**Description**  
One of our users reported that suddenly he **couldn’t hear** the host from around 18:36 JST of the meeting. Host can hear the other user though. Upon checking the meeting’s audio metrics on Zoom dashboard, I noticed that the **audio bitrate suddenly dropped** from 50 ~ 100 to just 12kbps. Video metrics looked stable though.

May I know what are possible causes of this issue?

**Error**  
N/A

**Which version?**  
1.8.1

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:

1. Host and client join the meeting

**Screenshots**  
None

**Device (please complete the following information):**

- Browser:Chrome

**Additional context**  
Possible related thread [Hear audio with lag](https://devforum.zoom.us/t/hear-audio-with-lag/34374)

I’ll be sending the meeting ID by email.
