Windows 10: Why won't Windows 11 output 7.1 surround sound to AV Receiver?

Recently purchased a Surface Laptop Studio and can't get it to output any surround sound to my AV Receiver. I've tried connecting using the USB-C Travel Hub, USB-C to HDMI Adapter, even the Surface Dock 2, all to no avail. I've confirmed that the Surface's Sound Settings are configured correctly Settings, System, Sound, Advanced, More sound settings, Playback, Configure, Properties. My receiver outputs 7.1 surround just fine with Windows 10 devices, XBox, etc. The receiver I am using is a Sony STR-DH770, and the HDMI format is set to Enhanced.

Send sound to AV receiver but have only 1 monitor in Windows

I have a very complicated problem that I hope you can help me with.

I have the following setup:

• PC with:
  
  • DVI out to primary monitor
    
  • HDMI out to AV-receiver, which then goes to TV and 5.1 sound system
    

I want my sound to play on the AV-receiver. To do this, I have to "Extend" or "Duplicate" my desktop to the AV-receiver (i.e. the TV). If I do not do this, the sound also doesn't go to the AV-receiver.
However:

• Extending desktop is a problem, because my TV is not always on, and windows will still randomly move to this 2nd monitor (I can get them back with Windows + Shift + L_ARROW but this is not ideal...)
  
• Duplicating desktop is a problem, because my TV is 16:9 and my PC monitor is 21:9
  

So what I need is a solution that allows me to still send the sound through HDMI to my AV-receiver, but have only 1 desktop on my monitor (not on my TV). Obviously, the option to extend to my TV should still be available, should I want to watch a movie on my TV.

I hope my question is clear, and I hope someone knows a solution. I don't mind a solution that uses 3rd party software.

 

av receiver Bluetooth Connection on Windows 11

Hi Claudeir,

I have narrowed it down to an issue with the Realtek Audio driver as it is the same issue on Windows 10 or Windows 11. I did a fresh install of Windows 10 and Windows 11 and while the Realtek driver is not installed I'm able to connect to my AV Receiver and play audio but as soon as Windows installs the Realtek driver I'm unable to output sound to the Bluetooth AV receiver. The issue is only with the Bluetooth AV Receiver. I'm able to connect to a Bluetooth speaker without any issue. I have emailed Lenovo support as well as I have a Lenovo X1 Carbon Gen 8 and hopefully they can resolve the issue.

 

Windows 10 audio stutters regardless of driver or output used, more noticeable on the toslink and surround sound.

• Its a desktop, i listed the components in the original post.
