I have 2 monitors both plugged in via DisplayPort. Both monitors also have HDMI inputs, but I am only using the DisplayPort inputs. They are plugged into the same discrete graphics card.
My computer has an ASUS motherboard with a good sound card built-in.
I never liked that I can only choose one or the other monitor to output sound to. I would like sound to be output from both monitors at the same time, though I do not want a delay between the two.
How can I output sound to both monitors at the same time in Windows 7?

Try to use Audio-Router's "Duplicate" function:
Windows apparently does not support this, but your sound card might.
Since, I have an asus mb I suspect that you have a realtek hd audio sound card, if not I suspect the process is similar. First, you have to get the audio driver from the realtek site if you don't already have, because the windows divers won't support it. Then you have to go to your audio devices and show disabled devices and enable "stereo mix". Go into properties and go to the listen tab and select listen to device which will "listen" for the sound in your main device. Underneath that button their is a menu "playback through this device" and select the second device i.e. your second monitor.
A more low tech solution might just be to buy a audio jack splitter and plug audio jacks from the splitter into both screens.
hope this helps!
3You can download Voicemeeter and VB-audio virtual cable. Open up voicemeeter and set your hardware out to both monitors, then set your virtual input to VB-Audio. After that set your default playback device to VB-Audio
It should look like this
I was looking for something like this and come across the solution accidentally.
