If your ARZOPA 32-inch 4K monitor has a clear picture but no sound, the speakers may not be broken. In many cases, Windows or the connected console is sending audio to the wrong device. The monitor may also be muted, connected through an adapter that doesn’t carry sound, or missing the right graphics audio driver.

This guide covers the main fixes for an ARZOPA monitor with no sound on Windows, macOS, PlayStation 5, Xbox Series X/S, and Nintendo Switch. Start with the basic checks first. Driver repairs and factory resets should come later, not at the beginning.

Why Are the ARZOPA Monitor Speakers Not Working?

Why Are the ARZOPA Monitor Speakers Not Working

Audio usually reaches a monitor through the same HDMI or DisplayPort cable that carries the picture. The source device sends the sound, the cable carries it, and the monitor plays it through its speakers. If one part of that chain is wrong, you may still see a perfect 4K image while hearing nothing.

The most common causes are:

  • The exact ARZOPA model doesn’t have built-in speakers
  • The monitor is muted in its on-screen menu
  • Windows selected headphones, Bluetooth audio, or another display
  • The browser, game, or media player is muted
  • The HDMI or DisplayPort cable has a poor connection
  • An adapter, USB-C dock, splitter, or KVM blocks audio
  • The monitor audio device is disabled in Windows
  • NVIDIA, AMD, or Intel display audio drivers are missing
  • A console is sending sound to a headset instead of HDMI
  • The monitor has a saved setting or hardware fault

One detail causes a lot of confusion. A monitor can have a 3.5 mm audio-out port without having built-in speakers. That port may only pass sound to external speakers or headphones, so checking the exact model comes first.

How to Fix ARZOPA 32-Inch 4K Monitor Sound?

Test the sound after every fix. This helps you find the real cause instead of changing several settings at once and not knowing what worked.

Use this order:

  • Confirm that your exact ARZOPA model has built-in speakers.
  • Raise the monitor’s internal volume and remove mute.
  • Select the ARZOPA display as your audio output.
  • Check the application volume mixer.
  • Reconnect or replace the HDMI or DisplayPort cable.
  • Enable or reinstall the graphics display audio driver.
  • Test the monitor with another device.

1. Confirm Your ARZOPA Model Has Built-In Speakers

Before changing drivers or buying another cable, check the full model number. ARZOPA sells different displays, and not every model has the same audio hardware. Even two monitors with a similar size and resolution can have different speaker features.

Look at the label on the back of the monitor. You can also check the original box, receipt, online order page, or product manual. The 32-inch 4K model may be listed as the ARZOPA M3RC, though product names and revisions can vary by seller or region.

Once you have the model number, check whether the specifications clearly say built-in speakers. Don’t assume a headphone symbol or 3.5 mm port confirms internal speakers. That port may only send audio out to another device.

If the monitor has no built-in speakers, connect external speakers or headphones to the monitor’s audio-out port. You can also connect them directly to the PC or console. In that case, there is nothing wrong with the monitor. It simply isn’t designed to play sound by itself.

2. Unmute the Monitor and Raise Its Internal Volume

Your computer volume and monitor volume are separate. Windows can be set to 100 percent while the ARZOPA monitor itself is muted or set very low. This happens more often than people expect, especially after changing a picture profile or resetting other display settings.

Use the monitor buttons or joystick to open the on-screen display menu. The control is normally under the bottom or rear edge of the monitor. Look for a section named Audio, Volume, Sound, or something similar.

Make sure mute is turned off. Raise the monitor volume to a clear testing level, around the middle or higher. You don’t need to leave it that loud, it just makes the test easier.

Play a video you know has working sound. A system notification or local music file is also fine. Avoid testing only one website because the browser tab itself may be muted.

If you can’t find any audio or volume option in the ARZOPA menu, check the manual again. A missing audio menu may mean your exact revision doesn’t include built-in speakers.

