Hi @wpeng, Thanks for providing the audio. These audio noise often caused by unstable network connection. We are not able to reproduce this issue on our side. Please have a try with the latest version of SDK and see if this issue persists. Thanks! ---

Hi @wpeng, A follow up question: Is this happening with headphones? Is this issue occurs when you are using a different headset? Could you provide the spec of the device you are having this issue with? Thanks! ---

Hi @wpeng, Thanks for the detailed info. The hardware spec should work fine with our Zoom SDK. Wondering if the audio issue is caused by the network. I have forwarded this to the engineering team for further investigation. Thanks! ---
