If Wave Link is showing a "Double audio detected" warning, you may be hearing your microphone signal twice. This happens when hardware zero latency self-monitoring and software monitoring are both active at the same time, sending your mic signal to your headphones through two separate paths.
The result is an audible echo or doubling effect. It is not a fault with your microphone or audio interface.
Why this happens
Elgato Wave devices have built-in zero latency self-monitoring: when you speak into the mic, you hear yourself directly through the hardware, with no latency. This is controlled by the Self-monitoring volume in the device's input & monitoring settings.
Separately, Wave Link can route your mic through the software mixer and send that mix to your headphones. If you have set up a mix that includes your mic input and assigned your Wave device's headphone output as the output for that mix, your mic signal is also traveling the software route.
When both paths are active at the same time, the signal arrives in your headphones twice. The hardware path arrives first with zero latency. The software path arrives a few milliseconds later. The gap between them is what you hear as echo.

How to fix it
Mute or remove the mic from the mix
The way to resolve this is to remove your microphone input from the mix that is using your Wave device's headphones as the output — typically your Personal Mix.
- Open the mixes view in Wave Link.
- Find the mix that has your Wave device's headphone output assigned to it.
- Mute the microphone or remove the routing from the mix entirely.
Your mic will no longer play back through that mix, so only the hardware self-monitoring path remains. You will still hear yourself in your headphones, just through the direct hardware path with zero latency.
