I'm having trouble hearing audio in videos shared in Zoom Meetings. I have an Acer Nitro V15 notebook, model ANV15 - 51 - 58AZ, Windows 11, using Zoom Workplace version 6.4.12. However, this problem with the audio has been happening for several versions now.

The problem is when someone shares a video on Zoom and it has audio, the music contained in the video is automatically cancelled, as if it were noise cancellation. Only the voice contained in the video, whether spoken or sung, that can be heard.

I've already checked audio processing settings on my notebook, and removed them all, but the problem continues. I updated zoom to the latest version, tested previous versions, but nothing changed. I looked here on the forum and saw that in one case they asked the host to remove the noise cancellation option in the audio settings if it had it. I made this modification, but I still have the problem.

I've also heard from some friends who use Zoom that this problem happened specifically on other notebook models like mine. But i have a feeling this might be a specific configuration in the notebook that I may not have encountered yet. Could anyone help me figure out how to fix this?

On Monday 29th September 2025, at least five institutions in Finland, as well as some institutions in Norway and Iceland have faced "Warning. The instructors email is invalid(2216). Error Code 2216 - int_edu_{institution specific numbers}" when trying to access Zoom via Moodle LMS as the Moodle instructor role user. This prevents instructors, typically university teachers using Zoom the way they are used to. In addition to this, institution admins are facing "Sorry, your session was expired. Please refresh the page or login again." when trying to configure LTI Pro settings, which are unexpectedly empty.

No problems on Friday 26th September 2025. The issue started on Monday or during the weekend.

Norway and Iceland reports mention this error occurring also in Canvas LMS integrations.

However, there are institutions who use Zoom LTI Pro and Moodle LMS who are not affected by this issue.

We have checked that Moodle site > Site administration > Plugins > Activity modules > External tool > Manage tools > Zoom LTI Pro tool > Edit > Privacy setting > "Share launcher's email with tool" is enabled.

We contacted the Zoom Support and based on their advise we have checked or tried the following:

1. The instructor's email is not yet created in Zoom as a member of your account.
2. The email address used in Moodle is different from what's signed up in Zoom.
3. The access token does not have the sufficient API scopes.
4. Can the Owner or an admin of the account re-authorize LTI Pro in the Zoom App Marketplace again?
5. After checking these, Zoom deemed it necessary to remove-then-reinstall the LTI Pro app in the Zoom account to resolve the issue.

Institutions are now looking into possible problems that may be caused when reinstalling LTI Pro, such as links no longer working in Moodle after the operation, before reinstallation. Has anyone else had this issue outside the Nordics? Does anyone know how to fix this?

UPDATE: The issue was solved on the 1st of October, 2025. The resolution can be found in the comments.
