HDMI No Sound on TV: Fixes That Work

If your TV shows a picture over HDMI but no sound, the problem is almost always in the audio output settings, the cable, or the connected device—not the TV itself. This guide walks you through the most common causes and the exact steps to restore sound, starting with the quickest fixes.

Why HDMI Audio Stops Working

HDMI carries both video and audio in a single cable, but that audio path depends on several things lining up: the source device must be set to output audio over HDMI, the TV must be set to accept it, and the cable must have the bandwidth to carry the audio format being sent. When any one of those fails, you get a picture with silence.

The most frequent culprits are:

• Wrong audio output selected on the source device (e.g., laptop is set to its own speakers instead of HDMI).
• HDMI ARC/eARC port confusion—plugging into a non-ARC port when you expect audio return.
• Faulty or low-quality cable that can carry video but not the audio data.
• Handshake issues between devices that can be cleared with a full power cycle.
• TV mute or volume set to 0 on the specific HDMI input.

Quick Fixes to Try First

Before diving into menus, try these three things—they solve a surprising number of cases.

1. Unplug and replug the HDMI cable at both ends. This forces a fresh handshake between the source and the TV.
2. Power cycle everything. Turn off the TV and the source device, unplug them from power for 60 seconds, then plug them back in and turn them on. This clears most HDMI negotiation glitches.
3. Try a different HDMI port on the TV. If one port is damaged or has a loose connection, another may work fine. Also check whether the port is labeled ARC or eARC—if you’re using a soundbar, that matters.

If sound still doesn’t come back, move on to the device-specific settings below.

Check the Source Device’s Audio Output

Your laptop, game console, or streaming stick decides where to send audio. If it’s set to its own speakers or a Bluetooth device, the TV will stay silent.

On Windows 10/11:

1. Right-click the speaker icon in the system tray and select Open Sound settings.
2. Under Output, choose the device that says HDMI or the name of your TV (e.g., “LG TV� or “Samsung�).
3. If you don’t see it, right-click the speaker icon, choose Sounds → Playback tab, right-click the HDMI device, and select Enable if it’s disabled.

On macOS:

1. Go to System Settings → Sound → Output.
2. Select the TV from the list. If it’s not there, check the cable and the TV’s HDMI port.

On game consoles (PS5, Xbox, Switch): Go to the console’s audio settings and make sure the output is set to HDMI (not “TV speakersâ€� or “headphonesâ€�). Some consoles also have a setting for HDMI audio format—try switching between PCM and Bitstream if you’re getting no sound or static.

TV Audio Settings and HDMI ARC

Your TV also has an audio output setting that can override the HDMI input. If the TV is set to output audio to an external device (like a soundbar) but that device is off, you’ll hear nothing from the TV’s own speakers.

Look for these settings in your TV’s menu (names vary by brand):

• Audio Output or Speaker Settings—set to TV Speaker (or Internal Speaker) unless you’re using a soundbar.
• HDMI ARC/eARC—if you’re not using a soundbar, make sure ARC is disabled or set to Off. If you are using a soundbar, plug the source into the TV’s ARC-labeled port and enable ARC.
• Digital Audio Format—try setting to PCM instead of Bitstream or Dolby. Some TVs have trouble decoding certain formats from a source, and PCM is the most universally compatible.

Also check the TV’s volume and mute button—some TVs have independent volume levels per input, and it’s easy to have muted one input while others stay normal.

HDMI Cable and Port Issues

Not all HDMI cables are equal. Older cables (pre-High Speed) may not have the bandwidth for 4K video plus high-bitrate audio. If you’re getting video but no audio, try a different cable—ideally one labeled High Speed or Ultra High Speed (for 8K).

Also inspect the ports: bent pins, dust, or a loose fit can break the audio channel while video still passes. Try gently reseating the cable, and if you have another device, test the same port with it to isolate whether the problem is the TV or the source.

A common misconception is that a “cheapâ€� cable won’t carry audio at all. In practice, most cables carry audio fine; the issue is usually the handshake or settings. But if you’ve tried everything else, a quality cable is a reasonable next step.

When to Update Drivers or Firmware

On a PC, outdated graphics drivers can cause HDMI audio to disappear. The audio over HDMI is actually handled by the GPU’s audio controller, so updating your graphics driver (NVIDIA, AMD, Intel) often restores sound. You can update through the manufacturer’s software or the device manager.

For smart TVs and streaming devices, a firmware update can fix HDMI compatibility bugs. Check the TV’s settings for a Software Update option, and make sure your streaming stick or console is up to date.

Frequently Asked Questions

Why does HDMI show picture but no sound?

This usually means the video signal is being transmitted, but the audio is either not being sent (source device is set to a different output) or not being received (TV audio settings or port issue). It’s rarely a hardware failure—settings and handshake issues are the most common causes.

How do I make my TV play sound from HDMI?

Set the source device’s audio output to HDMI, make sure the TV’s audio output is set to its internal speaker (or to the correct soundbar), and check that the TV volume is not muted. A full power cycle of both devices often helps after changing settings.

Does HDMI cable affect audio?

Yes, but only if the cable is damaged or too old to carry the audio format. Standard HDMI cables carry 5.1 surround sound, but some very old cables may not support the latest audio formats. If you’re getting no audio at all, try a different cable to rule it out.

Why is my soundbar not getting sound from HDMI?

Make sure the source device is plugged into the soundbar’s HDMI input (if it has one) and the soundbar’s HDMI output goes to the TV’s ARC port. Then enable ARC on both the TV and the soundbar. If you’re using a non-ARC port, you won’t get audio return.

Can a faulty HDMI port cause no audio?

Yes. A bent pin or a loose connection can break the audio channel while video still works. Try a different HDMI port on the TV to see if the problem follows the port or the cable.

Why does my PS5 show picture but no sound on TV?

Go to Settings → Sound → Audio Output and make sure the output device is set to HDMI Device (not TV Speakers or Headphones). Also check the TV’s audio format setting—try PCM if you’re using a non-ARC port.

Still No Sound? Try These Last Resorts

If you’ve gone through all the above and still have silence, try these final steps:

• Factory reset the TV—this clears any stuck audio settings. You’ll need to set up your inputs again.
• Use a different source device—if another device works on the same port, the problem is with the original source’s hardware.
• Check for HDMI-CEC conflicts—sometimes CEC (which lets devices control each other) can cause audio routing issues. Try disabling CEC (often called Anynet+, Bravia Sync, or Simplink) in the TV settings.

In rare cases, the TV’s HDMI receiver chip can fail, but that’s uncommon. If you’ve tried multiple devices, cables, and ports, and none produce sound, you may need to contact the TV manufacturer’s support or a repair technician.
