Check DingTalk Meetings Speaker Settings

In the DingTalk meeting window, go to More > Settings > Audio. Check whether the correct speaker is selected and whether the volume is set high enough. Use the test function to verify that the speaker works normally.

​

Check Whether Screen Sharing Includes Audio

If the current speaker is sharing their screen, ask them to check whether Share Computer Audio is enabled.

Check DingTalk Meetings Microphone Settings

In the DingTalk meeting window, go to More > Settings > Audio. Check whether the correct microphone is selected and whether input volume is high enough. Speak near the computer microphone and check whether the microphone level moves.

Noise During a Meeting

Noise generally falls into three scenarios:

1. All or most participants hear noise.
2. Only one specific participant hears noise.
3. Some participants hear noise while others do not.

​

Scenario 1: Everyone or Most People Hear Noise

This is usually caused by one participant’s microphone picking up noise.

1. The host can check noise reports, mute the reported participant, and ask them to self-check.
2. The muted participant should check whether the environment is noisy. Use DingTalk’s Test Microphone function in audio settings. Move to a quieter location if possible, use a headset if needed, and lower microphone pickup volume.
3. If environmental noise is not the cause, try switching microphones, such as between a headset and the device’s built-in microphone.
4. If there is no noise report, the issue is likely network-related.

​

Scenario 2: Only One Person Hears Noise

Ask that participant to:

1. Close other audio playback apps, such as music players or voice chat tools.
2. Use DingTalk’s Test Speaker function to check playback volume and device status. If playback is abnormal, replace the playback device, such as switching from speakers to headphones.
3. If test playback is normal but meeting audio stutters or changes speed, the issue is likely downstream network quality.

​

Scenario 3: Some Participants Hear Noise

This is often multiple cases of Scenario 2. The host can ask affected participants to run the same checks.

​

Audio Stutters, Speeds Up, or Slows Down

This is usually caused by network connection issues, such as network card problems, other high-bandwidth apps, weak uplink quality, jitter, or congestion.

1. First rule out environmental or device issues by following the noise checks above.
2. Check Wi-Fi or mobile signal strength. If the network is poor, switch to a better network or join by phone if available.
3. If the network card is uncertain, test communication in another app.
4. If the issue persists, turn off high-bandwidth features such as video and screen sharing to prioritize voice quality.

​

Echo During a Meeting

Echo can be local echo, where you hear your own voice return, or remote echo, where another participant hears their own voice.

1. For local echo, first rule out system configuration issues or multiple devices in the same room. Ask other meeting rooms to check for remote echo leakage.
2. For remote echo, ask the affected room to mute its microphone or speaker to determine whether that room is the source. If the echo stops, keep the microphone and speaker farther apart, avoid obstacles within 30 cm of speakers, keep speaker volume below about 80%, reduce microphone pickup volume, and use external microphones where possible.
3. If echo continues, open the microphone only when speaking, use a headset for solo attendance, or leave and rejoin the meeting.
