Windows 10: Audio output while connected with HDMI

I'm connected to a projector with an HDMI cable and want to use the audio output from the computer to connect to a local PA system. The default is that when HDMI is connected, the computer audio port is disabled. How do I enable it?

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One possible reason why your HDMI audio output was not working due to outdated drivers.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.

 

No HDMI audio output

I have connected the monitor X23T-1 from Fujitsu, which has built-in speakers, with my graphics card Nvidia Geforce GT 230 via an HDMI cable at both ends. I have installed the latest graphics card driver. In the OSD menu of the X23T-1 I have selected HDMI
Audio in the section Input. In the system control panel of Nvidia I have selected X23T-1 the HDMI audio device. In Windows 10 however I do not get the option of selecting an HDMI audio device even if I let display disabled and disconnected devices. I have
also installed the latest Realtek audio driver but in the Realtek HD Audio-Manager there is no HDMI output device. I know that the speakers, the cable and the graphics card work properly because they worked properly with another mainboard but I also know that
I had some difficulties to enable the audio sound over HDMI at that time but finally it worked but now I do not know how I made it. I also know that I need Realtek HDMI Output instead of Realtek Digital Output in the device manager but it is just not there.
Can you help me?

 

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.
