Send sound via HDMI cable to a Yamaha RX-A880 AVR

[DCost15]

Hi everybody !

I have a problem with sending the sound to a Yamaha AVR. I use Windows 10 and in the sound settings in "Choose Your Output Device" section, the HDMI option does not appear. In fact there is only one option, "Remote Sound". I also installed the latest version of BIOS, no result. I would like to send multi-channel sound to AVR as well as Hi-Res DSD / DSF audio material.

Any advice will be highly appreciated.

In order for the Intel HD Audio driver to be activated, the Intel HD Graphics driver must see a TV/Monitor device that also exposes an audio output capability. In cases such as this, Receivers typically pass through the graphics side of the TV/Monitor but exposes its own audio capabilities - getting you 5.1/5.2/7.1/7.2 audio (what the receiver is currently supporting) rather than the (typically stereo) capabilities of the TV/Monitor itself. The question is whether the Receiver is currently connected to and exposing a TV/Monitor. Is this the case?

Hi, Scott! Thanks for your suggestions but in fact, my case are total different. I use a Samsung TD270 as monitor which haven't any audio output possibilities. Not even S/PDIF. It have only 2 HDMI inputs, no one of them ARC type. I tried to use a 10' tablet as wireless remote screen to play music from NUC. It was worst, no audio outputs was visible in addition of 'Remote Sound'. So, in remote way of Win 10, no access to settings ! Only when the mini pc is connected to Samsung monitor (via HDMI) the digital outputs are highlighted but inactive (they are grey and with a down showing arrow). I'm a little bit confused maybe I must use as monitor a tv with HDMI ARC capabilities? By the way, I have sound in Samsung's loudspeakers.

But nothing in Yamaha RX-A880 avr.

Further I've to dig deeper...

If your TV/Monitor has speakers, then it has an audio output capability. This has nothing to do with any pass-through capability it might (also) offer. The Receiver, being ahead of the TV/Monitor in the chain, should override this and report its capabilities instead. For example, instead of reporting that the TV/Monitor supports a 1080p graphics output capability and a Stereo (2.0) audio output capability, the Receiver would report that it supports a 1080p graphics output capability and a 5.1/5.2/7.1/7.2 (whichever it can handle) audio output capability. It would then pass the graphics signal through to the TV/Monitor and process the audio signal itself.

If the information that the PC is receiving over the HDMI connection does not indicate that an audio output capability is present, then the Graphics Driver will not expose the Audio driver. Since this is what you are seeing, this means that there is something going wrong at the Receiver or the Graphics Driver is somehow borked. Could this be the absence of ARC support? I don't think so; there should be an ARC connection between the Receiver and the PC.

I do not understand your tablet example. Do you mean one that remotely connects with the PC via Networking or Bluetooth?

Do you have the RealTek audio driver installed?

Hi, Scott.

Because english is not my native language. Fortunately, I have a good friend who works in IT who has installed a vnc server on NUC and a vnc-viewer app on the tablet.

I set vnc to start at the same time with win 10, set a static IP for the connection to NUC. Now I just start the mini-pc, start the application on the tablet and go directly to windows.

Anyway, thank you for the effort you have shown to help me.