3. Select the ARZOPA Monitor as the Windows Audio Output

Windows often keeps using the last audio device you selected. You may connect the ARZOPA monitor, get a picture right away, and still have sound going to Bluetooth headphones, a controller, motherboard speakers, or another display.

On Windows 11:

  • Right-click the speaker icon in the taskbar.
  • Open Sound settings.
  • Find the Output section.
  • Select the ARZOPA monitor or display audio device.
  • Use the test option or play a video.

On Windows 10, open Settings > System > Sound and choose the correct output from the drop-down menu.

The device name may not say ARZOPA. It could appear as:

  • ARZOPA M3RC
  • Digital Audio
  • NVIDIA High Definition Audio
  • AMD High Definition Audio Device
  • Intel Display Audio
  • The name of your connected display

Choose each likely display output and test it. If sound starts, set that device as the default.

You can also check the older Sound Control Panel. Search Windows for Change system sounds, then open the Playback tab. Right-click the monitor audio device and choose Set as Default Device.

Here’s where it gets tricky. If the monitor doesn’t appear anywhere in the output list, the problem is more likely related to the cable, display connection, disabled device, or graphics audio driver. Move on to the later fixes instead of repeatedly changing the volume.

4. Check the Windows Volume Mixer and Application Output

Sometimes Windows sends normal system sound to the monitor, but one app stays silent. Browsers, games, media players, Discord, and other programs can have their own volume and output device settings.

Start playing audio inside the app that has no sound. Then right-click the Windows speaker icon and open Volume mixer. The application usually needs to be running and playing sound before it appears in the list.

Check the following:

  • The app isn’t muted
  • Its volume slider is high enough
  • Its output device is set to Default or the ARZOPA monitor
  • The browser tab isn’t muted
  • The game isn’t set to headphones or another audio device
  • A media player hasn’t saved an old HDMI output

If an app has the wrong output selected, change it to Default first. This lets it follow the main Windows output device. Restart the app after changing the setting because some games only detect audio devices when they open.

You can reset all application sound settings from the Volume Mixer if several programs are routed incorrectly. This is useful after disconnecting headphones or changing graphics cards, but it may also reset custom app volumes.

5. Reconnect or Replace the HDMI or DisplayPort Cable

A cable can carry a stable picture while audio detection still fails. It sounds strange, but video and audio are handled as separate parts of the same connection. A loose plug, damaged cable, or bad port may affect one more than the other.

Turn off the monitor and connected device. Remove the HDMI or DisplayPort cable from both ends, then connect it again firmly. Turn the monitor on first, followed by the computer or console.

Try another port if available. For example, move from HDMI 1 to HDMI 2. After switching ports, open the monitor input menu and make sure the correct source is selected.

A second cable is one of the best tests you can do. Use a known working HDMI or DisplayPort cable rather than buying an expensive cable right away. Price doesn’t guarantee that a cable will fix the issue.

Desktop PC users should check where the cable is connected. If your computer has a separate NVIDIA or AMD graphics card, connect the monitor to the graphics card ports. Don’t connect it to the motherboard video port unless the system is meant to use integrated graphics.

Once the cable is reconnected, open Windows Sound settings again. The monitor audio device may disappear when disconnected and return after Windows detects the new display connection.

6. Remove HDMI Adapters, Docks, KVM Switches and Splitters

Extra accessories make troubleshooting harder. Some USB-C docks, HDMI splitters, KVM switches, capture devices, and adapters pass video but handle audio poorly. Others create their own sound device that must be selected separately.

Connect the source device straight to the ARZOPA monitor for one test. Remove every adapter between them. If you normally use a laptop dock, connect the laptop directly through HDMI or USB-C video output where supported.

HDMI-to-DVI adapters need special attention. DVI connections often don’t carry sound, even when an adapter gives you a working picture. The same issue can happen with some older DisplayPort and VGA converters.

If direct audio works, the monitor is probably fine. Add each accessory back one at a time until the sound stops. That identifies the device causing the problem.

