How to output audio to multiple devices in Windows 11?

Completely agree MS needs to fix this. People don't seem to understand that if you are using a USB gaming headset but want to also stream your audio from a game to a hardware recording device. You cant send the audio stream easily. I don't want my gaming machine running a bunch of extra streaming software. You have to use special software like voicemeter potato and it is a pain.

Complete fail for an answer to the issue. Very retro-as in 1970s approach. My phones (both android and iOS) even have this function. My use case is not one where a dual headset splitter would even work. a 3.5 cable or even USB would not solve it. You are missing the point. I need the output to be mirrored to multiple sources. This means I could choose the outputs - for this specific case, BOTH the Creative and the Audeze...or whatever my needs are. It is now an industry standard. Windows is lagging in this regard. Period. Audio mirroring as a feature is the norm across many platforms. Windows needs to catch up.

You could just get two 3.5mm headsets and y cable. That's what people used to do. You may even be able to find a way to y USB for all I know. External 3.5mm speakers can be y'd as well.

Windows 99.9% isn't likely to go to add multi device output so you should find an alternative way if you want it that bad.

Otherwise just buy a $20 usb speaker and listen to it at the same time :)

No one wants to use two sound cards, but there should be an option under "choose where to play sound" that lists your main speakers, SPDIF, bluetooth speakers, et cetera that let's you chose multiple outs at once. Where is this function? It's vital. Apple has this for their products. It's a glaring deficiency in Windows.

This use case comes up a lot for me when gaming. I use headphones and want to play with my son or friend, so mirroring audio to another headset would be helpful. This should be easy for the user to do, with an option to select multiple output devices.
