Zoom meeting has no sound? This could be the reason

Video con­fer­ences have many ad­van­tages. On the one hand, they make it easy to com­mu­ni­cate no matter the location of the par­tic­i­pants - be it with friends, family members, customers, or col­leagues. On the other hand, a video con­fer­enc­ing program like Zoom makes it possible to organize large meetings and pre­sen­ta­tions online in a very flexible way. Pro­fes­sion­al­ism is par­tic­u­lar­ly important in this context. Common technical errors that occur time and again in virtual video con­fer­ences are dif­fi­cul­ties with sharing the screen in Zoom, changing the back­ground in Zoom, and problems with audio equipment.

There may be a number of reasons why other par­tic­i­pants cannot hear you or why no sound is coming from the Zoom meeting. Typical error sources include:

  • Other par­tic­i­pants have muted their mi­cro­phone, speakers, or head­phones.
  • Incorrect audio settings or recording devices have been selected.
  • Audio scripts are blocked by temporary data in the browser cache.
  • The computer’s audio output is muted.
  • Speakers built into the smart­phone have been disabled in the app.
  • The smart­phone’s volume or audio profile is in­cor­rect­ly set up.

Specify and test the Zoom audio settings

If you want to create a Zoom meeting or join a Zoom meeting as a par­tic­i­pant, it is advisable to know your way around Zoom’s audio settings, to set the mi­cro­phone and speakers/head­phones correctly, and to carry out an audio test if in doubt.

  • Step 1: Log in to your Zoom account by entering your user data in the Zoom client.
  • Step 2: Click on your profile picture and below that you should see the gear icon with “Settings”.
  • Step 3: Then go to “Audio” in the left sidebar.

Click on “Audio” in the “Settings” menu
  • Step 4: Here you will find a whole list of audio options. The important items are “Speakers”, “Mi­cro­phone”, “Au­to­mat­i­cal­ly join audio by computer when joining a meeting” and “Mute my mi­cro­phone when joining a meeting”.
  • Step 5: Under “Speakers”, you can perform an audio test and select the ap­pro­pri­ate speaker from the drop-down menu.

Test the function of your speakers and check whether the correct speaker is selected.
  • Step 6: Under “Mi­cro­phone”, you can test the audio input, select the mi­cro­phone from the drop-down menu, and enable automatic sound en­hance­ment.

Check the func­tion­al­i­ty of your mi­cro­phone.
  • Step 7: By checking the “Au­to­mat­i­cal­ly join audio by computer when joining a meeting” box, you instruct Zoom to au­to­mat­i­cal­ly connect to your computer audio during meetings.

Enable automatic audio con­nec­tion via computer to give Zoom access to your computer audio when you enter a meeting.
  • Step 8: With the “Au­to­mat­i­cal­ly join audio by computer when joining a meeting” option disabled, you will always receive a prompt to connect to audio before the meeting. In this prompt window, you can also perform an audio test and enable automatic con­nec­tion to computer audio.

With computer audio con­nec­tion disabled, Zoom will ask for speaker and mi­cro­phone access before you enter each meeting.
  • Step 9: If you attend a lot of meetings or regularly join meetings, you may want to re­con­sid­er the “Au­to­mat­i­cal­ly join audio by computer when joining a meeting” option to avoid ac­ci­den­tal­ly becoming the active speaker. However, this could be the cause of the Zoom audio not working so remember to turn the mi­cro­phone back on when needed.

Zoom: No sound – how to solve the problem

When it comes to small meetings con­sist­ing of two or three people, first ask the question:

  • Have the other par­tic­i­pants muted their own mi­cro­phones or speakers?

If they haven’t and you can’t hear or be heard in a Zoom meeting, you can assume that the problem is on your end. Here are a few possible solutions.

Using the desktop client (Windows/Mac)

Test audio playback and recording devices in a meeting

During a meeting, test your audio devices in the audio settings. To do this, go to the arrow next to the mi­cro­phone icon and click on “Audio Settings…” or “Test Speaker & Mi­cro­phone…”. Here you can test your speakers/head­phones and mi­cro­phone re­spec­tive­ly or change selected devices.

Clear browser cache

Too much temporary data in the browser cache can cause blocked audio scripts on Zoom in rare cases. To clear your browser cache, open the browser settings menu, and clear both the cache and the cookies.

Check the audio output from your computer

If the Zoom audio doesn’t seem to be working, it may also be due to the computer volume. Check if the volume on your computer is muted or too low. To do this, click the speaker icon in the bottom right corner of Windows 10. To open advanced settings, right-click on the speaker icon and then select “Open Volume mixer”.

Check that the volume is set correctly for Zoom meetings.

Note

With macOS, you can also find volume control options via the menu bar or System Pref­er­ences.

Using the mobile client (Android/iOS)

Check the speaker in the Zoom app

If there’s no sound in the Zoom meeting, check your built-in smart­phone speakers. Look to see if you can see an X next to the speaker icon. If so, activate the speakers using the buttons or by tapping the speaker icon.

Check the mi­cro­phone in the Zoom app

If the other par­tic­i­pants can’t hear you in the meeting, check your built-in mi­cro­phone. If you see that you’re muted, tap the mi­cro­phone icon to unmute yourself.

Check smart­phone audio settings

If you are having audio problems in a Zoom meeting on your smart­phone, it is often because the device’s volume is too low. Check the volume using the volume buttons on your smart­phone.

If you ha­bit­u­al­ly set your smart­phone to silent or vibrate, check the audio profile on Android or iOS to see if the sound is turned on.

Restart your smart­phone

As simple as it sounds, rebooting often helps solve audio problems. However, this is only an al­ter­na­tive if you don’t have important, time-limited meetings.
