Can't hear or be heard clearly on your Webex conference?
This guide will help you:
Check audio settings
Check audio connections
Check volume
Help with echo cancellation
Setup a phone connection — So you can get work done now, and troubleshoot later.
Before You Begin:
If you're using a headset, make sure it's plugged into your computer.
If you're using an external speakers and microphone, make sure they're plugged into your computer.
2. I Can Hear Others, but They Can't Hear Me
In most cases, if you can hear your colleagues but they can't hear you, either your microphone is muted, or not plugged in.
Check Audio Source
Since you can have multiple microphones, it's important to tell Webex which device you are actually using.
While on a conference, select the Audio menu, then select Speaker, Microphone and Camera.
For Microphone, select the mic you want to use. If your mic isn't listed, it may not be plugged in.
The meter just below will light up when you speak, so you can make sure you have the right source selected.
Microphone Connection
Verify your microphone is plugged in securely.
Analog
Make sure the microphone is plugged into the Pink audio port.
Digital
USB ports may have more or less power, and sometimes some USB ports don't have enough power. Try using a different USB port on your computer.
Check Headset Mute
Some headsets have a mute button. Make sure your microphone is not muted by pressing it one time.
There is usually a small light next to a mute button; if the light is on, your microphone is muted!
Check Input Volume on Computer
The volume set on your mic may be set low, it's good to check the settings to be sure it wasn't changed accidentally.
Windows
Using your right mouse button, Right click on the speaker in your System Tray, and select Open Sound settings.
Under Input, select Device properties.
Make sure Disable is not checked, and make sure the volume is at a reasonable volume.
A volume between 50 and 75 is usually appropriate.
Apple macOS
Open the Apple Menu, then select System Preferences.
Select Sound.
Select the Input tab at top, and make sure the Input volume is at a reasonable volume.
A volume between 50 and 75 is usually appropriate.
Check Mute in Webex
Webex has a built-in mute feature you can press if you happen to cough, or have other unwelcome noise happen that you don't want your colleagues to hear. Sometimes this can be set accidentally, so it's best to check it first.
Unmuted
Make sure the microphone in the circle at the bottom is not filled in at the bottom.
Muted
The microphone at the bottom will be filled in red when you are muted.
3. I Can't Hear Anybody, but They Can Hear Me
If you're seeing in text chat that you can be heard, but you can't hear anyone else, either your sound is muted, turned down too low, or the wrong speaker output is selected in Webex.
Check Audio Source in Webex
Since you can have multiple speakers outputs, it's important to tell Webex which device you are actually using.
While on a conference, select the Audio menu, then select Speaker, Microphone and Camera.
Make sure the proper Speaker is selected. If your speaker or sound device isn't listed, then make sure it is connected and on.
Press the Test button to the right to hear a chime to make sure you have the proper speakers selected.
Check Volume in the Operating System
You can adjust the volume on your computer, and sometimes this gets set too low or muted by mistake.
Windows
Select the speaker near the clock in your System Tray, usually in the bottom-right corner of your screen. You are able to move the slider back and forth to increase and decrease the volume.
Apple macOS
Select the Speaker on the top-right of your Menu bar. You can use the slider to adjust the volume.
4. I Hear an Echo, Static or Audio Sounds Bad
If your colleagues mention your audio quality is poor, or the audio you hear sounds bad, there are a few things you can check.
Use a Headset If possible, use a headset. Because your mic will pick up whatever is playing from your speakers, including your colleagues and your voice, it can cause a feedback loop. If possible, switch to using a headset and mic, so your mic won't pick up the sounds playing.
Turn Off Other Sources of Audio on Your Computer Some audio devices don't 'mix' audio well, and can degrade the quality of everything. Turn off any videos, music, or other audio you may be listening to while on the conference.
Replug Devices
Analog Devices
Analog audio devices connect using a minijack. Both the jack and the port on the computer can end up with little bits of dust which can cause audio to crackle, have static, or drop out. The simple fix is to unplug and replug the device, this removes the dust and tends to fix the problem.
USB Devices
USB Devices aren't as susceptible to dust, but because of how modern computers work, there could be not enough power on certain USB ports to power the device. Switch to a different USB port on your computer and try again.
Close Other Programs If the audio quality is poor, it's possible your computer doesn't have enough power to encode the audio quickly enough because other programs are running in the background. Close the other programs you're not using on your computer.
Reboot Your Computer If you're unable to find any programs to close, or if there's updates waiting to apply on your computer, it's possible this, too, could cause audio problems. Rebooting your computer can solve these problems.
Dedicated Audio Troubleshooting Guide We offer a separate, dedicated guide that will help you check a number of other options with the audio on your computer that may help further.
5. I Can't Fix My Sound, How Do I Connect by Phone?
If all else fails, and you need to be on a conference, Webex provides an option to switch to using any telephone for your audio, allowing you to follow along and get work done, so you can troubleshoot the problem with your computer's audio later.
If you do not have a mic, this also allows you to be heard till you can pick one up!
While on a conference, select the Audio menu, then select Audio Connection.
Next to Call in, select View.
You'll be given a Phone Number, Access Code, and Attendee ID.
Call the phone number listed.
Enter the access code when asked.
Enter the attendee ID when asked.
You can now hear and be heard over your phone, while still seeing the presentation on your computer screen.
