Aorus Xtreme X399 Digital Audio

[Guggsy]

Hi Folks please can someone help regarding digital audio output on my MB. The Audio device is Realtek hd audio, plugged into my A/V receiver via optical toslink lead. I have a 7.1 speaker setup. My receiver detects a digital audio signal, as I have tested movies. But if I try and play RE2 remake. I just get stereo output. No Dolby digital surround or Dolby Atmos.

But however if I play audio through my nvidia gpu everything works as it should. GPU is also connected to A/V receiver via HDMI. RE2 remake works in dolby atmos and digital.

I have DTS and Dolby Digital checked in supported formats for reaktek HD audio.

Dolby Access setup only is for output via HDMI in order to get dolby Atmos which My GPU has.

Has anyone had a similar problem and what steps did you take to fix it. I have a creative labs ZxR sound card which I used first but it only supports 5.1 audio and does not support Dolby Atmos. Just dolby digital live or DTS.

I have downloaded dolby digital plus which is NOT officially signed. I have not installed it. Plus I still don't think it will give me what I am looking for. I would have thought the sound output would have been just as good as my GPU sound if not better.

Please Advise

Thanks James for your reply. It just seems really weird to me that there is no sound card that has hdmi. I cannot believe that, I can get better sound out of my GPU than I can out of my MB and dedicated sound card combined. So even if I brought a soundcard which supports 7.1 speaker setup, unless it has HDMI, I am not going to get Dolby Atmos.
