[SOLVED] Sound Card/HDMI/Receiver - is this possible?

[LucasLND]

Hi, could you please let me know if this is possible:

I have a graphic card GeForce RTX 2070 SUPER connected to my receiver via hdmi. I also have a sound card Sound Blaster AE-7.
My problem is that I can’t send sound via hdmi from sound blaster. Sound is coming from Nvidia High Definition Audio. Is there any chance that sound will go from sound card via hdmi to my receiver?

You could use the TOSLINK Optical-out port with an optical cable and connected your system to the receiver.
Also you could get a TOSLINK Optical to HDMI adapter and connected it to the receiver via HDMI cable.

I am using the 1st option to connected my Sound Blaster Audigy to a Denon receiver.

There is no standard way for the sound from an audio card to be passed though the mobo to the video card. The only option MIGHT be if your video card has an audio INPUT jack you could feed via cable from the audio card. But I have never seen such an animal. THAT is why all video cards now come with their own audio chip on the video card - just so audio can be sent out of the HDMI port of the video card.

IF you prefer to use an audio card to generate the sound, and then pass it to an external receiver, you need to use a cable from the audio card directly to the receiver. This MAY provide you with an advantage. Most audio signals from a video card on HDMI are 2-channel stereo. On the other hand, most audio cards can generate more channels, like 5.1 or 7.1 Surround Sound. Of course, to use that you need to get those signals to the receiver, and the receiver has to be able to deal with multi-channel audio, and you need the speakers for it, too. But if you have all that, the best options for getting the multi-channel audio to the receiver are the analog or optical outputs of the audio card to a corresponding input on the receiver.

If you opt to make such a connection, then you have to tell Windows to use the audio card as the default sound output device, and not use the chip on the video card. This is set by going through Control Panel ... Sounds etc. But then, of course, there will be NO sound signal carried by the HDMI cable from the video card. All this is because Windows can only use ONE device to output sound at a time.

Hello Gents, thank you both for your response. Now I need to find out which connection to use for 5.1 with my denon receiver avr 3313. Should I use the TOSLINK Optical-out or analog Mini Jack to RCA?

Definitely the optical TOSLINK for 5.1 audio
