- You are getting irritated by the background echo while using Voice Changer Software on calls via VoIP apps like Skype/Discord/Twitch… and the other end is unable to hear you clearly.


- Right after launching Voice Changer Software, noise starts and builds up in feedback loops until it reach the max volume level.

♫ Noise may sound like:

The above sound problems might occur due to many different reasons:

1. The VoIP applications or communicators you are using have not been tested yet and may not work compatibly when using along with Voice Changer Software.

2. Using built-in microphone or separate microphone and speakers can cause howling/buzzing symptoms.

3. Other program(s) on your computer also requires a virtual driver which conflicts with AV Virtual Audio Driver.

4. Failed or corrupted installation of AV Virtual Audio Driver/AV Voice Changer Software.

5. There may be infected or defective file(s) that prevents your computer from being in perfect condition.

Please select appropriate solutions below in accordance with your computer’s status:

1. Check your microphone or headset:

  • It is recommended to use a normal headset plugged directly into your sound card’s ports.
  • If you are using separate microphone and speakers, please keep the microphone as far as possible away from the speakers and as close as possible to your mouth.
  • Do not forget to disable your built-in microphone if you are already using an external headset.
  • Try updating your hardware driver, especially sound card driver.

2. Adjust PC’s Sound Settings:

  • Right-click on the speaker icon at the bottom-right of your desktop screen » Choose Playback devices. Make sure your main speakers is set as default device.
