You may want to open the control panel (as Administrator) and enable Volume Control for convenience, but the other default settings seem fine. Install Virtual Audio Cable - it comes with one virtual cable by default.

My understanding is that you have a program that is playing audio, and you want that audio to simultaneously be played out two USB audio devices. I was finally able to do it with Virtual Audio cable. OH MAN this was so hard to find an answer to. Select second TV display as the output and press startĪudio should now hear from both TV displays and also from the PC speaker/output.Run C:\Program Files (x86)\Virtual Audio Pipeline\Audio_Repeater.exe.Set Realtek Audio as default playback source Install and copy msvcr100.dll to "C:\Program Files (x86)\Virtual Audio Pipeline".Go to folder: "C:\Program Files (x86)\Virtual Audio Pipeline" and right click on vrtaupipe.inf and select install (it will warn about unsigned driver).I had to reboot on mode that allows to install unsigned drivers:.Unfortunately Windows 10/Realtek Stereo Mix "repeater" only works with PC audio output or with the PC speaker not with two different HDMI Displays.

What I wanted is that the audio will come out from both displays.

You can even hear the audio source from three different audio outputs. I finally found solution for this that works and it's free (open source).