A USB-C dock may also need a driver or firmware update. Check its sound output in Windows because the dock can appear as a separate USB audio device. Don’t replace the monitor before ruling out the accessory in the middle.

7. Enable the Display Audio Device in Windows

Windows may detect the monitor but keep its audio device disabled. This can happen after changing graphics drivers, connecting several displays, or manually disabling unused playback devices.

Open the Sound Control Panel and select the Playback tab. Right-click an empty area inside the device list, then enable:

  • Show Disabled Devices
  • Show Disconnected Devices

If the ARZOPA monitor or digital display audio appears greyed out, right-click it and choose Enable. Set it as the default device and test the sound.

Next, open Device Manager:

  • Right-click the Start button.
  • Select Device Manager.
  • Expand Audio inputs and outputs.
  • Expand Sound, video and game controllers.
  • Look for the monitor or graphics display audio device.

Common names include NVIDIA High Definition Audio, AMD High Definition Audio Device, and Intel Display Audio. A yellow warning icon usually means the driver isn’t working properly.

If the device is missing, click Action > Scan for hardware changes. You can also disconnect and reconnect the HDMI or DisplayPort cable while Device Manager is open. Windows may detect the audio device again.

Be careful not to disable random sound devices while testing. Note their names first. Your motherboard audio, USB headset, and graphics audio can all appear in the same list.

8. Update or Reinstall the GPU Audio Driver

Monitor sound over HDMI or DisplayPort usually comes from the graphics hardware. This means updating only the Realtek motherboard driver may not fix anything. You need the display audio component included with the NVIDIA, AMD, or Intel graphics package.

Start by downloading the correct graphics driver from your GPU maker. Install the normal stable version for your Windows system.

For NVIDIA cards, make sure HD Audio Driver is selected during installation. It may appear as an optional component in the custom installation screen. If that part is unchecked, the monitor can show video without appearing as an audio output.

AMD users should install the full Adrenalin graphics package. Intel users should install the correct graphics driver for their processor or graphics card. Both normally include display audio support.

Restart the computer after installing the driver. Keep the ARZOPA monitor connected during the restart, then check Windows Sound settings again.

If a normal update doesn’t help, reinstall the graphics driver. Use the installer’s clean-install option if one is provided. Don’t use random driver download websites, since incorrect packages can create more problems.

Windows Update may also offer display audio drivers under optional updates. It’s worth checking, but the official graphics maker’s package is usually the better starting point.

9. Correct Audio Settings on PS5, Xbox or Nintendo Switch

Console audio can be routed to a headset, controller, or unsupported output format. The monitor may be working normally while the console sends sound somewhere else.

PlayStation 5

Open Settings > Sound > Audio Output. Check that the output device is set to the HDMI display or TV instead of a headset. If headphones are connected to the controller, disconnect them during the test.

Review the HDMI device type and audio format. If another format gives no sound, try Linear PCM. This is a useful test because some monitor setups handle basic PCM audio more reliably than other formats.

Restart the PS5 after making the change. Then open a game or app with known working audio.

Xbox Series X and Series S

Open Settings > General > Volume & audio output. Under speaker audio, make sure the output is set to HDMI. Disconnect any headset for the first test because Xbox may route game sound to it.

Try a simple stereo or uncompressed output option if another format isn’t working. Menu names can change with console updates, so focus on the HDMI speaker output section.

Restart the Xbox and monitor after changing the setting. If there is still no sound, test another HDMI cable or another monitor port.

Nintendo Switch

Make sure the Switch is seated properly inside its dock. Connect the dock directly to the ARZOPA monitor through HDMI, without a splitter or capture card.

Remove headphones from the Switch and monitor. Turn off the console, dock, and monitor, then reconnect everything. Start the monitor first, then wake the Switch.

If sound works in handheld mode but not through the dock, test another HDMI cable and another TV or monitor. That helps separate a dock issue from an ARZOPA speaker problem.

