Select the right input and output devices
If you use multiple audio devices, such as your computer’s built-in speakers, headphones, or external speakers, you may have selected the wrong audio devices.
Maybe GoToMeeting is simply sending audio to the wrong device.
Using the wrong audio device can affect your ability to hear the other attendees and the other way around.
If you use GoToMeeting online, navigate to Settings, go to Audio and check your current audio configuration.
Check your GoToMeeting audio mode
If you use the GoToMeeting desktop app, double-check your audio mode before joining the meeting.
For example, if you want to use your computer’s built-in microphone and speakers, select Computer Mode.
And make sure to disable the option “I don’t need audio.”
Then manually select the audio devices you want to use.
Don’t skip this step if you have multiple audio devices connected to your computer.
Alternatively, you can right-click on your GoToMeeting icon in the taskbar, select Preferences, click on Audio and manually select the devices you want to use.
Then click on Webcam and tweak your video settings as well. The app will automatically use these settings for all your meetings.
If you use GoToMeeting in your browser, launch the service on Chrome.
You may be able to use GoToMeeting on other browsers, but the chances of experiencing various glitches are pretty high.
