Question:

Why do interlocutors experience an echo of their own voice and other sounds from my laptop when I use earphones with a built-in microphone on my Asus VivoBook S15, and how can this issue be resolved, considering that it does not occur with my USB headset?

Answer:

When using earphones with a built-in microphone, users may experience an echo of their own voice or other sounds from a laptop. This phenomenon is particularly common in devices like the Asus VivoBook S15 and can be quite disruptive during conversations. The echo is typically caused by audio feedback, where the microphone picks up the sound from the earphones and transmits it back to the speakers, creating a loop.

–

Microphone Sensitivity

: The built-in microphone may be too sensitive and pick up audio output from the earphones.

–

Audio Settings

: Incorrect audio settings on the laptop can cause the microphone to play back the audio it picks up through the earphones.

–

Hardware Compatibility

: Some earphones may not be fully compatible with the laptop’s hardware, leading to audio feedback issues.

Solutions to Resolve Echo:

–

Adjust Audio Settings

: Check the sound settings on your laptop and disable any features that may be causing the echo, such as microphone boost or audio enhancements.

–

Reposition Microphone

: Move the microphone away from the earphones to prevent it from picking up the output sound.

–

Use Echo Cancellation Features

: Some applications, like Discord, have echo cancellation features that can help mitigate this issue.

–

Update Audio Drivers

: Ensure that your audio drivers are up-to-date, as outdated or corrupt drivers can cause sound processing issues.

–

Hardware Check

: Test the earphones on another device to see if the issue persists, which can help determine if the problem is with the earphones or the laptop.

In contrast, USB headsets typically have better echo cancellation due to their design and the way they interface with the computer, which might explain why the issue does not occur with a USB headset.

By understanding the causes and implementing these solutions, users can effectively reduce or eliminate the echo experienced during audio playback and communication on their Asus VivoBook S15 or similar devices.
