLC media player without any noticeable differences aside from a slight difference in picture quality. Not sure as to why, it might be because of the newer Android 9.0 pie or the difference in hardware on the Pendoo boxes but they are all set with hardware accelerated settings ? Crystal clear full HD with HDR on the LG Oled screen. Not sure why but even the Chinese channels especially CTV 1, 2, and 3 are good. British channels tend to be a bit touchy when it comes to video and sound but nothing lately. I do use all my other devices like the Samsung View, Blackview 9500 Pro cellphone and an Onda android with Stb Emulator Pro with mac settings and all set to Hardware Acceleration. It doesn't seem to matter which android version so long as its 6.0 or higher, they're all fine.
