Windows 10: Problem outputting 5.1 surround sound from PC via HDMI

I am running an HDMI cable from an HP PC to a 5.1 home theater system. Specifically the HDMI goes from the PC to a TV, then another HDMI goes from the TV into the 5.1 receiver. The non-PC portion of the setup works fine - the TV outputs 5.1 sound just fine when it's getting input from an X-Box, but not when it's getting input from the PC.


Instead, Windows is only outputting stereo sound.


Several posts on this forum and YouTube videos suggest trying to fix this problem by reinstalling RealTek HD Audio Manager. That didn't do it. The RealTek HD Audio Manager app only gives "Stereo" for a Speaker Configuration option. Going into the Playback tab of the Sound control panel, I am able to see Stereo and a "Dolby Atmos for home theater" option, but selecting the latter does not actually result in any surround sound - it's still stereo.


Thanks for any assistance.

Hello, Im trying to output my PC sound to my dual monitor setup (HP VH240a x2)

I've tried enabling the stereo mixer in windows and replaying to the second monitor and even used a direct audio jack instead but nothing.

Also, I tried NVIDIA's Control Panel and enabled surround but it doesnt work

5.1 surround sound issue in Windows 10

Hi,

Thank you for your response.

I suggest you to follow the steps below and check if it helps.

If you’re connecting an optical cable the settings would be changed so try the following steps

Two options:

1. Use the optical S/PDIF output of your motherboard.

2. Use the HDMI output of your GPU. (This is what I'd recommend if you're using a HDMI display).

I suggest you to follow the steps below and check if it helps.

• 
  Go to control panel.
  
• 
  Select sound.
  
• 
  Click on playback devices.
  

For option 1- connect the cable and set the 'Realtek digital output' as default device.

• 
  Then right click on it.
  
• 
  Go to properties.
  
• 
  At the rightmost tab select DTS or Dolby Digital or 5.1.
  

For option 2-connect the HDMI cable through the receiver and set the 'Nvidia HDMI Output' as your default device. Then click 'Configure' and select 5.1 and check if it helps.

If the issue persist then, I suggest you to connect the speakers directly and check in the realtek audio manager if he gets the 5.1 option or not using the SPDIF\output.

Keep us posted on this issue so that we can assist you better.
