Loss of sound in calls

Hello. 
My computer loses sound when I'm in the middle of a zoom call, it won't let me switch to another sound source and the only thing that works is restarting the computer. I have contacted asus and Microsoft, who have done everything but the problem still persists.
The last solution was to install a previous version of zoom but yesterday unfortunately it happened again. This is sporadic, I don't know when it will happen, but I can conclude that it is once a week. What else can I do? It is uncomfortable in the middle of a conversation to lose the sound and ask to wait to restart it.
