Many people connect their laptops to their TVs to watch movies or play games on a larger screen. However, sometimes the HDMI cable connection does not transmit audio from the laptop to the TV. To resolve this issue, you can try using an additional standard sound cable from the audio output on your laptop to your TV. Alternatively, you can use the function keys on your laptop (e.g. FN+F7) to switch to display on both the laptop and TV, which should allow sound to play through the TV. If you have a newer laptop model that does not have an HDMI port, you will need an HDMI adapter to connect to your TV.

What You'll Learn
Ensure your HDMI cable is connected to the correct port
If you're trying to have your laptop sound play through your TV, it's important to ensure that your HDMI cable is connected to the correct port. This process involves several steps to ensure a proper connection and troubleshoot any potential issues.
First, check that your HDMI cable is securely connected to both the laptop and the TV. Loose connections can often cause issues, so make sure the cable is plugged in snugly to both devices. If your device has multiple HDMI ports, try using a different port on each device.
Next, verify that your display settings are configured correctly. On your laptop, access the display settings and ensure that the output is set to extend or duplicate the display, rather than just the laptop screen. You may need to adjust the resolution and refresh rate settings on your laptop to match those of your TV. Check your TV's input settings as well, ensuring that the correct input source is selected to match the port connected to your laptop.
If you're using an adapter, such as a DP to HDMI adapter, ensure that it is securely connected and compatible with your devices and the resolution and refresh rate you require.
Additionally, check your graphics drivers and ensure they are up-to-date. Outdated or corrupted drivers can cause connectivity problems. If necessary, try uninstalling and reinstalling your graphics driver.
By following these steps, you can ensure that your HDMI cable is connected to the correct port and troubleshoot common issues related to HDMI connections between your laptop and TV.

Check your laptop's control panel settings
To have your laptop's sound play through your TV, you will need to adjust some settings on your laptop. This can be done by accessing the laptop's control panel.
First, connect your laptop to your TV using an HDMI cable. Once the devices are connected, go to the Control Panel on your laptop. From there, navigate to the "Sound" or "Hardware and Sound" settings. Within these settings, you should see a list of playback devices. Look for the HDMI option, as well as the "Speakers/Headphones" option. Select the "Speakers/Headphones" option and click on "Set Default". This will ensure that the audio is routed through the TV's speakers.
If you are unable to locate the HDMI option in the playback devices list, you may need to enable it. To do this, right-click on the speaker icon and select "Playback Devices". Then, right-click on the speaker option and select "Show Disabled Devices". If HDMI is listed here, enable it and set it as the default playback device.
Additionally, you may need to adjust your TV's settings. Some TVs have a setting that allows you to send audio to an external source or through the TV speakers. Try disabling the TV speakers and sending the audio to an external source, such as a receiver or your laptop.
If you are still encountering issues, it may be related to your adapter or HDMI cable. Try using a different adapter or cable to see if that resolves the problem. Additionally, ensure that your TV is up to date with the latest system software, as outdated software can cause audio issues.

Use a DP to HDMI adapter
DisplayPort (DP) to HDMI adapters can be used to connect a laptop to a TV and transmit audio and video. However, it is important to note that not all laptops have DisplayPort outputs, and some older laptops may require a DVI-to-HDMI adapter instead.
To use a DP-to-HDMI adapter, follow these steps:
- Connect the DP-to-HDMI adapter to your laptop's DisplayPort output.
- Use an HDMI cable to connect the adapter to one of your TV's HDMI inputs.
- Ensure that the HDMI cable is securely connected at both ends.
- If your TV has multiple HDMI inputs, select the appropriate input using your TV's remote control or input buttons.
- On your laptop, go to the Control Panel or Sound settings.
- Look for the "Playback Devices" or "Manage Audio Devices" option and click on it.
- You should see a list of audio devices, including your TV or HDMI output.
- Right-click on the HDMI output or TV speakers and set it as the default audio device.
- Play some audio on your laptop to test if the sound is now playing through your TV.
If you are experiencing issues with audio playback, it may be necessary to update your audio and video drivers. Additionally, ensure that your TV is set to the correct input and that the HDMI cable is functioning properly.
It is worth noting that while HDMI is the most common and straightforward method for connecting a laptop to a TV, wireless options are becoming increasingly popular for their convenience. The best connection method will depend on your specific devices, intended use, and personal preferences.

Connect an additional audio cable from your laptop to your TV
If you want to connect your laptop to your TV using an audio cable, you can use an HDMI cable, which is the most common and straightforward way to connect a laptop to a TV. HDMI (High-Definition Multimedia Interface) is capable of transmitting both high-quality digital video and audio signals.
However, if you are connecting your laptop to your TV using an HDMI cable, but the sound is only playing through your laptop, you can try connecting an additional standard audio cable from the audio output on your laptop to your TV. You may need to tinker with the audio input and output settings to get it working.
If you are using a Windows laptop, you may need to change the default playback device in the Control Panel/Sound settings. Right-click to show disabled devices and select the HDMI output as the standard playback device.
If you are using an adapter, such as a DP to HDMI adapter, you may need to update your HDMI driver or try a different adapter.
For wireless connections, you may need to manually change the audio output in your laptop's sound settings.
