How do I fix audio feedback (echo, static) during my session?
If there is echo, static, feedback or any other unwanted noise on the audio connection during your webinar, there are several common issues that could be causing it. Audio feedback is most often caused by an improper placement of hardware or a misconfiguration of software settings.
How to determine the source of the noise
First, it can be helpful to figure out where the unwanted noise is coming from so the right individual can troubleshoot the issue using the tips below.
- If you are connected with your mic and speakers, then there is most likely an issue with your audio device. Try unplugging your headset from the computer and then plugging it back in again. Also see the additional tips below.
- If you are connected via your telephone, then there is most likely an issue with your telephone service provider. Also see the additional tips below.
Everyone except me can hear the unwanted noise. We hate to break it to you – but the source is probably you! Try using the troubleshooting tips below.
- Click Mute All in the Attendees pane.
- Unmute each attendee one at a time, and have them start speaking.
- When the unwanted noise returns, the most recently unmuted participant can be identified as the source of the echo. They should then try the following troubleshooting tips below.
Troubleshooting for computer mode (mic and speakers)
- Make sure you have selected Computer Audio in GoToWebinar.. If you want to connect with your mic and speakers then you need to make sure GoToWebinar is set to the right mode (or else it will not pick up your audio). See Connect to Audio using the Internet (Mic and Speakers) to learn how to select Computer audio.
- Try a USB headset. The built-in mic and speakers on your computer or mobile device might not pick up your audio as clearly as a headset, because built-in microphones on your computer or webcam can pick up other noise and cause an echo. We recommend a using USB headset plugged into your computer (instead of an analog-connected one), or headphones with a mic included plugged into you mobile device.
- Try unplugging and replugging in your mic. Try unplugging your headset or standalone microphone from the computer or device and then replugging it back in. If possible, try using a different USB port.
- Try moving the microphone if using a standalone one. If you are using a standalone microphone (i.e., not the built-in one on your computer or a headset), try moving it further away from your mouth. Also be sure to move any hand-held electronic devices (such as an iPhone) away from your mic and speakers, as this can cause feedback.
- Try lowering the volume of your built-in speakers. The built-in speakers on your computer might be playing back the sound that your built-in mic is picking up, which could cause an echo.
- Check for sources of background noise. There could be something in your environment that is causing the unwanted noise, such as a fan blowing directly into your microphone or other voices if you are in a public area. If you cannot move away from these sources of noise, then try muting yourself when you aren't speaking.
- Mute the microphone when you aren't speaking. If you weren't able to resolve your feedback issues, then try muting yourself when you aren't speaking to avoid having the unwanted noise disrupt the session.
Troubleshooting for phone mode
- Make sure you have selected Phone Call in GoToWebinar. If you dialed in with your telephone but GoToWebinar thinks you are using Computer audio, then it is probably picking up your audio from both sources! See Connect to Audio using your Telephone to learn how to select Phone Mode.
- Try hanging up and dialing in again. An unknown issue might have occurred when you connected to the audio conference. Try dialing in again to see if the connection is better.
- Stop using speaker phone. If you are using speaker phone, try switching to regular mode or using headphones instead. The speaker phone might be causing unwanted feedback.
- Try a different telephone. There might be an issue with your telephone itself. If you are using a cell phone, try using a land line phone; it's possible that you have low cell service. If you are already using a land line phone, try using another one if it is available.
- Avoid multiple connections in a single room. If there are multiple people in one room who are each connected using their own telephone, try these tips:
- Have each person use headphones or a headset instead.
- Have individuals move into different rooms to avoid picking up each others' audio.
- Have everyone share a single phone line (or speaker phone) and hang up on the other phones.
