Hi,

I’m using windows 10 64bit with Nvidia 1080 GPU.

I can not get DTS-HD to work, or 7.1 Audio option in the windows playback devices.

When I connect directly with HDMI, I get 7.1 without a problem and everything works fine.
When using the 1070, through the DP, I only get a 2 speakers stereo option, and even the testing of the audio does not produce any sounds, it just does not work.

When playing some test files, I can get Dolby Digital and DTS to work, but as I said not DTS-HD.

Is there a way to fix this?

Thank you.
