Why do I hear myself
Stop an echo while streaming — device speakers, Windows mic monitoring, host speakers, voice chat on the host and virtual mixers.
Hearing your own voice a beat late is a loop in one of five places. Check them in order; the first two cover most cases.
Your device's speakers
Your device's microphone picks up the stream playing from its speakers and sends it back.
Use headphones. Echo cancellation in client settings is on by default and removes some of it; how much depends on the device. To stop talking for a moment, mute your microphone without leaving the stream.
"Listen to this device" and app monitoring (Windows hosts)
Windows or an app plays the Punktfunk microphone out of the host's speakers, and the stream sends it back.
- Windows: Sound settings → More sound settings → Recording, double-click Punktfunk Microphone, and on the Listen tab untick Listen to this device.
- Apps: turn off microphone monitoring, such as Discord's Mic Test or OBS's Monitor audio on a mic source.
The host's own speakers
With Host → Where audio plays set to Device and host, your device's microphone hears the host's speakers when you stream from the same room. Set it back to Device only, or turn the host down.
Voice chat running on the host
Friends streaming in hear themselves when a voice app runs on the host, because the stream carries its playback. Set Host → Voice chat to On the host: Voice chat while they play.
Virtual mixers (VoiceMeeter and friends)
A VoiceMeeter strip that hears the Punktfunk microphone and feeds the streamed output makes a loop. Take the microphone off every strip that reaches that output.
