How to completely disable the sound of applications on Xiaomi Smart TV: all ways

Xiaomi Smart TVs (Mi TV 4/5/6, Mi TV A Pro, Mi TV Q1/Q2, and others) often face the problem of intrusive sound from applications – whether it is advertising on YouTube, background music on Netflix or sound notifications from MIUI TV Launcher. Unlike smartphones, where it is enough to remove the sound at the push of a button, on Xiaomi TVs, this process may not be obvious: standard methods of volume control do not always work for individual programs, and some applications (for example, Prime Video or Disney+) ignore system settings.

In this article, we’ll look at 5 proven ways to turn off audio for both applications and globally — including hidden developer settings, ADB circumvention, and even radical measures like resetting your audio profile. Focus on PatchWall and MIUI TV, where the interface and paths to settings may differ, and if you’re tired of the TV turning on the audio at full volume or playing ads at full volume — read on.
