You've connected your laptop to the TV via HDMI. The picture displays perfectly. But when you hit play, nothing comes through the speakers. Sound's still pouring out of your laptop instead. This is one of the most frustrating tech problems because everything looks like it should work, yet it simply doesn't. The good news? You'll almost certainly fix this today without replacing anything or calling anyone.

TL;DR

HDMI audio not working on TV from laptop usually means Windows hasn't set the HDMI output as your default device. Right-click the speaker icon in your system tray, select Open Sound settings, and choose your TV's HDMI output as the default device. If that doesn't work, power cycle both devices, enable hidden HDMI devices in Device Manager, or update your graphics drivers. Most cases resolve in under 15 minutes.

What Causes HDMI Audio Not Working on TV from Laptop?

Understanding why this happens helps you pick the right fix. HDMI carries both video and audio through a single cable, but they travel on separate signal paths inside that cable. When you see video but hear nothing, it means the video signal arrived fine but the audio signal didn't, or Windows isn't routing audio to the HDMI port at all.

Windows treats HDMI audio as just another playback device, identical to your built-in speakers or headphones. By default, it doesn't automatically detect and prioritise your TV's speakers. So even though the HDMI connection is active and working, Windows keeps sending sound to wherever it sent audio last time (usually your laptop speakers). Your TV is ready to play audio through HDMI, but Windows never tells it to.

Graphics drivers add another layer of complexity. HDMI audio doesn't rely on your traditional audio driver, it depends entirely on your graphics card driver. Whether you have Intel, NVIDIA, or AMD integrated graphics, that driver controls the HDMI audio interface. If it's outdated, corrupted, or disabled, Windows can't communicate with your TV's audio input at all, even though video works perfectly through the same cable.

Physical problems do happen occasionally. A loose connection, a damaged HDMI cable, or bent pins inside a port can break the audio signal while leaving video intact. And sometimes Windows hides HDMI audio devices after a driver update or system configuration change, rendering them invisible and inaccessible until you manually enable them again.

HDMI Audio Not Working on TV from Laptop: Quick Fix

1

Set HDMI as Default Audio Device Easy

  1. Power cycle both devices
    Power off your laptop completely. Turn off your TV and unplug its power cable from the mains for 30 seconds. This clears temporary hardware states that sometimes prevent proper HDMI handshake. Firmly reconnect the HDMI cable at both ends, push it in until you hear or feel a click. Plug the TV back in and power it on first, then start your laptop. Wait for Windows to fully load.
  2. Verify display mode
    Press Windows key + P on your laptop. You'll see display options on the right side. Select Duplicate or Extend mode. Do not select PC screen only, that disables the HDMI connection entirely. Confirm your TV is now displaying your laptop screen.
  3. Set HDMI as default audio output
    Right-click the speaker icon in your system tray at the bottom-right corner of your taskbar. Select Open Sound settings. Under the Output section, you'll see a dropdown menu showing your current audio device (probably "Speakers" or "Headphones"). Click this dropdown. Look for an option labelled HDMI Output, Digital Output, or your TV's model name. Select it. Then click Set as default.
  4. Test audio playback
    Open YouTube or any video file on your laptop. Play something with obvious sound (a music video, a movie trailer). Listen carefully, is sound coming from your TV speakers now, or still from your laptop? If it's coming from the TV, you're done. Adjust your TV volume if needed.
✓ If audio now plays through your TV, the problem is solved. This works 80% of the time because the HDMI connection was always working, Windows just needed to be told to use it.

Enable Hidden HDMI Audio Devices Easy

  1. Open Device Manager and show hidden devices
    Press Windows key + X and select Device Manager. In the menu bar at the top, click View. You'll see a checkbox option for Show hidden devices, click it. This reveals devices that Windows has disabled or hidden, which is often why HDMI audio becomes invisible.
  2. Find and enable hidden HDMI audio devices
    Expand the Sound, video and game controllers category by clicking the arrow next to it. Look for any device names that are greyed out or faded. Common names include High Definition Audio Device, NVIDIA High Definition Audio, Intel Display Audio, or AMD High Definition Audio Device. Right-click any of these hidden devices and select Enable device. Windows will initialise the device, this takes 10-15 seconds. You may see a brief notification when it completes.
  3. Set the newly enabled device as default
    Once the device is enabled, go back to Sound settings (right-click speaker icon, select Open Sound settings). Under Output, the dropdown menu should now show your HDMI device as an available option. Select it and click Set as default.
  4. Test audio and adjust format if needed
    Play a video on your TV. If audio works, you're done. If not, stay in Sound settings and click Device properties for your HDMI output. Click Additional device properties, go to the Advanced tab, and in the Default Format dropdown, select 16 bit, 48000 Hz (DVD Quality). Click Test, then Apply. Some older TVs don't support higher sample rates, so this format works with nearly everything.
✓ This fixes 50% of cases where the HDMI device exists but Windows has hidden it. Audio format adjustment often resolves the remaining 30%.

