Although there can be various causes for this issue, mainly Discord picks up the in-game and system sound due to Stereo Mix being enabled. This is because the Stereo Mix combines output and input audio, resulting in Discord picking up every sound that your computer plays. Other causes can include incorrect microphone settings, faulty audio drivers, or high microphone sensitivity, which can cause the mic to pick up sound from the headset. With these causes in mind, let’s have a look at the solutions to this issue.
Quick Fix
If you’re using the Realtek Audio Console, make sure to enable Acoustic Echo Cancellation to prevent your microphone from picking up audio from the speaker.
1. Disable Stereo Mix
As mentioned earlier, Stereo Mix combines all audio output from your system. When this is enabled, Discord can treat it like a microphone, transmitting all system audio along with the voice. By disabling this feature, you stop the merging of the input and output devices, allowing Discord to pick up only your microphone.
2. Reconfigure Output/Input Devices in Discord
If the incorrect audio device is selected, for example, if you choose Stereo Mix instead of your microphone as an input device, Discord will pick up both your in-game and microphone audio simultaneously. This will result in your teammates hearing both you and your in-game sounds. Therefore, make sure to select the correct input/output devices. Another thing you can do is to enable Noise Suppression and set it to Krisp. This will prevent your headphones from leaking the game audio.
3. Check and Adjust Microphone Sensitivity
Adjusting the microphone sensitivity can help reduce background noise, particularly sounds from your headset, from being picked up. If the microphone sensitivity is too low, it can disturb your communication with teammates and affect their game. So make sure the microphone sensitivity is neither set too high nor too low.
4. Give Exclusive Control to the Microphone
There is a possibility that Discord does not have exclusive control over your microphone, perhaps because it is taking multiple input sources. To fix this, you need to give exclusive control of your microphone to Discord to avoid this issue.
5. Update or Reinstall Audio Drivers
If you have outdated drivers or if audio drivers have been corrupted by a third-party program, you need to either update or reinstall the driver. This will replace the old driver and resolve the corruption that might be causing the issue. To do so, follow these steps:
