Some participants cannot hear 1 of the interpreters on the Spanish channel

[Joneyla]

Hello!

Hopefully there's someone out there that can help me.

I am a Spanish conference interpreter. Lately when using the interpreter feature "some" of the participants cannot hear me on the Spanish channel.  However, everyone is able to hear the other interpreter that I partner with.  This was not always the case, I never had this problem before. 

Does anyone know how to remedy this? Or why this maybe happening? Should I uninstall and reinstall?

Please HELP!!!
