SOLUTION: Duplication doesn't work

[AudioDuplication]

Hey Guys, I am using Windows 11 and duplication stopped working for me.

So I found another way of duplicating the audio. I have seen many people suggest you use VB-Cable and other bloated, complicated and ugly solutions. Bloated because they install all kinds of drivers and virtual audio devices you don't need.

How do I do this? I will explain in a few steps:

1. Installation:

a. Download and install OBS https://obsproject.com/
b. Download and install the OBS plugin "Win-caputure-Audio" https://github.com/bozbez/win-capture-audio

2. Setup

a) Choosing where to duplicate the audio to.
Open OBS, open the settings, click the audio tab, find the "advanced" section.
Here, set "Monitoring device" to THE DEVICE YOU WISH TO DUPLICATE TO.
save and close the settings.

b) Choosing which process(es) to duplicate the audio from.
On the OBS main screen, under the "Sources" section, click the + icon, choose "application audio output capture" and press OK.
A window will open...

• Either press the + icon and enter the .exe name of the processes you wish to duplicate the audio of.
• Or, choose a running program from the list under "Add from currently active sessions" and CLICK ADD EXECUTABLE(!).
  save and close these settings.
  If you wish to re open this window later to edit the process list, just double click the source you added.

c) Enable the duplication (only need to do this once)
under the "Audio Mixer" section, on the main OBS screen...
click on the gear icon under the "Application Audio Output Capture", and choose "Advanced audio settings".
A window will open, under the "Audio monitoring" section, set it to "Monitoring Only".

I made a 1 minute video of step 2:

Many many thanks to @bozbez for making the OBS plugin, and ofcourse to the OBS-Project

You can also check this video for a more detailed tutorial of how the OBS plugin works, if you are curious.

Note that this video alone will not tell you how to use it like Audio Router would, you need my own tutorial for that. But it may help you get more out of the plugin.

Hello
This "OBS solution" is not as good as audio routeur. It takes all the memory and the PC is even not able to run netflix app properly. We need a solution patch from audio routeur ...

The monitoring device has a bit of lag, but hey, we solved an impossible problem that only the bright minds of android and Apple devs could solve

Thanks, that's what I just needed.
