Wave Link can mix up to eight inputs together. These inputs can be a variety of software sources like games, voice chat, music, web browser and hardware sources like other microphones.
Wave Link relies on the Windows Audio Routing capabilities to tell programs to output to a specific Wave Link input, thus giving total control. Unfortunately, not all programs strictly adhere to the Windows Audio Routing system and will ignore the settings.
This guide will go over how to use a program called EarTrumpet to force programs to output to a specific Wave Link channel.
1) Install EarTrumpet from the Windows store - https://www.microsoft.com/en-us/p/eartrumpet/9nblggh516xp
2) Once installed, a second speaker icon will be visible in the Windows task tray
One speaker icon is the Windows sound settings, the other is EarTrumpet
3) Open the program that will be routed by EarTrumpet to a specific Wave Link Output. In this guide as an example we'll use Overwatch
4) Once the program is open, left-click on the EarTrumpet icon to see the list of programs
5) Right click on the program which will be sent to a different audio device
6) Click on the left-right arrow settings icon. Now select the output through which the program will play sound.
In this example we want Overwatch to play through Wave Link Game. so we select "Wave Link Game (Elgato Wave:1)"
7) Sound from the program will now play through the selected Wave Link channel.
Note: If the sound is not playing, please close and re-open the application
If no sound can be heard, make sure the Wave Link channel has been added to Wave Link.
In our example, if Overwatch is playing through Wave Link Game but Wave Link Game is not added in Wave Link, there will be no game sound
Programs which are routed to a different audio output will not appear in the main list.
To view all audio devices and which programs are playing through which device:
1) Left click on the EarTrumpet icon
2) At the top, click on the audio device with the up arrow
3) A new sidebar menu will open displaying all audio output devices and the programs playing sound through that device.
4) To edit where a program plays audio, right click on the program
5) Select the left-right arrow and then select the output device that the program will play audio through
