Although worked fine in the past. I am not getting sound from my MacBook Pro speakers during a zoom meeting. I tried my headphones and they worked fine. I disconnected bluetooth and tried again...no sound from speakers. Tried help topics at Apple and Zoom, no solutions found. Quit Zoom, signed in again, no change. Updated software, no change. 

I tried to update the Zoom app on an elderly, home-bound friend's Galaxy tablet but got into an unending circle of messages that I had updated the app to following refusals to connect to a Zoom meeting because the app needed to be updated. My friend's account shows that she has Zoom version 5.4.9 (1079) in spite of my efforts to update it to at least version 5.8.6. What is the problem? Perhaps that the tablet is too old/too limited in memory or whatever to update? Help, please! Zoom is one of the few ways my friend can still connect with others directly.

Why don't I see " Slides as Virtual Background" in my Zoom settings? (running the latest version Version: 5.7.6 (1320))

I followed along with the process below

Hallo zusammen, ich habe folgendes Problem:

Ich habe Video in Deutsch/Englisch. Dabei ist der linke Kanal englisch und der rechte Kanal ist deutsch. 

Jetzt will ich im Dolmetscher-Modus den einen Kanal abspielen und im Hauptmodus den anderen Kanal. 

Leider funktioniert die Stereo-Funktion nicht wie erwartet, sondern die Kanäle werden vor dem Streamen gemischt und dann als gemischte Kanäle verteilt.
