Help - how to duplicate/mirror audio in Win 10?

[breeminator]

I have the following setup:

1. Gaming PC connected to a freesync monitor via displayport that runs at 165hz
2. Recording PC that has an Elgato HD60. This works fine with a PS4, for example, where I connect the PS4 to the Elgato, then play using the Elgato output, which has both audio and video at 60hz.

The problem comes when I want to use the Elgato to record the PC video+audio. I have Win 10 set up to mirror the displayport output to HDMI, and this works absolutely fine for the video, I can game at 165hz on the gaming PC, and the Elgato records a 60hz version.

But, unbelievably, the audio isn't mirrored along with the video. I have searched for solutions to this - I've tried the stereo mix solution, audio router, chevolume, absolutely nothing is duplicating the audio to the Elgato.

How can this be so hard?!!!!!!!!

Are you outputting the audio to the HDMI source? does your GPU allow for this?
try this? https://answers.microsoft.com/en-us...ndows-10/b284def2-d684-4f1f-87a0-f562f556aedd

ANother solution could be to record the audio separately from the Elgato and mixing it in later using whatever video editing software.

That's the "stereo mix" solution - I tried it but it didn't work for me. Also, people say it causes a delay, which would put the audio out of sync in my recording.

I've since discovered a totally different solution which is to not use the Elgato at all, and use NDI to send both video and audio to the capture PC:

The only obstacle to this is that I currently have my gaming PC on a different network to the capture PC, but I'll probably change that to give NDI a try.

Voicemeeter can duplicate outputs, along with a whole load of other useful things. (I use Voicemeeter Banana to downmix and EQ a second output for driving bass-shakers). I don't notice any delays, anyway, it's free to try
