Windows 10 HDMI No Sound on TV: Sending Audio Along With the Picture
Connecting a laptop to a television should deliver both picture and sound over one cable. With Windows 10 HDMI no sound on TV, the picture arrives and the audio stays on the laptop’s speakers, or goes nowhere.
HDMI carries audio as a separate stream that Windows treats as its own playback device. If that judolbet88 device is not selected or not working, the television stays silent.
The remedy is usually a single setting, though the graphics driver also plays a part.
Likely Reasons Behind the Problem
HDMI audio fails for these reasons:
- The laptop speakers are still set as the default playback device.
- The HDMI audio device is disabled or hidden.
- The graphics driver, which provides HDMI audio, is outdated or missing.
- The TV is muted, set to another audio input, or the cable is faulty.
Because HDMI sound is supplied by the graphics driver and not the normal sound driver, people often update the wrong one.
First Steps to Try
Pick the TV as the sound output.
- With the TV connected and showing the picture, click the speaker icon in the taskbar.
- Click the device name above the volume slider and choose the entry that names your TV or mentions HDMI, NVIDIA, Intel Display Audio, or AMD.
- Raise the volume in Windows and on the TV remote.
- Check that the TV is not muted and that its speakers are enabled in the TV’s menu.
- Unplug and reconnect the HDMI cable, or try another HDMI port on the TV.
Windows often switches output automatically, but not always.
If the Problem Continues
If the TV does not appear as a choice, look for the hidden device.
- Right-click the speaker icon, choose Sounds > Playback, right-click an empty space, and tick “Show Disabled Devices.”
- Right-click the HDMI or TV device, choose Enable, then Set as Default Device.
- Open Device Manager, expand Sound, video and game controllers, and check that the display audio entry is enabled.
- Install the latest graphics driver from NVIDIA, AMD, Intel, or the laptop manufacturer, choosing the full package that includes the HD audio component.
- Restart with the cable connected.
An adapter converting DisplayPort or USB-C to HDMI must itself support audio, which some cheaper ones do not.
Protect Your Data First
Turn the TV volume down before testing, because audio may start suddenly at a high level. When installing graphics drivers, do not untick the HD audio component. Keep a restore point in case the new driver causes display problems.
Wrapping Up
Silent HDMI is nearly always a matter of choosing the TV as the playback device or enabling it. If it is missing, a complete graphics driver installation brings it back.
