HDMI force carry 5.1 Sound
So I recently bought an external decoder that splits up my HDMI-Signal comming from my RTX 2070 Super into HDMI image signal and the corresponding audio signal split up into 5.1 Sourround Sound.

https://www.amazon.de/Speaka-HDMI-AUDIO-EXTRACTOR-AUSGANG/dp/B00MOKEEAQ/ref=sr_1_2?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=speaka+professional+hdmi+5.1&qid=1586711991&sr=8-2

This device in particular...

Now my problem is that Windows recognizes my computer monitor as my "Output"-device which only supports 2.0 sound. So I cannot make any use of my external home-theater. The only thing I have to do is to trick Windows into forcing 5.1 audio output over my HDMI connection. Any ideas on how to do so?

The two outputs coming from the current HDMI source are working fine with that audio extractor and I can transmit them over to my home-theater. So the decoder is working fine

That's exactly why I tried the extractor because I thought this would be recognized as the receiving device and therefore enforces 5.1...unforturnately it was not the case...


Anyways @all this thread is declared closed because I already refunded the extractor and ordered an up to date receiver
I hope it fixed with a new receiver, and good luck.

its the limitation of that extractor
its only 5.1 (6 channels)
dts es is matrxed surrounds channels (pulling auido from surrounds to make surround backs)
dts hd is lower quality all around to make room for the 2 extra channels

this is a 7.1 analog extractor, upto 5.1 to optical

Well that ultimatively does not answer the question really...
https://www.soundandvision.com/images/styles/600_wide/public/072114_Poll_SurroundSetup.jpg
Here is a comparation of a 5.1 and a 7.1 setup. Left is 5.1 and right is 7.1. My current setup corresponds to the left image which should be... well which IS supported by my receiver as well as it should be supported by the extractor I've bought.

I only have 6 channels here...
Frontleft and -right (2 channels)
Rearleft and -right (2 channels)
Subwoofer and Center (each being represented by one channel)
The only difference to your given device is that I have 2 additional channels that are designed for two additional sourround sound speakers

Your given device is completely useless to me since my receiver only supports up to 5.1 output which is infact true given the manual I've read before the setup.

The only thing I need right now is what I've been saying in my initial post...

Because the only problem here is Windows still favouring my monitor as my output device which only supports 2.0 sound (given a right and a left speaker) and therefore deactivates / hides the options for 5.1 and 7.1. On Linux this works perfectly fine since Linux lets the decision up to ME if I want to do a Mono, 2.0, 4.0, 5.1 or 7.1 output.

What I have done. Use the DP cable to the monitor. Or one of the HDMI if no DP. Then a second HDMI cable to the receiver. Set up dual monitors in Windows and/or video card driver Extend or maybe duplicate the display. It helps to have a TV hooked up to the receiver while doing this. Make the monitor your primary display. You should now see two audio devices in Windows speaker setup - advanced setup. Make the receiver your primary sound output. You can disconnect the TV after all is working.

Thats the Problem... My current receiver is old... It does not have HDMI

I made things short now and refunded the extractor. Tomorrow I will buy a new receiver and thats it then I guess

Does your receiver allow multiple line inputs. Like an input plug for L R Center and surround L R?

Then you could connect to the MB sound outputs.

If it has an optical input, you can get 5.1 surround sound. Just run an optical cable from the MB.

This is assuming the MB has sound ability. I think that the sound ability on the video card will be better than the MB chip. But I have no proof of that.

Yes it does but the Main Intention here Was basically having my sourround headset and my home theater connected at once and just switch by Windows Sound...

Anyways I ordered a Pioneer receiver now that ist more up to date and it supports HDMI in and outpu with HDCP2.2 so I guess I am fine now :D

Use DP for all of your actual video monitors. Use the hdmi output to surround receiver for your audio. However the hdmi has to be an enabled active display in the OS for it to carry the audio. But this is only way to get the full 5.1 audio without it being dumbed down to Stereo due to using an actual hdmi video monitor

Well the only problem here is the extractor is unable to track the real audio receiver so it carries the handshake between monito and computer which results in a stereo signal. When I hook up my computer to my ordered receiver it should track this as audio device and the image signal can just be pushed through to the HDMI outlet of the receiver so I am fine.

I only wanted a cheap solution... but I guess I won't work my way around buying a more modern HIFI setup entirely

in windows audio control panel, disable the monitor speakers and other devices you do not want it to use

It still forces me into stereo mode. It is not using these speakers it. correctly splits the Audio from the Image and tunnels it to the receiver but the problem is that physically the HDMI handshake takes place between monitor and computer which is recognized as "Stereo Device". So unless I do not override screen drivers or anything I can't do anything.

I literally tried every Windows setting you could name here by now...

is th switch on the extractor set to 5.1?

What is a sort of game or media you are try to play in 5.1 surround mode? Also, what about the switch?

I made my own theater room by the way.

@_I_, I must make my point. DTS HD doesn't transmit to analog out, so no DTS or Dolby is going out from analog outputs. First, GPU's HDMI tranmitted a DTS or Dolby to the receiver, then it uses DAC to make analog outputted a sound. DTS HD and Dolby TrueHD are high-quality audio that can only be done by HDMI.

@Jamebonds

It does not matter what type Media... I tried Youtube and Disney+ as well as local stored movies as well as games with ingame setting to sourround Sound. Eitherway it refused to transmit in sourround sound

Again, get rid of any Display connected to an HDMI. Connect hdmi cable from gpu to audio receiver then this shouldn't be an issue. Many users do their surround sound this way. All monitors should be using DP if you wish to do it this way though, since most gpu nowa days only have 1x hdmi but have 3x dp