10. Power-Cycle and Factory Reset the ARZOPA Monitor

A complete power cycle can clear a temporary audio or input detection problem. Simply pressing the monitor power button isn’t always enough because some power remains inside the device.

Turn the monitor off and unplug its power cable. Remove the HDMI or DisplayPort cable too. Leave it disconnected for a short time, then reconnect the power cable first. Connect the video cable afterward and turn everything back on.

Test the sound before doing a factory reset. Power cycling doesn’t remove your picture settings, so it’s the safer step.

If sound is still missing, open the ARZOPA on-screen display and find Reset, Factory Reset, or Reset All. Take photos of your brightness, color, refresh-rate, and gaming settings first. A factory reset may remove those custom values.

Reset the monitor, reconnect the source device, and set the audio output again. The reset can clear a saved mute setting or input profile, but it won’t repair damaged physical speakers.

How to Tell if the ARZOPA Speakers Have a Hardware Problem?

Before deciding the monitor has failed, test it with another source device and another cable. This is the easiest way to separate a monitor fault from a computer, console, or connection issue.

Test Result Likely Meaning
Sound works with another computer or console The original source device has a setting or driver problem
Headphones work from the monitor but speakers don’t The audio signal arrives, but the internal speakers or speaker setting may have a problem
Neither speakers nor audio-out works The monitor may not be receiving audio, or it may have an internal fault
The monitor never appears as an audio device Check the cable, adapter, graphics port, and display audio driver
Sound cuts out when the cable moves The cable or connection port may be damaged
No sound from any device after a reset A monitor hardware problem becomes more likely

If possible, connect a laptop, game console, or streaming device directly to the monitor. Use a different HDMI cable and avoid adapters during the test. If every source gives the same no-sound result, and the exact model does have speakers, the monitor may need service.

Don’t open the monitor case yourself. Internal monitor parts can hold dangerous electrical charge even after the device is unplugged. Use warranty support or a trained repair technician instead.

What to Do if the Monitor Still Has No Sound?

When none of the fixes work, gather the main details before contacting ARZOPA or the retailer. A clear support request can save several messages back and forth.

Collect:

  • Full monitor model number
  • Serial number
  • Purchase date
  • Store or website where you bought it
  • Connected computer or console
  • HDMI or DisplayPort connection type
  • Operating system version
  • Graphics card model
  • Results from another cable
  • Results from another source device
  • Whether the monitor appears in audio settings
  • Whether headphones work from the monitor
  • A short video showing the issue

Explain the problem in simple terms. For example, say that the monitor shows video, its internal volume is raised, and no sound works from two different HDMI devices. That gives support a much clearer picture than only saying “speakers not working.”

Warranty approval depends on the seller, purchase date, product condition, and local terms. Keep the receipt and original order details ready. Don’t promise yourself a replacement until support checks the case.

How to Prevent ARZOPA Monitor Audio Problems?

Monitor audio is more reliable when you keep the setup simple. A direct cable connection, one default audio device, and stable graphics drivers remove many common failure points. Problems often return after swapping displays, connecting Bluetooth headphones, or adding a new dock.

A few habits can help:

  • Connect the monitor before starting the computer
  • Keep the ARZOPA display selected as the default output
  • Avoid unnecessary HDMI adapters and splitters
  • Use a cable that has already passed an audio test
  • Install stable graphics driver updates
  • Check monitor volume after loading a new picture profile
  • Test docks and KVM switches one at a time
  • Label cables that you know work correctly
  • Recheck console audio routing after using a headset

Final Thoughts

When an ARZOPA 32-inch 4K monitor has no sound, don’t assume the speakers are damaged. First confirm that the exact model has built-in speakers, then check the monitor volume and audio output device. After that, test the cable, remove adapters, and repair the graphics display audio driver.

A hardware fault becomes more likely only when the monitor fails with different source devices and known working cables. Until then, the problem is usually somewhere in the audio routing or connection. Comment with the exact ARZOPA model and tell us whether it appears in your Windows or console audio output list.
