Windows 10: sound not transferring through hdmi when connected to external monitor

Sound not transferring through HDMI when connected to external monitor

:)

 

No sound when connected to external monitor

Hi Bill,

To fix this issue, you can try the steps below:

• Plug in both ends of the HDMI without the laptop on.
• Turn the external monitor on and set to HDMI screen.
• Boot up your laptop from a shutdown position (not restart).
• Your laptop will now recognize the external monitor and will acknowledge its presence.
• Right-click the speaker icon on the task bar and choose
  View Volume Controls.
• Set TV as default.
• Click Apply, then click Ok.

You can also refer to the article in this

Let us know how it goes.

 

After update today, external HDMI monitor has no sound and speaker no longer listed as audio device

My Windows 11 22H2 updated today with

2022-09 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems (KB5017389) and 2022-09 Cumulative Update Preview for .NET Framework 3.5 and 4.8.1 for Windows 11, version 22H2 for x64 (KB5017271).

Now my external HDMI sound is gone.

From task tar, click sound icon, only see Lenovo laptop's built-in speaker listed (Realtek Audio).

Before I can see my HDMI monitor's speaker listed there.

Shutdown laptop and leave external monitor on does not help. Disconnect HDMI cable, power off/on monitor did not help either.

Audio of Device Manager does not list external HDMI monitor's speaker listed there neither.

I especially suspect KB5017271 caused the problem. Was updated KB5017389 first and it seemed was fine with external HDMI monitor speaker (but not 100% sure) which was updated first.

 

dual monitors stops sound

Hi David,

Thank you for posting in Microsoft Community.

To assist you better, I suggest you to answer the below questions.

• When will the sound disable, when playing through main monitor or the extended monitor?
• Did you try enabling the sound from the sound drivers and check if it helps?
• Since from when are you facing this issue?

This issue causes because the monitor automatically takes the HDMI sound as the Default input. Disable and enable the speakers and check if it helps.

I suggest you to try the below steps and check if it helps.

• Right click on the volume control and then
  Properties,
• When you connect the HDMI it becomes the default output device, even though it has no speakers.
• You need to change this back to "Speakers" and set as default.

Hope this helps. Keep us posted to help you better.
