Question

lost all sound after installing a new SAMSUNG monitor

Answer 1

Hi Robin Eddy,

Thanks for posting your question. I understand that you lost all sound after connecting a new Samsung monitor.

Before going further, can you please confirm whether you’ve already tried the suggestions provided by Q&A Assist?

If you’ve already tried those steps and the issue persists, please try the disable the monitor as an audio device:

Sometimes Windows keeps routing audio to the monitor even if it doesn’t have usable speakers.

1. Press “Windows + R”, type “mmsys.cpl”, and press Enter.
2. On the “Playback” tab, look for your Samsung monitor or any device labeled “HDMI” or “Display Audio”.
3. Right‑click that device and select “Disable”.
4. Make sure your actual speakers or headphones are set as “Default Device”, then click “OK” and test the sound again.

Please share a screenshot of the "Playback" tab of the sound options.

(Do this with the monitor connected.)

1. Press "Windows + R", type mmsys.cpl and press Enter;
2. Select the "Playback" tab and take the screenshot.

Use the shortcut "Windows + Shift + S" to use the screenshot tool.

Also. What is the manufacturer and model of your computer?

If you prefer, you can share a screenshot of your system information.

• Press "Windows + R", type msinfo32 and press Enter.

Maximize the window and use the shortcut "Windows + Shift + S" to use the screenshot tool.

Looking forward to your reply.

Installing the new Samsung monitor likely changed the default audio output to the monitor (which may have poor speakers or none at all) or affected the audio driver.

Try these steps in order on Windows 11:

1. Set the correct output device
   1. Select Start > Settings > System > Sound.
   2. Under Output, select the speakers or headphones actually used (for example, PC speakers, external speakers, or headset). Selecting it sets it as the default.
   3. If the monitor is selected as the output and it has no speakers, change it to the correct device.
2. Check sound settings and mute state
   1. Right-click the Speakers icon on the taskbar and select Open Volume mixer.
   2. Make sure none of the volume sliders are muted (no red circle with a line). If muted, click to unmute.
   3. In Settings > System > Sound, select the chosen audio device, then Device properties, and ensure the device is not disabled.
3. Update or reinstall audio drivers
   1. In the taskbar search box, type device manager and open it.
   2. Expand Sound, video and game controllers.
   3. Right-click the PC’s main audio device (for example, Realtek, Intel, or similar) and select Update driver > Search automatically for drivers. Complete the update if one is found.
   4. If the problem persists, right-click the same device, select Uninstall device, check Attempt to remove the driver for this device (or Delete the driver software for this device), and select Uninstall.
   5. Restart the PC so Windows reinstalls the audio driver automatically.
4. Install Windows Updates
   1. Select Start > Settings > Windows Update.
   2. Select Check for updates.
   3. Install all available updates, including any optional driver updates, then restart and test sound again.

If the monitor is connected by HDMI/DisplayPort and the PC keeps switching audio to it, repeat step 1 after each reconnect and ensure the preferred speakers are selected as the default output device.
