Hi Jose,

You can follow the below methods and check if it helps:

Method 1: By default Windows does not route sound over the HDMI output. To change this we need to change the settings in control panel.

Note: This will turn off sound from the speakers or normal audio output on the laptop. To get that back you will have to reverse this process.

1. Press Windows key + X 
2. Click on "Control Panel"
3. With the Control Panel in "Control Panel Home" view please click on "Hardware and Sound"
4. Where it says "Sound" in green letters there are three options below that are in blue click on "Manage Audio Devices"
5. This will bring up a window labeled "Sound"
6. On the "Playback" tab there is listed the sound options available to you. One should read "Digital Output Device (HDMI)" Click on that.
7. There should now be a check mark on that option, make HDMI sound output as default .
8. The Sound should then play through your HDMI hookups to the TV.

Method 2: Update the Sound driver

1. Press Windows key + X key when you are at desktop.
2. Select Device Manager.
3. Double-click Sound driver from the left panel to Update. 
4. Right-click the device, and click Update driver Software
5. Windows will prompt you to confirm the device’s removal. Click OK to remove the driver.
6. Then reboot your computer and it should work fine.

I hope this helps.