Advanced HDMI Audio Not Working on TV from Laptop Fixes

At this point, outdated graphics drivers are almost always the culprit. These drivers control HDMI audio on the hardware level, and Windows can't route audio through HDMI if the driver is corrupted or months behind. You may also discover a faulty cable or port that's been causing the problem all along.

Update Graphics Drivers Intermediate

  1. Update drivers through Device Manager
    Open Device Manager again (press Windows key + X, select Device Manager). Expand Display adapters. You'll see your graphics card, it'll say something like Intel HD Graphics 620, NVIDIA GeForce GTX 1650, or AMD Radeon RX 6700. Right-click it and select Update driver. Choose Search automatically for drivers. Windows will download and install any available updates. If an update is found and installed, restart your laptop immediately. If no update is found, proceed to the next step.
  2. Check Windows Update for optional driver updates
    Open Settings (press Windows key + I). Go to Windows Update > Advanced options > Optional updates. Look for any driver updates listed here, particularly graphics or audio drivers. Select them and click Download and install. Restart your laptop.
  3. Check and verify HDMI connections
    While the driver update processes, inspect your HDMI cable for visible damage, bent pins, kinks, fraying. Try a different HDMI cable if you have one. Disconnect and firmly reconnect the cable at both ends. If your TV has multiple HDMI ports, try a different one (TV ports sometimes fail individually). Same with your laptop if it has multiple HDMI ports.
  4. Reinstall graphics drivers cleanly (if updating didn't work)
    If driver updates didn't solve it, try a clean reinstall. In Device Manager, right-click your graphics card and select Uninstall device. Tick the checkbox for Attempt to remove the driver for this device if it appears. Click Uninstall. Restart your laptop. Windows will automatically reinstall the driver from its built-in library. Alternatively, download the latest driver directly from your graphics card manufacturer's website (Intel Driver Support Assistant, NVIDIA GeForce Experience, or AMD Radeon Software) and install it manually. This takes 10-15 minutes.
  5. Reconfigure HDMI audio and test
    After the driver reinstall completes, repeat the steps from Solution 1: right-click the speaker icon, open Sound settings, select your HDMI device as default. Test audio playback. If your TV has an audio input menu, verify that HDMI is selected as the input source on the TV side as well.
✓ Graphics driver updates fix HDMI audio issues in about 50% of cases where previous solutions failed. This is because Windows can't communicate with HDMI hardware without the correct driver.

Run Windows Audio Troubleshooter and Test with Different Hardware Intermediate

  1. Run the built-in Windows Audio Troubleshooter
    Open Settings (Windows key + I). Go to System > Troubleshoot > Other troubleshooters. Look for Playing Audio in the list. Click Run next to it. Windows will scan your audio configuration, test playback, and automatically apply fixes if it finds problems. This often catches misconfigured settings that manual troubleshooting misses. Follow any on-screen prompts and let it complete fully.
  2. Test with a different HDMI cable
    Borrow a different HDMI cable from someone if you can, or pick up an inexpensive one. Cheap cables ($2-3) sometimes fail, but you'll know for certain if the cable is the problem. Connect it and test audio. If it works with a different cable, your original cable is faulty, replace it.
  3. Test with a different TV if possible
    If you have access to another TV, connect your laptop to it. If audio works fine on the second TV, your original TV may have a faulty HDMI input or disabled audio input settings. Check your first TV's menu for audio input options. If audio fails on both TVs, the problem is your laptop, not the TV.
✓ If the troubleshooter finds and fixes issues automatically, audio often returns immediately. Different hardware testing isolates whether the problem is cable, TV, or laptop.

