I bought an Evga NU and I have a serious problem. I have it connected by Toslink to a Yamaha RX-V673 5.1 receiver and it does not play either DTS or Dolby Digital. In sound options the control panel of windows 10 tells me that it can not play DTS or Dolby Digital samples.
Before with the integrated sound of my Aorus Z390 Master and with a Creative AE-5 all ok both DTS and Dolby Digital.
I have the integrated sound disabled in the bios and I have the NU Audio connected directly to my Corsair RM 1000 with a cable like that of the other SATA peripherals.
I have come to format my PC and reinstall everything and the issue has not been fixed. The drivers of the card I have installed 20 times and nothing, I have downloaded to 24bits and 44100 and 44800 and nothing. I do not know what else to do.
EVGA offers me a card replacement but for me and my experience of many years, it is a driver problem and with a card replacement it is not going to be solved.
Does it happen to someone the same?
Could you fix it?
Any ideas?
sorry for my bad English

This is a driver issue, not a card problem.  Seems like there's an issue with 5.1 compressed audio at the moment, and our team is working resolve it.

THANK YOU
I'm canceling the RMA and I'm waiting for a new driver.
Say nothing more than I'm a bit annoyed with EVGA since at my age and although I dominate the subject quite a lot, you always think that you do something wrong and waste precious time, even going to format the pc.
In all the information it says that it works 5.1 and it is understood that it is Dolby Digital and DTS (even the integrated audio of any motherboard of middle class does it from the first day) and it would have to be warned that it will work with some next drivers. It would have saved me days of tests, installing and uninstalling drivers a lot of times or if I had known it I would have waited for this to work since I see many movies that use these audio systems.
In this sense serious failure of EVGA and for me improper of a mark of its prestige.

But the problem is that despite being connected by optical cable the Yamaha does not receive the order to decode DTS or Dolby Digital so I understand it is a problem of the drivers of the EVGA NU Audio

I hope you realize the NU Audio is a Stereo only sound card with optical out (passthrough). It won't do anything to improve the digital audio signal being sent through the optical cable to your Yamaha RX-V673 5.1 receiver. The receiver does all the audio processing when you use optical cable to it.
