Windows 10: Is it possible to output just audio over HDMI from Windows 10 ?

I want to output uncompressed multi channel audio from my Windows 10 PC to my AV amplifier over HDMI.

I have it working, I've got my amp connected via HDMI using the integrated Intel GPU's HDMI port. I also have a separate AMD Vega 64 as my main GPU.

That all works, I get uncompressed multi channel audio showing up on the amp.

However that also means that the PC is extending a desktop to that HDMI output, if I plugged a display into the output of the amp I'd see a Windows desktop.

What I'd like to do is just send audio over that HDMI connection and not extend the desktop there. If I do this the sound device for that HDMI connection disappears, understandably.

I've tried forcing that sound device to be enabled again, with devcon, but it has no effect. In fact once I've stopped extending the desktop to that output the only way the sound device is enabled again is by rebooting.

So, is it possible to output audio over this HDMI connection without extending the desktop there as well ?

HDMI audio output to Sony TV

Hi,

One possible reason why your HDMI audio output was not working due to outdated drivers. To isolate your issue, kindly answer the following questions:

• Have you made any recent changes prior to this issue?
• Did you get any error messages when you tried to connect your computer to your TV?
• Have you tried updating your HDMI audio driver?
• What troubleshooting steps have you done so far?

We're looking forward to your response.

 

HDMI audio output problem

If you had read the web page
https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/no-hdmi-audio-output/7b5b4084-5e0e-4c52-befb-1564ca2fe57e, you would not have suggested the Realtek website for finding the driver. If you want more
information, you will be able to read the web pages from above. The software tool named audio10 does not work. It cannot be started. The issue is: “How do I get Realtek HDMI Output in the device manager?” This would really solve the problem.

 

Is it possible to play sound through headphones and HDMI output simultaneously?

Hi David,

I would like to inform that it is not possible to output sound through both the HDMI and the headphone jack simultaneously.

But you can watch video through HDMI and listen via headphone jack.

Follow the steps below.

• Right click on the speaker icon in the taskbar
• Left click playback devices
• Right click HDMI
• Select Disable.

Hope this information helps.
