I am facing audio/video & screen sharing problems while using the Virtual Classroom on Google Chrome browser.

WizIQ users who are running the Virtual Classroom on certain versions of Chrome browser may experience a delay in audio and video streaming, even with sufficient internet bandwidth.
You can use one of the following fixes:

Fix 1

Upgrade your Google Chrome browser to version 28.0.1500.72 or above. Alternatively, use Internet Explorer, Firefox, Safari, or Opera browsers.

Fix 2

In the existing Chrome (below version 28.0.1500.72), disable the default Flash Pepper (PPAPI) plugin by following these steps:

Type chrome://plugins in the browser tab.
Click + to expand Details in the upper-right area of the screen.
Locate the Shockwave Flash plugin in the list.
Ensure that Shockwave Flash plugin of Type: NPAPI, is in the list and it is enabled.*
Now locate the Shockwave Flash plugin of the Type: PPAPI (out-of-process).
Click Disable for the PPAPI Flash plugin.
Re-launch the browser.

* If you do not have NPAPI type of Shockwave Flash plugin, then download the latest version of the Flash Player from Adobe. On the download page, you may see a message: Adobe Flash Player is built-in but has been disabled. Ignore this message and uncheck the “Yes, install McAfee Security Scan Plus – optional” option before downloading the Flash Player.

I can't hear properly or there is a lag/dropped words in the voice or jerky video?

Lag or dropped words in the voice occur due to slow Internet connection or high CPU usage.
Check speed of your Internet connection using the system configuration test listed above.
Close a few or all applications that you don’t require in the class to free system memory.

No one can hear me?

If you are an attendee, ensure that the presenter has allowed you to use mic.
Test your microphone in audio tests; make sure your mic is plugged in and is working.
Check your microphone is not muted.
If a particular attendee is not able to hear you, suggest ensuring
if the speakers are unmute and level of volume is sufficient.
