Acer Monitor No Sound (8 Easy Fixes!)

Acer has a deep lineup of computer monitors for nearly every occasion. While Acer has built a highly trusted brand, like any highly produced product, their monitors can occasionally have some frustrating issues. One of the more common problems users report is their Acer monitor sound not working.

To fix the Acer monitor no sound problem, first confirm your Acer model supports audio. Then update audio source, adjust the monitor and PC volume settings, and enable loudness equalization. If the issue persists, check the audio cables, update the audio driver, and ensure BIOS audio onboard device is enabled.

There are 8 common troubleshooting steps you should try.

I strongly recommend you follow these steps in order.

We will start with the most common fixes and then work our way towards less common, more involved troubleshooting steps.

Step 1: Confirm Monitor Audio Output Compatibility

Ok – let’s get the obvious stuff out of the way first.

Not all Acer monitors have built-in speakers and/or support audio output functionality.

While this may seem obvious, it is also the most common explanation for your monitor sound not working.

So before you do anything else, double check whether or not your specific model has built-in speakers and/or supports audio output functionality!

The easiest way to confirm this, is to first identify your monitor model number. This is usually located on a sticker on the back or bottom of the monitor.

Next, enter the Acer model number into the Acer monitor manual lookup.

Once the Owner’s Manual or Specification Summary Document has been downloaded, locate the product specifications section. Here, under Audio OutputIntegrated Speakers, etc. determine if your specific monitor supports speakers.

It is important to note that an Acer display that supports “audio output” is NOT the same thing as having built-in speak capabilities.

Supporting audio output simply indicates that you can plug headphones or external speakers into your monitor directly.

Ok – so now you’ve confirmed whether or not your monitor has built-in speakers or supports audio output. Maybe it does both? Continue on to step 2.

Step 2: Update Default Audio Source

It is also incredibly common to experience this issue due to having the incorrect audio source selected on your PC.

Therefore, it is critically important to set the audio output of your PC to the specific display or audio device you are using.

The specific settings will differ slightly depending on the operating system you are using.

For Windows 10, and the vast majority of Windows operating systems, first select select volume from the application tray in the bottom right corner of your screen.

This may appear as a standalone volume icon as shown below, or you may need to click the application up arrow icon and select it there.

Update Windows audio output

Here you will find each of the available audio sources. In my case, I have an external speaker attached to my monitor and so this is what I have selected.

For Acer displays with built-in speakers, you can select the monitor itself as the playback device. Similarly if you are using external headphones, you will be able to select them here.

Step 3: Adjust Volume On Monitor

Another quick and simple troubleshooting step to cross off the list early is to check your volume levels.

It’s possible you are encountering this issue simply because the monitor has been set to mute or is set too low.

For the vast majority of monitors that support audio output, you can adjust the monitor volume level through the main menu button on the right side of the monitor.

Adjust Acer monitor volume levels

Make sure that the monitor volume is on and set high enough to hear.

If you are having trouble locating the volume controls, use the Acer monitor manual lookup for assistance. Additionally, if you are unable to gain access to the on screen display (OSD) to adjust the volume, be sure to unlock the OSD and try again.

Step 4: Inspect Volume Settings On PC

Similarly, you also need to make sure that you have the proper volume settings on your PC or primary operating device.

First, right click on the volume icon in the applications tray in the bottom right corner of your screen. Then select Open Sound Settings.

Under Sound Settings, make sure that the Master volume has not been accidently set to Mute and is at a reasonable level.

Next, right click on the volume icon again and this time select Open volume mixer.

Once again, make sure that the application you are attempting to use is not on mute and instead is set to an audible volume level.

An extremely common mistake that leads to your Acer monitor sound not working is not realizing that applications like Google Chrome for example, have their own distinct volume settings.

This steps applies regardless of whether you have a PC hooked up to your display or some other device.

Regardless of the device you are using, if it has its own volume settings, you need to ensure they are properly calibrated.

Step 5: Enable Loudness Equalization

I also suggest you enable Loudness Equalization.

With Loudness Equalization turned on, the volume of sounds that are being produces will become normalized and balanced.

This means that really loud sounds will be more quiet. But more importantly in this case, really quiet sounds will be boosted and become more amplified.

How To Enable Loudness Equalization

  1. First, type Control Panel into the Windows search field and select it from the pop up menu.
  2. Then, within the Control Panel locate and select Sound.
  3. Next, double click on the device through which you would like the audio to play through.
  4. Finally, under the Enhancements tab, enable Loudness Equalization and click OK.

Step 6: Check Audio Cables

You also need to carefully check all audio cable connections.

For Acer monitors with with built-in speaker capabilities, the audio is most often carried through the DisplayPort (DP) or HDMI cable directly.

HDMI and DisplayPort (DP) cable

In some cases, you may even have a VGA cable that has a connected but separate audio jack connection.

For monitors that do not have built-in speakers but do support audio output, there will be a separate audio jack cable for your device.

First and foremost, make sure the audio cable is plugged into the correct ports on your display and PC/device.

Also confirm that the connection with your specific cable is firm on both ends. Because these cables often carry both video and audio signals, even a slightly broken connection can result in sound issues, in addition to visual issues like screen flickering and no signal errors.

Next, make sure there are no issues or obstructions with the audio cable itself. Check for any signs of visible damage.

Finally, try using a different audio cable than you are currently using.

For example, if you are specifically encountering this problem while using an HDMI cable, try swapping out the HDMI for a DP, or VGA cable and vice versa.

If using a different audio cable solves the issue, a faulty audio cable was likely the culprit.

Step 7: Update Computer Applications And Audio Driver

If none of the above fixes have worked, your PC applications or audio driver may be out of date.

How To Update Your Computer Applications (Windows 10)

Many application publishers will provide periodic updates to their apps. Often times these updates include new features or provide fixes to various app issues.

You can use your Microsoft Store on Windows to automatically install app updates.

  1. First select Start, and click on the Microsoft Store.
  2. Once you are in the Microsoft Store, select the account menu and then select Settings.
  3. Under App updates, set Update apps automatically to OnHere you can see my default settings are set to update apps automatically already. This may also be the case from some of you. For others, you will need to use the toggle button to turn this setting on.

Depending on your version of Windows, these steps may slightly vary. Check out the official Windows support page to learn how to update your apps across Windows versions.

How to Update And Reinstall Your Audio Driver (Windows 10 / 11)

Sometimes the audio driver is specifically to blame. To test this, first try to update the audio device driver directly.

Head over to the search box and this time enter Device Manager. Under Sound, video and game controllers right-click on the name of your audio device, and select Update driver.

Update audio device driver

First, select Search automatically for updated driver software and wait for your audio driver to be updated. If this doesn’t work, select Search for update drivers on Windows Update instead.

If this does not fix your problem, try uninstalling the sound driver by right-clicking and selecting Uninstall.

Then simply Restart your computer – Windows will automatically attempt to reinstall the audio driver during startup.

If your driver does not automatically reinstall, or if you do not see your specific audio device driver within the device manager to start with, you will need to download it.

Step 8: Ensure BIOS Audio Onboard Device Is Enabled

If all else fails, it is possible that your audio has been accidently disabled in the BIOS.

While uncommon, users who have purchased a used PC have sometimes reported their onboard audio settings being tampered with.

To check this, you will need to restart your PC and determine the relevant keyboard key during startup that will take you to the BIOS.

Most often the BIOS redirect key will be displayed on screen. However, if you are unsure, search for your PC name and model number and look it up in the corresponding user manual.

In the BIOS, locate Onboard Devices and make sure Audio is enabled.
