HDMI to connection to TV - Only one speaker working

I assume the TV stereo works when under its own control.

This sounds to me like it might be a cable / connector fault.
At the very least, I think you should swap the cable with another to prove or eliminate that possibility.

Best of luck,
Denis

Welcome to TenForums.

It's really worth making time to browse through the Tutorial index - there's a shortcut to it at the top of every page.

- At the foot of the Tutorial index is a shortcut to download it as a spreadsheet.
- I download a new copy each month.
- By downloading it as a spreadsheet I can benefit from Excel's excellent filtering capabilities when I search for topics of interest.

- Tutorials are also listed by category at Tutorials - there's also a shortcut to that at the top of every page.
- Both tutorial lists are searchable.
- You can also search for TenForumsTutorials in many general search engines, such as Google, by adding site:tenforums.com/tutorials after your search term. For example,
taskbar toolbars site:tenforums.com/tutorials

You can search TenForums using the search box in the top-right corner of all TenForums webpages or using Advanced Search - TenForums
- You can also search TenForums threads in many general search engines, such as Google, by adding site:tenforums.com after your search term. For example,
Search for drivers by HardwareID site:tenforums.com
- [This is what the search box in the top-right corner of TenForums webpages does automatically]

That's a pity.

When I had the problem with my output to TV, before replacing the cable I had bought a USB-C to HDMI adapter but that had proved to be a waste of time & money because not all computers can provide an HDMI output through the USB-C connection. I never did find out what specs I should have checked first to find out if it could do this.

Perhaps your computer maker has a user forum where you could ask if anybody else has had the same problem?

I do have one stupid idea though. make a new Windows 10 system image, restore a Windows 7 system image [assuming you have one], make notes of the sound card driver & any 'Display audio' drivers in Device manager, backup your drivers, search the backup's inf files until you can positively identify the relevant driver[s] then restore your Windows 10 image and restore the old driver[s].

Best of luck,
Denis

"get"? I meant one that you had made.

I forgot to include this link. I didn't know about it when I had Windows 7 but somebody else told me in another thread here that they were able to use the same commands successfully in Windows 7.
Dism itself definitely existed in Windows 7 but my own old notes do not mention exporting drivers.

@rooscoota
Rob,
I think you used this Dism command to backup drivers in Windows 7. Do you have any advice for Knopfler?
