Problems with microphone and BBB

[Miguel Correia]

Hi guys,

Hoping that someone can bring some light upon this issue, I  belong to an IT support Team and one of our users as an issue connecting the microphone to a BBB session.

I already tried to troubleshoot it, but still unsuccessful.

OS Windows 11 24H2
The issue happens both in Edge or Chrome, both apps are updated and both have permissions to use the microphone, I checked twice.

- In MS Teams everything works fine, this only fails with browser and when using BBB. 
- Reboot didn't help, after SFC and DISM (to clear any file corruption)

Problem as shown in picture, the message on top is in Portuguese saying that the microphone is in use, while the only app using it is the browser.
In device manager, everything looks ok.



Any ideas?

Hi,

yeah, the first "idea" is for you to tell the community which version of BBB you're using and on which hardware.

After that, are you using a stun/turn server?

And, last but not least, have you updated the mic's drivers? The error seems to be pointing in that direction.

Regards,

Hi Jean, 

The problem may appear if your company uses cloud firewall like Zscaler , Netskope or an antivirus + firewall , please try to disable them and check.

We're a MoodleCloud user so we use the BlindSideNetworks hosted BBB. Currently this is   BigBlueButton version: 3.0.8 

We're receiving the same error message with some of our learners based at a specific site. I will ask them about zscaler interestingly they are able to use websites like https://www.onlinemictest.com/

Learners are able to enable their microphone in the browser permissions request,

The echo test works and they can hear themselves.

They then try to join and receive the screenshot above.

I'm working out how to proceed with the employers IT team to find a solution that works for them and gives the learners access.

Oh and I forgot to add yes there is a StunTurn server on the BlindSideHosted version of BBB.

Hi everyone, the way we solved this was a bit weird, but it turns out that a feature was turned off in Windows 11, so everything worked out when we found that toggle. I will share it below:

Ahh thank you for updating. Unfortunately this was already toggled on for these learners so must be a different issue.
