  • I use Windows 7
  • I have an ASUS mobo w/realtek built in audio w/front & rear jacks.
  • I have a Logitech USB headset w/microphone.
  • I have ?20? sets of headphones.
  • The Realtek HD Audio manager doesn't even see the USB headset, it has a separate driver.

The Problem:

I need to use the headset/mic and regular headphones to play the same audio at the same time, ie, one kid is playing an online game and the other wants to be able to listen without waking up their extraordinarily grumpy, late night working dad(me). No, I don't want to just buy a line splitter or something along those lines. Yes, I know it would work, but there are specific reasons I can't do that. I already know that Microsoft is stupid. I know that Windows 7 Doesn't support this on its own. I know iOS, Linux and that OS the kid down the street threw together for a science fair are all better than Windows. But I have Windows, not one of those.

My Question:

Is there a way, any way, to get the same audio stream through both devices? Is there software outside of windows that can be used? Are there some settings I can take advantage of since both are separate devices?

One way of accomplish this is to play the same audio stream through two mediums (analog & HDMI). See how to do that here:, answer reproduced below:

  1. Open Sound panel
  2. Select Speakers as the default playback device
  3. Go to the "Recording" tab
  4. Right click and enable "Show Disabled Devices"
  5. A recording device called "Wave Out Mix", "Mono Mix" or "Stereo Mix" (this was my case) should appear
  6. Right click on the new device and click "Enable"
  7. Right click on the new device and click "Set as Default Device"
  8. Double click on the new device to open the Properties window
  9. Go to the "Listen" tab
  10. Click on the "Listen to this device" checkbox
  11. Select your HDMI device from the "Playback through this device" list

Then you can just connect the headset(s) to both the HDMI device (TV or monitor) and the analog (PC or Speakers) output.

Doesn't work for me on Win8.1 – Iszi Oct 24 '14 at 21:07
Fixed it. Needed to put the volume of my HDMI device to max. The volume for both devices is then, effectively, controlled by adjusting the Speaker device volume. – Iszi Oct 24 '14 at 21:14
Ok. Got it working on my Win8.1 laptop, but I have another Win7 system that this doesn't seem to work for - no "Wave Out"/"Mono"/"Stereo" device shows even when showing disabled devices. – Iszi Oct 24 '14 at 21:44

Jack can stream audio to multiple devices.

JACK is system for handling real-time, low latency audio. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications).

Mustn't the sound-producing app be a Jack client? Or does Jack provide a shim or driver that allows normal Widows audio programs to route through Jack? – Joe Koberg Jan 25 '14 at 17:47

You can stereo mix, but there is a slight delay in the 2 devices. You can get say an HDMI audio extractor then you have one device with dual audio (from the extractor and still the HDMI) if you don't have a sound card or room for a soundcard.

My solution: voicemeeter. It does have a small overhead of up to 5% CPU usage, but the output is not delayed on any hardware device. It basically creates a virtual input that takes in the audio you would normally hear and then sends it to up to two hardware output devices.

To manage several microphones and speakers devices, we recommend Voicemeeter Banana, the virtual audio mixer for Windows specially made to route and mix several physical or virtual I/O. Voicemeeter interconnections
