Troubleshoot Skype Audio Not Working

Authored by: Support.com Tech Pro Team

1. Introduction

When you connect to a Skype call and others claim they can't hear you, or there's something very wrong with someone's audio, where do you start? Audio issues can be frustrating, especially if Skype is being used in a professional setting. Some of the most commonly reported Skype audio issues involve:

  • Being able to hear others, but others cannot hear you
  • Not being able to hear others, but others can hear you
  • Bad echo or overall poor audio quality

If you're suffering from any of the audio issues outlined above, read on. This guide will help you check your device and Skype settings to make sure all your calls go as smoothly as possible.

2. Check the Skype Service Status Page

The first thing you should do is check the Skype Service Status page. On the status page you can check to see if there are any outages or service interruptions occurring. If there is an issue, simply wait for service to return or contact Skype's customer service.

3. I Can Hear Others, but They Can't Hear Me

If you've got a microphone that's built-in or attached to your computer and it isn't picking up your voice, it may not be properly connected or its settings may not be configured correctly. Let's check the following to be sure that others are able to hear you on Skype.

Make sure the microphone is connected and not physically muted

When using external devices for your audio input, such as a headset, or USB microphone, make sure they are properly connected to your computer, are powered on and their audio levels are high enough to hear.

  1. Let's make sure the external audio devices are connected correctly to your computer first:

  3. Your microphone should plugged into the Pink audio port and your headphone or speaker into the Green one.

  2. In most cases, USB ports output power to drive the devices we've plugged in. Sometimes certain USB ports don't have enough power to properly drive the device we've connected. Make sure the USB cable has been fully connected/seated. If this doesn't have an effect, try using a different USB port on your computer.

  1. If you're using wireless devices, such as Bluetooth, make sure they're battery is charged, turned on and connected to the computer.
  2. If you're using a headset check whether or not it comes with its own little remote control. These often hang from the cords and have multiple marked buttons on them. With those buttons you can make sure the audio levels are where you want them to be. If there's a solid or flashing red light, it may mean the microphone is muted locally. Pushing the button should unmute it.

Check the microphone's volume on your computer

There's a possibility that your microphone is working just fine, but the volume of your microphone may be set too low, causing others to be unable to hear you. Check the volume of your microphone (sometimes referred to on your computer as the recording or input device) to be sure it is at a level others can hear.

Make sure you aren't muted in Skype

Skype 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 anyone else to hear. Sometimes this can be set accidentally, so it's best to check it first.

Granting Permissions on Apple macOS

Starting with macOS 10.14 Mojave security and privacy have been increased on Mac computers so that when you install certain apps, you will be asked to allow some permissions to be able to use all their features.

If you inadvertently "don't allow" access to your computer's services or devices to any of these apps at the time of installation, you can still change these settings later on if you notice certain functions to not work in these apps. Here's what to do:

  1. Open the Apple Menu and select System Preferences.
Apple Menu with System Preferences highlighted.
  1. Go to Security & Privacy.

  1. Click the padlock at the bottom left of the Security & Privacy window.

  1. The items you need to change permissions to for telecommunications apps are:
  2. Camera – Allows others to see you through your camera,
  3. Microphone – Allows others to hear you when you speak into your microphone,
  4. Screen Recording – Allows you to show what's on your screen,
  5. Files and Folders – Allows you to send and receive files, as well as record and save conversations or meetings onto your computer,
  6. Accessibility – Allows someone else to control your computer remotely while in a meeting.
  7. Some items are only available in macOS 10.15 Catalina or later. The items you need to change permissions to may be different for each app.
  8. You will be asked if you wish to restart the app. If you need to set more permissions, choose Later.
  9. Repeat the same process for each item you need to change permissions to.
  10. Once you've set all the necessary permissions, quit the app and restart it.

Giving Permission to Skype on Android

  1. Navigate to your Android device's Settings.
Android Settings
  1. Tap Applications then Application Manager.
Applications and application manager selection

4. 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 source may be selected in Skype. Let's go through and make sure everything is connected and correct.

Make sure the right speaker is selected

  1. With Skype open, select your profile picture. This will open a menu.

Check the volume levels

Many devices come with their own knobs and buttons to adjust the volume, but your operating system also has the ability to control its own volume. It's easily forgotten and overlooked. Make sure your sound hasn't been muted or turned too low by your Operating System. 

Windows

Check Mute and Volume Levels in Windows

  1. Right-click the speaker icon in the taskbar and select Open Volume Mixer.

Make sure the right speakers are being used by your computer

Have you hooked up your PC to your television? Use Airplay to stream movies? Well, you might have the wrong speaker selected and all the sound you want to hear it being blasted somewhere else in your house. Even just connecting a new monitor might switch your speaker selection. Let's check it here.

If all else fails, reboot

If none of the suggestions have restored audio to your speakers or headphones, reboot your computer and try again. This may seem like a useless step, but sometimes the audio services on a computer can fail. Rebooting can restart those services and potentially resolve the issue you're experiencing.

If you're still experiencing problems after a reboot, the speakers or headphones you're using may be malfunctioning. Try a different device, or reach out to the manufacturer for further assistance.

5. I Hear an Echo, Static or Audio Sounds Bad

If you hear audio echo or audio feedback during a call, this can be caused by:

  • One of the participants is using external speakers that their microphone is picking up, or is too close to.
  • There may be multiple participants in the same room using their own personal computers/devices.

Keep microphones away from external speakers that are in-use

If any participants are using external speakers to listen to the call, their microphone may be picking up what's being played back, causing other attendees to hear an echo. If a microphone is too close to external speakers, this can cause loud audio feedback. Always recommend that attendees use headphones or a headset with a built-in microphone to minimize the chances of this being an issue.

If multiple meeting participants are in close proximity to each other

Similar to the suggestion above, always suggest that participants use their own headphones or headsets to avoid situations where one person's microphone picks up another.

If you're having problems with an echo

If any of the participants within a call are hearing an echo, it means that someone's microphone is picking up the audio that's being played back. In most cases, this can be avoided if participants who aren't speaking simply mute themselves if they aren't speaking. If you are the host/presenter you can:

  • Mute attendees one at a time to determine which one is causing the echo issue.
  • Mute all attendees and only unmute someone when they're asked to speak.
  • Have attendees mute themselves if they do not plan on speaking, or are just there to listen.

Additional sources that can potentially cause echo issues:

  • Speakers (such as TV or soundbar) that are too loud.
  • Microphone echo cancellation features that have failed (this is likely a device or performance issue).
  • A malfunctioning microphone.
