As video conferencing becomes more widely used, the demand for high-quality communication has increased significantly. While many people emphasize the importance of video in these meetings, the truth is that audio plays a crucial role in ensuring effective communication. Most interactions during video calls rely on spoken dialogue or discussions. While clear video is certainly beneficial, it's the audio that ultimately determines the success of the conversation. Even with decent video quality, poor audio can severely hinder understanding and collaboration.
Unfortunately, audio issues are quite common in video conferences due to the lack of focus on audio quality. To help users quickly identify and resolve problems, Xunwei has compiled a list of the most frequently encountered audio issues during video calls and offers practical solutions to address them.
Question 1: The sound is too quiet during the call
One of the most common complaints is that the sound from the other side is too soft, making it difficult to understand what is being said. This issue usually stems from the microphone or audio input settings. To troubleshoot, start by testing your own speakers or headphones. Play a test audio file through your computer to ensure the volume is sufficient. If the playback is fine, the problem may be on the incoming audio stream. Adjusting the recording volume on your device is often the key, though many users overlook this step. Simply increasing the speaker volume without adjusting the microphone level won't solve the issue effectively.
Question 2: Excessive background noise during the call
Noise during a call can come from two main sources. First, ambient sounds like fans, air conditioners, or traffic can interfere if the audio equipment lacks noise suppression features. Second, if the microphone is set to a high sensitivity level, even small movements can cause loud background noises. Some video conferencing software includes noise reduction or squelch functions, but conflicts between these features and the hardware can sometimes worsen the problem. It’s important to check both the environment and the software settings to minimize unwanted noise.
Question 3: Hearing your own voice during the call
Echoes or feedback during a video call can be very distracting. This typically happens when the microphone picks up sound from the speaker, especially in environments where devices are not properly positioned. Even with built-in echo cancellation features, real-time audio systems may still struggle to eliminate all echoes. To reduce this, try moving the microphone away from the speaker or lowering the input sensitivity. In some cases, adjusting the distance between the sound source and the microphone can significantly improve the clarity of the call.
Question 4: A buzzing or harsh sound during the call
This type of noise, often described as a buzzing or hissing sound, is commonly caused by feedback or howling. Two main situations can lead to this: either the local speaker is picking up its own output, or there is an echo between the remote parties. To fix this, first, disconnect the call and test the speaker directly. If the sound is still present, adjust the audio output settings to prevent the microphone from picking up the speaker’s sound. For echo-related issues, ensure that both ends have proper echo cancellation enabled.
Question 5: Audio is choppy or distorted during the call
If the audio cuts in and out or sounds unclear, the first step is to check the network connection. Poor internet performance can cause delays or packet loss, leading to broken audio. Ensure that your network is stable and that no other applications are consuming excessive bandwidth. If the problem persists, restart the software, as conflicts between different apps—such as QQ or Zoom—can also cause audio issues. Sometimes, the main host must enable specific features to allow full participation from all users.
Question 6: No sound is coming through at all
When no audio is heard, start by checking your local setup. Test your speakers, headphones, and microphone to ensure they are working correctly. If everything seems fine, the issue might be on the remote end. Confirm that the other party is sending audio and that their microphone is not muted. Additionally, make sure that the correct audio input device is selected in the video conferencing software. Some platforms require specific permissions or settings to allow audio transmission, so double-check those configurations.
Question 7: Audio is muffled or unclear
Muffled or distorted audio is often caused by software conflicts or improper configuration. For example, launching video software after connecting to a microphone can create compatibility issues. To resolve this, close all unnecessary programs before starting the call. Also, ensure that your audio drivers are up to date. If the problem continues, try using a different microphone or audio device to see if the issue is hardware-related.
Question 8: Audio delay is noticeable
Audio lag can be frustrating, especially during real-time conversations. First, test your internet connection. If you're on a local network, check for any heavy traffic that could be affecting performance. If possible, limit the use of bandwidth-heavy applications. If the network is unstable, consider reducing the video resolution to prioritize audio quality. Although this may lower the visual experience, it can significantly improve the clarity and responsiveness of the audio stream.
