Hey @khanmdmudassir,

Thank you for providing additional information. That’s interesting to hear that it was working for some on v1.8.3 and not others. I still think this is related to the update but I can’t pinpoint exactly why that would be. If you see this issue in the future, on v1.8.5+ please reach out and I’ll investigate it further.

> One last question, I would like to know why Zoom included the **“AES 256-bit GCM encryption”** as it was working fine before. Any article reference link will help. Thanks!

We added the encryption to the Web SDK to better align with our goals to make Zoom the most secure communications platform and to match the functionality of the desktop client. We added this encryption to our desktop client [in April](https://support.zoom.us/hc/en-us/articles/360042279352-New-updates-for-April-25-2020#:~:text=Zoom%20is%20upgrading%20to%20the,Webinar%2C%20and%20Zoom%20Phone%20data.) and this helps bring feature parity between the two.

Here is some information on our efforts to improve security and this change:

> [@(ACTION REQUIRED) Web SDK update version 1.8.5](https://devforum.zoom.us/t/action-required-web-sdk-update-version-1-8-5/39004):
>
> Hello Zoom Developers, here are the updates for the Web SDK version 1.8.5 release: Please note that as of January 10th, all older versions of the Web SDK (versions 1.8.3 and below) will no longer have computer audio functionality within meetings. Please upgrade to version 1.8.5 or above to avoid service disruption. To complete alignment with Zoom’s security initiative, including the new AES 256-bit GCM encryption, we will disable un-encrypted audio within meetings that are not using AES 256-bit…

I hope that helps!

Thanks,
