Hdmi sound not working

Hi Peter,

One possible reason why the HDMI sound does not work is due to the conflicts with the playback settings. For us to help you make the HDMI sound to work, we suggest that you answer the following questions for further research:

• Have you made any recent changes to your computer?
• What is the current build and version of your Windows 10?
• Have you tried to download and install the most updated sound and display driver of your computer?

Meanwhile, we suggest that you perform the steps on this
article as our initial troubleshooting and see if there will be any changes on the HDMI sound.

We'll be waiting for your response.

 

Muffled Sound

Hello,

When I open more than one app the sound becomes muffled; for example, I'm listening to music and it sounds normal, but if I open a videogame the sound becomes muffled.

The audio driver is Conexant SmartAudioHD

Also, my headphones don't appear in the sound devices.

Does anyone know any solution?

 

Muffled Sound

1.- It doesn't solve it.

2.- If I pause the music the sound in the game continues muffled.

3.- I've updated the audio driver through the device manager but it continues the same.

4.- Will do.

Also, I should add that if I turn up the song's volume it seems to not muffle the sound from both the videogame and the music as much, but it's still there.
