why do I have crackling sound on teams calls

Crackling sounds during Teams calls can be caused by several factors, primarily related to network conditions and audio hardware. Here are some common reasons:

1. Network Issues: Poor network connectivity can lead to audio quality problems, including crackling sounds. High latency or jitter can cause interruptions in the audio stream.
2. Microphone Problems: A faulty microphone or issues with the microphone settings can also result in crackling noises. Ensure that the microphone is functioning properly and that it is not muted or malfunctioning.
3. Browser Audio Processing: Sometimes, the browser’s audio processing module may deteriorate audio quality, leading to crackling sounds.
4. Device Compatibility: Incompatible or malfunctioning audio devices, such as headsets or speakers, can contribute to audio issues.

To troubleshoot, consider running a network quality test and checking your microphone settings and hardware.
