Troubleshooting

Using system settings to enable two USB headphones on Windows 10 and 11:

1. Open Control Panel, click on Hardware and Sound, and then choose Sound.
2. Choose the Playback tab and select the first headphones as the default playback device.
   • Depending on how the headphones are plugged in, one should read 2-USB Audio Codec, the other 3-USB Audio Codec. Knowing which headset is plugged into which USB port will help with the identification of the examiner and examinee headphones.

Change the name of the device to make it easier to identify. Once the new name is entered, click Apply and then OK. Repeat this step under the Recording tab to rename the microphones to match.

4. If there are no devices, or not all devices show up, right-click on the empty area and enable “Show disabled devices.”
5. Make sure that the microphones for both headsets appear and are enabled. To enable the headset microphones, right-click on the corresponding microphone and select Enable.
6. Double-click on the Examinee’s Microphone to open Properties.
7. Choose the Listen tab.
8. Check the “Listen to this device” box and select the second headphones (Examiner’s) from the drop-down menu, click apply, then click on the Advanced tab and uncheck the “Allow application to take exclusive control of this device”; click Apply and then click OK.
9. Next, repeat step 6-8 for the Examiner’s Microphone.
   • Double-click on the Examiner’s Microphone to open Properties.
   • Choose the Listen tab.
   • Check the “Listen to this device” box and select the first headphones (Examinee’s) from the drop-down menu, click apply, then click on the Advanced tab and uncheck the “Allow application to take exclusive control of this device”; click Apply and then click OK.
