Audio and screen-sharing issue in Webinar (Classroom)

[indiciumconsultancy]

Hi,
It seems I have a strange behavior in the webinar (Classroom) setup. Not able to determine the cause or how to fix it. Hopefully someone on this forum is able to.

Issue:
1. I am not able to hear the attendants audio, but he can hear me fine.
2. Attendant is not able to see my shared screen, but is able to see a shared pdf.

* We have both tested our audio/video using the 3cx settings menu, and both worked correctly.
* The attendant tried joining the meeting in Chrome, Firefox and using the iphone 3CX conference app. All gave the same problem.
* The attendant had made sure to close all programs that might use the microphone to prevent clashes.

I presented the webinar in Firefox on an iMac and had given permission to use both audio and video in the firefox security popup.

Thanks for any assistance.

Hi there,

I've gone ahead and performed a couple of manual checks for both the audio and the screen sharing issues on all MCU meeting servers with no success in reproducing what you're reporting.

You previously opened a thread and reported the issue was fixed. I suppose it wasn't? Please provide the following info:

1) Not to mention the obvious, but, do you possibly have Chrome muted from the windows audio mixer?

2) Weak PC? Could be that your CPU is bricked at 100%? If that's the case, video/audio will have issues.

3) When you and the other participant use the "Device Test" under settings, do you both see and hear yourselves?

4) What MCU are you connecting to? You can see this under the meeting settings in the info tab.

5) Can you both press F12 while inside the WebMeeting and go to the "Console" tab? Once there, try to screen share and enable/disable your mic/video from the WebMeeting UI.

Errors and generally anything in red text appearing here is considered abnormal and not expected. If anything like that appears in the console, please PM it to me.

Hi, Thanks for taking the time and trying to get to the source of this issue.

Yesterday I tried to tackle again this problem with the user, and it worked fine. Nothing he changed or me, it is just strange it happens one day and is fine the other. Unless you have a better idea, I will try a few more times, seeing if it happens again and than perform the above mentioned steps.

I will get you posted.
