Hi @5werve 

Welcome to the HP Support Community. Thanks for bringing this to our notice.

I see that you are facing HDMI port-related issues on your system. Do not worry, we are here to fix it.

May I know from when are you facing this issue?

Did you make any hardware or software-related changes to it?

HDMI has its own audio driver separate from the audio system of the computer (Sigmatel, IDT, or Realtek ). It is incorporated into the graphics card's driver, so first, make sure you have the newest version of your graphics card driver. On models with Intel graphics, the HDMI audio driver will appear in the Device Manager as "Audio device on high definition audio bus.

Connecting the laptop to the TV:

"Every time you try a different solution you should reboot the computer using the following procedure. HDMI audio is
pretty picky and doesn't seem to work well without a reboot, in general.

Also, the computer should be off when connecting the HDMI cable.

1 Turn off the computer and TV.
2 Connect the HDMI cable to the computer and TV.
3 Then turn the TV on. Adjust its setting to receive HDMI audio.
4 Next, turn on the computer to allow it to detect the connection to the TV.
5 Go to Start>Control Panel>Sound>Playback tab. Select the HDMI device as the default device. Click the Set Default button, and then click OK."

You may also try the steps below and let me know: 

• Turn on computer with HDMI plugged in
• Go to control panel -> sound / audio. This opens the Sound & Audio Device
• Properties window Go to Audio Tab. Sound Playback likely reads 'Realtek HD'.
• Unplug the HDMI cable from the computer. Wait 5 or 10 seconds and plug back in.
• Now in the same Souund Playback dropdown you'll hopefully see HDMI Device.
• Select that, and click Apply. Now, you should have audio going through to your TV.

Let me know.

Hope this helps! Keep me posted.
