No sound from tv when hdmi is connected

[LordRahl420]

I have an HP 15 f039wm laptop running Windows 10 (64 bit) and when I connect my hdmi cable from laptop to tv, I get video but no sound.  I've tried the following:

1.  Right-clicked on speaker and opened Sound window and clicked on playback tab.  The only option was for

      the built in speakers

2.  Turning laptop and tv off, connecting hdmi then turning pc on first then the tv.  I even reversed it and turned

      the tv on first,  Nothing

3.  Restarting and shutting down pc

I cannot figure out what to try next.  I'm pretty good with computers but this problem eludes me.  All software and drivers are up to date,  Somebody please help!

Hi! @LordRahl420,

Have you tried checking with a different HDMI cable?

Have you increased the volume on your TV?

Please try few steps mentioned below.

If the HDMI device is not set as default device, you cannot hear the sound from HDMI output. Follow steps below to set the HDMI device as Default Device:

1) Right-click on sound volume icon in the lower right corner of Windows. A context menu will pop up.
2) Click Playback devices.

3) Right-click and select show disabled devices.

4) Check if the HDMI option is listed now.
5) If the HDMI option is listed In the Playback tab, select Digital Output Device or HDMI option. Click Set Default and click OK. Then the HDMI sound output will be set as default.  
If you do not see the Digital Output Device or HDMI option in the Playback tab, right click on the blank place, then click Show disconnected devices and Show disabled devices on the context menu. Then set it as default device.

 
Open the Device Manager in Windows 10.
Navigate to Sound, video, and game controllers.
Now connect your PC to TV using HDMI connection.
This will show some “HDMI Audio” related driver under the above section.
Now right-click that item and UNINSTALL it.
Now right-click Sound, video, and game controllers and select “Scan for hardware changes“.
This will install a typical driver which is something like this – “Device with HDMI AUDIO OUTPUT SUPPORT”.

Also, try the steps recommended below.

• Control Panel, Sound, Manage Audio Devices
• The Soundbox will pop up.
• On the playback tab, you should see two icons. One for your laptop speakers, one for the external monitor/TV.
• Double click on the Laptop speakers, then click "Set Default" button on the bottom.
• The Laptop Speakers will be "Checked".
• Select OK and exit.
