I recently noticed a personal room was created on my account, that i did not create.  I discovered it when an unknown device attempted to join the call/personal meeting.  I immediately checked to see what meeting it was trying to join when I got the notification, and that's when i discovered i have personal meeting setup unbeknownst to me.  How do i remove or delete it.  There is not delete option.

I have a new Dell laptop and it seems every time Zoom goes through an upgrade, my speaker drivers get mangled. The first few times the drivers were deleted. I managed to reinstall new drivers. Yesterday after using Zoom I could not vary the sound. It was loud all of the time. 

My meeting is for a few participants from Singapore & one from Hongkong
The Hongkonger could join my Zoom meetings previously but cannot join my meeting recently. 
She shared that she has no problem in joining Zoom meetings from hosts in Hongkong
Kindly advise
Thank you

I join zoom meetings through zoom web via either firefox or chorme. At the starting of each meeting, it shows to update WebSDK to latest version. But when i went to the website regarding that (https://8xmdmkir8ctlkfj8dttx.noticeable.news/publications/meeting-sdk-web-v2-9-0?embed=true) I am stuck as how to update/install it in my device. I also went to another website showing the steps to do it (https://marketplace.zoom.us/docs/sdk/native-sdks/web/build/) but i am really confused. I am a non-coder. I dont know how to run and where to run these codes or what is the difference between NPM & CDN. Kindly please give me a simple solution of software through which i can install or update it without running a code or so
