For certain test sections, you will need a headset with working microphone and speakers. For the best experience, use USB headsets with microphones for both of these sections. Other headset and microphone options work, but may require more preparation steps by IT representatives due to being more dependent on the local configuration.
Prior to testing, have an IT representative test and configure the headsets for each computer. Configuring a USB headset may be as simple as plugging it in. To check that audio streaming and recording are working, please take an Avant Technology Check.
Instructions for configuring sound are available through the computer’s operating system Help facilities. On the configuration screens, make sure that the headset is selected and the volume levels are set appropriately.
USING THE HEADSETS
The Testing Coordinator should ensure that arrangements have been made for the headsets to be plugged in before starting the test, and that test takers know how to use the in-line controls on the headsets, if available.
ADJUSTING MICROPHONE LEVELS FOR MAC OS AND WINDOWS
If you are receiving a low mic or low volume error message while recording in the Speaking section you may need to adjust the sound settings in your preferences.
1. Open System Preferences by clicking the Apple menu and selecting System Preferences.
2. Locate and click on the Sound preference pane.
2. From the Control Panel, locate the Hardware and Sound settings and open it.
3. Once the Sound Preferences are open click on the Input tab.
3. From the Hardware and Sound section, click on Sound to open the system settings for your audio devices.
4. Locate the attached headset and ensure it is the active input device (using the Internal Microphone is not recommended in a lab setting).
4. Navigate to the Recording tab of the Sound properties panel. If the external microphone is not currently set as the default on the Recording tab, be sure to set it now. Right mouse click and choose “Set as Default Device”.
5. Adjust the Input volume slider until the input level graph shows movement during normal speaking with the microphone at an appropriate distance from the speaker.
The microphone gain should now be set properly to allow students to record their speaking responses. Close System Preferences when done making changes.
5. Double click on the external microphone from the list to open its settings panel.
6. If the slider is set too low, raising it to a higher gain will improve audio quality for speaking responses. Change the slider to a higher gain then press OK.
7. From the Sound Panel, speak normally into the microphone and note whether or not the green input graph shows that it is registering your input. If it is not, double-click the microphone and raise the gain until it does so.
The microphone gain should now be set properly to allow students to record their speaking responses. Close the Control Panel when done making changes.
ADJUSTING MICROPHONE LEVELS IN CHROME OS
Unfortunately, it is not possible to adjust the microphone sensitivity in ChromeOS. For issues with recording in ChromeOS, we recommend trying an alternate headset, asking the test taker to speak with additional volume, or to move closely to the microphone. If recording issues persist, moving the tester to an area without background noise may be needed
TROUBLESHOOTING RECORDING ISSUES
Ensure the headset is plugged in
Check that the microphone is not muted – many headsets have a mute button on the set itself, or on the wire that is connected to it
Check that the volume on the microphone is not turned all the way down
Make sure the test taker is using a supported browser (Microsoft Edge, Chrome, Safari)
Try refreshing the page
Stop the test and close the browser window, then restart the browser and log back in
Try a different browser
Try unplugging the headset and plugging it back in during the test (for USB headsets)
Ensure that “Allow” is selected in the browser site settings allowing the use of the microphone in the test
Check to see if you can record sound in a different application on the computer
If only one or two test takers are affected, try a different headset or a different computer
If students log into student accounts on the computers, make sure that the student account for logging into the computer does not have restrictions that would affect recording
