This problem is familiar to many owners of Mi TVs, Redmi Smart TVs and other series of the brand. The reasons can vary from accidentally pressing a button on the remote to a system failure. In this article, we will discuss all possible ways to turn on sound, from basic to advanced, including hardware methods and fault diagnosis.
