Question I'll share this -- Following my upgrade of Win 11 to version 25H2

[BonzaiDuck]

The particular machine was a "Media PC" feeding an HDMI port on my Sony Bravia TV.

Never had this problem until after disconnecting then reconnecting cables to the system -- including the HDMI cable. It also was "discovered" after the successful upgrade of Win 11 to version 25H2. [I also had initial networking problems -- this system was a backup "server" for files on my front-end systems. Those difficulties have been resolved by "re-sharing" the relevant folders.]

Suddenly, I have video to the Sony but no Audio coming through the HDMI.

I can suspect: The HDMI cable; the HDMI port on the Bravia, the Intel Graphics HDMI on the motherboard. So far I haven't uncovered any "driver" problems. But experience of people in forums and elsewhere -- including your "Google AI" in response to a simple query -- suggest it is quite possible that the HDMI cable was just damaged from disconnecting and re-connecting.

I have a fix for this if the INtel Graphics on the motherboard has taken a dump, or something with the HDMI port.

We will get to the bottom of it. I just have undertaken too much in giving my computers and the home network a makeover. Well, we'll start with the cable. I ordered two $5 high-end 10ft HDMI's -- arriving tomorrow. I post this because it may inspire the curious or the knowledgeable to share their thoughts.

We're going to sort it out!

Always start simple. Did you go into the sound settings and make certain the Intel audio was set as the output? Sometimes windows updates will swap it to the mainboard audio as the default.

I am confused. You installed a beta OS/update on your PC?

The plot thickens, Punisher! I can't be sure if this arose from first installing Windows 11, or getting the 25H2 update. Could be the former! It worked properly in Windows 10. Windows somehow "imagined" that I have a "Remote Audio Device" -- as with Blue-tooth, but there's no bluetooth on this motherboard, nor USB "bluetooth" dongle. I removed the device. But there is also an Intel [display] Audio device in the usual list of sound and game controllers -- the usual sound node in DM.

Rebooting reveals -- in addition to the RealTek audio that I'm not using -- a "Sony Bravia Display Audio". Now it appears in the sound dialogs as merely "stereo" left and right, but hitting the "Test" button on the screen gives successful left and right response.

There is information on the web about configuring "Windows 11" HDMI output for Sony Bravia as 5.1. The Bravia uses the eARC connection to my HD Receiver -- also Sony. There is a way to fix this, and now I can say it's only "half-broken".

"Sony Bravia Display Audio". That should be the one you want. Mine says HISENSE (AMD HIGH DEFINTION AUDIO DEVICE) as that's the TV and video card I am on at the moment.

Under the advanced tab in sound settings click on more sound settings. There you can choose the audio device and configure it for 5.1.

It was the "Windows Insider Program" "DEV" channel 25H2 rollout. After reading up on web-search results, the 25H2 version does not seem intrinsically responsible for this outcome. It is the way that Windows 11 made sense of devices and drivers at the get-go. But there is a way to fix it.

After first installing Windows 11 about two days ago, I didn't think to try playing a movie from my ISO jukebox.

It's just that the Windows 11 default presentation of devices and configurations doesn't so easily reveal what we're used to. But right now, I have it producing sound in stereo, and there are settings within the Bravia itself as well as the Win 11 PC which enable 5.1 surround.

You have to ask why they couldn't just leave well enough alone with the logic and structure of Windows 7. Really. I mean it.

At the moment, in the presentation of the "Sony Bravia Audio Device", there is also an indication of "Intel" sound controller. That may not be the precise wording, but it only makes sense.

So far, I'm getting stereo, and I just have to sort it out for 5.1 Surround.

Can't let sensible things developed by their predecessors be left alone because then it brings into question what the new hires are supposed to be doing if everything was already working fine. Gotta justify their high salaries. I have my dumb IT guy running around and upgrading people to Win11 and logging them onto a domain server yet he hasn't got a lick of sense what the benefits of doing that are. So far, three people have had to login to their PCs by disconnecting the network cable so it doesn't try to login to the domain. This is progress?

The inclination of home networkers running Windows Server was to circumvent having a Domain server, running the Windows server OS in a "Workgroup" configuration. I KNOW that the Domain Server concept was imposed in a business environment. But I can't wrap my brain around removing the ethernet cable. Then -- no network or resources from the network.

I just discovered something. When the Bravia is switched to a streaming source or subscription, this "Remote audio" mystery reappears when accessing the (server/media) system via Desktop Remote. But then , that all makes sense. I have to sort all this out. Trying to configure audio through RD is a disaster for what I'd achieved earlier this evening. More tomorrow, then.

Oh, they connect the cable once it is logged in.

The scummy/scammy IT administrator has almost zero clue about these things. He is getting an outsourced vendor to do this stuff and claiming to be the IT heartbeat of the organization.

The only thing preventing me from sending off a scathing email to everyone feigning ignorance is that either they will find some way to attack me or even if the idiot's ousting is successful, they will hire an even bigger idiot. The management of some companies (like Intel) is very good at hiring people who excel in doing subpar jobs but pretending and showing off like they built a NASA rover.
