Shared audio cutting off everytime I speak

Hi, @Xeroz 

As RachelGomez123 said, it may have to do with the other party's microphone and speaker settings.

If the other party is using a mic speaker, the mic speaker may be the cause.

I had received report of the same phenomenon and have implemented the cause and remedy.
I solved the problem by lowering the speaker volume of the microphone speaker.

The causes of the audio cutoff include
The speaker volume is too loud and the microphone collects reflected sound from walls and ceilings. The microphone is temporarily and automatically muted to cut off reflected sound that is too loud to be beyond the normal control range.
The countermeasure could be taken by lowering the microphone volume, but the microphone speaker was of a type that interlocks the speaker volume with the microphone volume.

The voice communication at that time was a telephone , so it was clear that it was not a network problem.

Hello there, 

I know this comment is coming three years after 😥. However, I thought to share my findings, just in case you still experience this issue. Or for anyone who might find it useful.

So I also had this issue when testing out the "Share computer audio" feature.. After many trials and troubleshooting, I realized that for the Audio share to work effectively, without the background music clipping when someone speaks, whoever is sharing audio should disable the audio join on the device. This can be done by clicking the up arrow icon in the Mic box, and then clicking "Leave computer audio". There seems to be an interference between the mic/speaker and computer sound being shared, which causes the audio to clip/cut off when anyone speaks.

I hope this helps someone. Cheers 🤗
