An HDMI cable carries both video and audio signal. Using one to connect your PC and TV allows your PC to act as a multimedia hub, where you can watch movies stored on your system or play your favorite PC games if you have the peripherals. Windows typically configures everything automatically when you make the physical connections. If it doesn't, you need to run through a few steps if you don't hear the PC sounds coming from the TV.
Connect the HDMI cable to one of the vacant HDMI ports on your TV. Connect the other end of the same HDMI cable to your PC. Switch the TV to HDMI mode using your TV's remote control to see your computer screen. If your computer displays a window to install a driver, wait for the driver to finish installing.
Right-click the "Speaker" icon on the taskbar next to the clock. Click "Playback devices" from the popup menu that appears.
Click the playback device with the "TV" icon and click the "Set Default" button. Click the "OK" button to apply the changes. Sounds coming your PC will now be routed to your TV's speakers.
- If you cannot find your TV in the list of playback devices, right-click anywhere within the box showing the list of playback devices and tick both the "Show Disabled Devices" and "Show Disconnected Devices." Then right-click the TV icon and click "Enable."
- If your TV still does not appear, update your audio drivers using Windows Update from the Control Panel.
- If no sound is coming out of the TV, check the volume by clicking on the "Speaker" icon on the taskbar and adjusting the slider upwards to increase the volume. Clicking the slider will automatically unmute the volume as well. Check your TV's volume too and make sure it isn't set to mute.
