I am getting video but not audio out of the HDMI port from the back of the pc

[604edc]

I am trying to stream from my pc to my computer to my tv through a receiver. Everything was working properly but now the HDMI is giving me the video but not the audio. I have tried different ports on the receiver but still no audio. any suggestions to start the audio would be appreciated. How do I see or test to find out if the HDMI port is not working as I have tried to update the drivers but still no sound.

Welcome to HP Forums,  

This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂

I see that your experiencing issue with HDMI no audio output,
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• When was the last time it worked fine?
• Have you made any hardware/software changes?

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix:

Firstly: let's perform a hard reset: Desktop 

Use the following steps:

1. If Windows is open, click Start and then click Shutdown.

   If Windows is not open and the computer is connected to a power outlet, press and hold the Power button on the computer until the computer shuts off.

2. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.

3. With the power off, disconnect the power cord from the back of the computer.

4. With the power off and the power cord disconnected, press the Power button on the computer for 5 seconds. The power light indicator on or near the Power button might turn on briefly but then go out.

5. Reconnect the power cord and press the Power button to turn on the computer, but do not connect any of the peripheral devices.

6. If a startup menu opens, use the arrow keys to select Start Windows Normally, then press Enter.

7. Reconnect each of the peripheral devices.

Next: 

1. Connect the HDMI cable to your computer and to your output device.

2. Right-click the Volume icon  on the taskbar, and then select Sounds or Playback Devices.

   

3. The Sound window opens. On the Playback tab, select Speaker/Headphone or Speakers and Headphones, and then click Set Default.

   NOTE: Use Default Devices for audio output devices such as headphones or speakers. Use Default Communication Device for making and receiving phone calls.

   

4. Select the output device connected with the HDMI cable, and then click Set Default.

   

5. Right-click the output device connected with the HDMI cable, and then select Show Disconnected Devices. The HDMI cable must be connected when it is configured.

   

6. To view all the available sound devices, right-click any device shown in the Sound window and select the Show Disabled Device and Show Disconnected Devices options.

Hope this helps! Keep me posted for further assistance.
