Check your audio set up. You may have more than 1 mic (i.e. headset and web cam) connected to the computer. You should only have 1 audio unit connected to the computer. DO NOT CONNECT A HEADSET (WITH A MIC) AND A WEB CAM (WITH A MIC). The computer will not know which mic to use. Make sure your speakers are set up in Collaborate.
I cannot see the people on camera during a web conference?
Make sure your video button is turned on in Collaborate. Make sure whoever is talking has their mic turned on.
What happens if my recording playback does not display the Application Sharing and or Web Tour content that occurred in the live session?
There are two workaround solutions to view application sharing or webtour:
A. Playback menu option OR B. Timeline bar option
Playback Option
Click to highlight Application Sharing Started within the listed items in the Kind column. Then click Seek at the bottom left of this window. Close the window using the "X" or by clicking Done on the bottom right. This starts the recording at that point when the Application Share began.
Timeline bar option: Once archive is open, manually move the timeline slider at the bottom of the window to the point in the recording where the Application Share began. This will display the Appshare content that was visible in the live session.
For Web Tour: Follow instructions above; choose Web Tour vs. Application Sharing. We understand that this is an inconvenience and appreciate your patience while we work on a final solution.
Solution:
To avoid this error and view your recording use one of the following options:
· Launch the recording using the session URL/link
· Use the JNLP file; however only use it once
What if during a session the video does not switch when a different person starts talking?
If you only have 2 people participating this will happen, the video will not switch when there are only 2 people. If you have more than 2 people participating and this happens:
*Click on Tools>Click on Video> Make sure “Have camera follow Speaker” is checked.
What happens if I receive an error message “unable to play”?
This error is due to the security improvements made to JNLP files on the Session Administration System (SAS) and Blackboard ELM. In ELM, the "one time use" JNLP file setting is optional and enabled by the Administrator.
What if I hear an echo during a session?
Echo is caused primarily from sound being replayed back through a microphone and or can be related to latency with the connection.

What if I hear an echo during a session?
Echo is caused primarily from sound being replayed back through a microphone and or can be related to latency with the connection.
These issues are typically solved with a couple different methods and via best practices for using our tools.
1) Important, when finished speaking, hit the talk button again to turn off your microphone. This will prevent the #1 reason for echo, which is the sound of another person's voice re-playing back through the open microphone.
2) Latency related to the Internet connection of the user. Recommend adjusting the connection speed lower, for example, for some users, a move from LAN to wireless makes a big difference. That change can be made by the user from within the session.
Click on--Preferences --> scroll down and highlight "Connection"; adjust this lower, ie from LAN to Cable/DSL, or Wireless. Experiment with what works.
3) Related to #2 above, be sure Internet connection is sufficient for the bandwidth requirements of the session. If using wireless, ensure signal strength is excellent. Weakness here causes issues.
3) Related to #2 above, be sure Internet connection is sufficient for the bandwidth requirements of the session. If using wireless, ensure signal strength is excellent. Weakness here causes issues.
4) Due to bandwidth intensive nature of the certain tools, be aware of bandwidth usage when using video and application sharing.
5) Ensure computer resources besides bandwidth are free for the tools the session requires. Close any programs not required for use in the session to free up memory and processing power.
***One note of hope for echo issues. We are working on echo cancellation for a future release of the software as we recognize the need to help our users mitigate this problem.
Can I use any type of headset?
No. It is recommended that you use a USB HEADSET! If you use other headsets you may have audio problems.
When do I need to plug in my headset?
Plug in your USB Headset BEFORE you log in to a Collaborate session. It is important to do this because if you wait to plug in your headset after the session has started you may not be able to hear people speaking during the session. Your computer has to recognize your headset device before you log in.
