Hello,

Everything was working great with Dolby Atmos,

but suddenly experienced some black screens every few minutes.

So I tried to re-install the graphics drivers, which solved my black screen issue.

But now all of the sudden don't have Dolby Atmos sound anymore, only stereo sound.

 

I've tried every solution I could find on the net, updating the display drivers, updating the hdmi audio display driver, used the troubleshooting wizard,etc....

 

Nothing solved the issue.

The weird thing however is that when connecting it to another HDMI (HDMI DVI) input,

it works, I can enable Dolby Atmos with no problem.

But after that when I try the other HDMI (HDMI ARC)input again,

I can't enable Dolby Atmos on that.

 

The simplest solution is off course to use the input that works,

but I like to know why the other HDMI input doesn't work anymore.

 

Maybe there is a way to make the pc forget/reset what it knows about the HDMI input and then it maybe works again ?

 

Thanks in advance for any help.

 

Greetings,

Soxbrother
