Microphone difference between before and after sharing

[eco]

There's so much difference between before and after sharing
It seems that the output of the microphone is properly communicated to the other person before performing the sharing, while the output does not appear to be generated after performing the sharing

The reasons are as follows
1. Microphone volume before and after sharing (green up and down) is different
1.1 Before sharing, the microphone volume motion was improved, and the output was improved and communicated well
1.2 When shared, the microphone volume goes down and slowly goes up shallowly, and the output doesn't work

How can we fix this phenomenon?
