I'm making a small push to talk application, I'm relying on boardcast to do it. My FE has 2 peer connections 1 sendonly , 1 recvonly. Of course all connections were successful. When a person speaks, they will create a sendonly peer connection and send the track to the server to receive the track on ontrack and write it to localTrack. Listeners when joining to create a peer connection recvonly hear normally.
The error occurred when I switched the speaker to B. Before creating a sendonly connection for B, I closed A's sendonly connection. So the previous peer conenction recvonly could not hear. But peer conenction recvonly then hears normally again. One more important point is that after a few minutes of speaking, the peer connections that were previously unable to hear will be able to hear again.

Your environment.

• Version: v4
• Browser: chrome
• Other Information - reactjs webrtc

What did you do?

I have checked that localTrack is writing data successfully. I checked the stats of the previous peer connections and did not see any change in data bytes.

What did you expect?

I want when changing speakers to write to localtrack, previously connected recvonly peer connections receive the new audio data bytes and hear them.

Thanks.
