Are you frustrated with a silent screen when you connect your devices to your TV using an HDMI cable? You’re not alone. Many people struggle with this issue, wondering why they can’t hear any sound coming from their TV despite having a perfect video connection. In this article, we’ll explore the common reasons why sound may not play on TV with HDMI and provide you with actionable solutions to resolve the problem.
Understanding HDMI Connections
Before we dive into the troubleshooting process, let’s take a step back and understand how HDMI connections work. HDMI (High-Definition Multimedia Interface) is a digital audio/video interface that allows devices to transmit audio and video signals to a display device, such as a TV. HDMI cables can carry both audio and video signals simultaneously, making it a convenient and widely adopted standard.
When you connect an HDMI cable from a device (such as a Blu-ray player, gaming console, or computer) to your TV, the TV receives both the video and audio signals. The TV then processes the signals and displays the video on the screen, while passing the audio signal to its built-in speakers or external speakers connected to it.