Preventing HDMI Audio Not Working on TV from Laptop

Once you've fixed this, keep it fixed. Most HDMI audio problems stem from driver neglect or loose connections that happen over time. A few habits prevent 90% of future issues:

Use quality cables and connectors. Cheap HDMI cables degrade quickly, especially if you move them frequently. Invest in HDMI 2.0 or newer certified cables and avoid unnecessary extensions or adapters. Store cables carefully, kinks and bent pins are a slow death sentence for HDMI.

Keep drivers current automatically. Enable automatic Windows Update in Settings > Windows Update > Advanced options. This ensures your graphics drivers update silently without you having to remember. Alternatively, use your graphics manufacturer's driver tool (Intel Driver & Support Assistant, NVIDIA GeForce Experience, or AMD Radeon Software) to auto-update when needed.

Set HDMI as default immediately after connecting. Don't wait to see if it works automatically. The moment your TV displays your laptop screen, right-click the speaker icon and set HDMI as your default playback device. This takes 30 seconds and prevents the annoying situation where you discover audio doesn't work mid-presentation.

Power cycle regularly. Every week or two, fully power off your laptop and TV (not sleep mode). Unplug the TV for 30 seconds. This clears temporary hardware states that sometimes corrupt HDMI handshake. Many technicians do this as a preventive step, not just when troubleshooting.

Clean HDMI ports quarterly. Dust accumulation inside ports breaks connections slowly. Use compressed air (a can with a straw) to blow out debris from both your laptop and TV's HDMI ports. Do this when you notice the connection feels loose or audio cuts out intermittently.

Label everything and test before you need it. Write 'HDMI 1' or 'HDMI 2' on your TV's ports and on your laptop. When something breaks, you'll know exactly which port you used before. Test your HDMI audio setup a few minutes before any important presentation or meeting, never rely on it working without a quick sound check first.

HDMI Audio Not Working on TV from Laptop: Summary

HDMI audio not working on TV from laptop is almost never a hardware failure waiting to happen. It's almost always Windows routing audio to the wrong device, a hidden driver, or a disconnected cable. Start with the quick fix, setting HDMI as your default audio device. If that doesn't work, enable hidden devices in Device Manager or update your graphics drivers. Over 95% of cases resolve in under 30 minutes with one of these steps. The few that don't usually involve a faulty cable or a TV port that's failed, both of which you can diagnose by testing with different hardware. Keep your drivers current, use quality cables, and set HDMI as default immediately after connecting, and you won't see this problem again.

Frequently Asked Questions

The most common reason is Windows defaulting to your laptop speakers instead of automatically routing sound through HDMI. Other causes include faulty HDMI cables or connections, outdated graphics drivers (which control HDMI audio, not just traditional audio drivers), disabled HDMI audio devices in Windows, or incompatible audio format settings between your laptop and TV. Video often works fine because it uses a separate signal path than audio.

Start by restarting both devices and checking that your HDMI cable is firmly connected at both ends. Then right-click the speaker icon in your system tray, open Sound settings, and select your TV's HDMI output as the default device. If that doesn't work, open Device Manager, enable any hidden HDMI audio devices, update your graphics drivers, or adjust the audio format to 16-bit, 48000 Hz in the sound device properties. Most cases resolve with one of these steps.

Yes, this is extremely common across all Windows versions and laptop brands. It typically occurs because Windows doesn't automatically switch audio output to HDMI when you connect. The good news is that most cases are software-related rather than hardware failure, meaning they're fixable through simple settings changes or driver updates without replacing any components.

Absolutely. Over 95% of HDMI audio issues can be fixed without reinstalling Windows. Solutions include changing the default audio device in Sound settings, enabling hidden HDMI devices in Device Manager, updating or reinstalling graphics drivers, adjusting audio format compatibility, or replacing faulty cables. A full Windows reinstall is almost never necessary for this specific problem and should be your last resort.

Primary causes are incorrect Windows audio settings (laptop speakers selected instead of HDMI), faulty or loose HDMI cables and ports, outdated or corrupted graphics drivers, hidden or disabled HDMI audio devices in Device Manager, and incompatible audio format settings. Less commonly, BIOS settings may disable HDMI audio output, or physical port damage may prevent signal transmission. Video often works fine because it uses a different signal path than audio.
