Clearing the TutorASAP Cache

TutorASAP  stores the downloaded files and images in a temporary cache on your computer, similar to your web browser cache. On a Windows PC you can clear this cache by right-clicking on the Groupworld icon in the system tray (at the bottom-right of your screen, near the clock) and choosing ‘clear cache’. On a Mac, you can clear the cache by deleting the ‘groupworld_data’ directory that is created on your disk (inside your home directory).

Using the Audio/Video Conferencing

The conference room can support up to 3 users by default, each with video and/or audio. More users can be supported if the room is configured to have a single presenter user. If you have enabled your webcam, your preview window will appear at the top, with the audio controls underneath. The other users will appear in the windows to the bottom. If you see a message saying “Video Disabled” instead of seeing yourself, it just means that the room you are in has been configured to not have video.

Your video is transmitted automatically to the other users. By default the frame rate is set to 4 frames per second and increased to 8fps when speaking. This can be configured when the room is created.

Audio is only transmitted to the other users when you are speaking. The recording circle (under the video preview window) should light up red when you are speaking and your voice is being transmitted, and it should be white when you stop speaking. If this does not happen, you may need to adjust your microphone volume up or down. You will also see the red bar under your video window move to the right when you are speaking – generally it should move about 30-50% to the right if your microphone volume is adjusted correcty. Alternatively you can use “push-to-talk” mode: simply untick “Auto Transmit Voice”, then click and hold the left mouse button on the recording circle when you want to speak.

Audio/Video Troubleshooting

Audio not working at all – if you don’t see a red circle light up under your name when you speak, try clicking and holding the mouse button down inside the recording circle under your name. If the recording circle does not turn red, it means you have answered NO to the ‘enable audio’ question when logging in so you will either need to log in again (and maybe clear your cache if it doesn’t ask you the question because you ticked ‘always choose this option’). If you do see the red light when you click and hold the mouse button down in the recording circle but you do not see the red bar moving to the right it means your microphone is not working. Check to make sure that your microphone/headset is plugged into your computer and correctly configured:

Tutorial for configuring sound input device on Mac OS X

On a Windows PC you can test in the Windows Sound Recorder (normally in start menu->programs->accessories->entertainment) – if you can record your own voice and play it back in Windows Sound Recorder then the audio should also work.

Echos – delayed echos are an indication that there is feedback (the speech is coming out of a user’s loudspeakers and entering their microphone). In general, if you hear screen480x480 (1)a delayed echo of your own voice, it means there is feedback from the other user’s microphone (i.e. their voice is coming out of their speakers and into their microphone again). This can be solved by ensuring that all users use headsets or headphones rather than loudspeakers. If this is not possible, the problem can be reduced by ensuring that all users untick “Auto Transmit Voice”, and use push-to-talk.

Echos can also be caused by an incorrectly configured Windows sound card – if you have not selected a default recording device under Windows, sometimes it will record from the headphones as well as the microphone resulting in the other person hearing an echo. The solution is to make sure your microphone is selected as the default recording device. This is never an issue on a Mac.

Note that some headsets have poor-quality electronics resulting in crosstalk, which will cause echos for the other user. If you hear a quiet echo of your own voice and the other user is using a headset, this is a likely cause.

If you hear an immediate echo (with no delay) of your own voice, it generally means that your sound card is not configured correctly, and you will need to make sure that your microphone is muted in the Windows playback volume settings.

Also make sure you are not logged in twice with two Groupworld windows open, as that will cause you to hear an echo of your own voice.

Garbled Audio – generally this is caused by network jitter (i.e. your internet connection slowing down and speeding up). Make sure you have a good quality internet connection. If using desktop sharing, bear in mind that it can use a lot of bandwidth and might affect the audio. Note that by default Groupworld uses no buffering (like skype). This results in low latency but potential garbled speech if there is internet jitter. If you prefer you can configure your Groupworld rooms to have buffered audio – audio will always be perfect (no loss), but there might be delay (to do this, simply change the buffering value from 0 to 1 when configuring the room).



Audio Break-ups – if you hear break-ups (small gaps) in the sound, it can have one of two causes. If parts of the speech are missing, it means that the talking user’s microphone volume is too low for the automatic recording threshold or the user is speaking too quietly. That user will need to either increase their microphone volume (and maybe tick “mic boost” in the Windows advanced volume control), or else just click and hold the mouse button inside the recording circle when they want to speak. If no speech is lost and you simply get pauses in the sound, it means that the packets are getting delayed. Check to make sure that you are not using any applications that are using your internet bandwidth (such as file sharing apps), and also make sure you have sufficient bandwidth (see the client system requirements). Also note that the audio will get paused on Windows when you are uploading documents (using the ‘Upload document’ feature), whenever any error or yes/no dialog boxes are on-screen, or when you are dragging or resizing any Groupworld windows such as the chat window. Also check to see if any other programs are using excessive cpu time on your computer (press the ctrl+alt+delete keys and bring up Task Manager on Windows, or load Activity Monitor (inside Utilities) on a Mac). Sometimes virus checkers and system updates can be using a lot of your computer’s resources in the background without it being obvious.


Video Delays – if you experience very large delays in seeing another user’s video (more than a few seconds), it generally means that one of the users has insufficient bandwidth (usually the person sending the video). Check the client system requirements for more info.


Sound Delays – you should never get delays of more than one or two seconds during normal usage. If you do get large delays, it can be caused by one of two things. First, delays can be caused if your internet connection is dropping packets (use pingtest.net to check) or is too slow (use speedtest.net to check). Delays can also be caused if some other program on your computer is using excessive cpu or network resources, or if you are using the ‘upload document’ feature or moving/resizing a Groupworld window, or if an error box is on-screen – see audio breakupstroubleshooting above for further details.
