crackling sound on my laptop Microsoft team

Dear @ei pwint phyu,

Thank you for posting your question in the Microsoft Q&A forum.

Based on your description, you wonder why Microsoft Teams produces crackling audio on your laptop when sharing system sound, while Zoom and your phone work normally.

The issue is likely related to Microsoft Teams desktop audio processing or your laptop’s audio configuration, rather than hardware.

Here are some suggestions you can try:

Adjust Teams audio settings

• Open Teams > Settings > Devices
• Set Noise suppression: Switch on
• Confirm correct speaker device

Reduce system load during sharing

Close unnecessary apps and browser tabs Running many applications can degrade shared audio quality

If the issue still persists, could you please confirm:

Which version of Teams is affected (Teams desktop app or Teams web)? Have you tried switching to another version to check whether the issue still occurs?

When you share the audio file, do all students experience the issue, or only some specific students report that the sound is unclear?

Is the audio file a pre-recorded file, or are you playing it live during the session?

If it is a recorded file, did you use any devices such as a microphone or headset when you recorded it?

For reference Fix distorted or crackling audio in Windows

Looking forward to your update.
