Answer 1

Hi! Let me help you with this issue.

Please hover your mouse over the sound icon in the lower-right corner, then right-click it and select Troubleshoot Sound. Let the troubleshooter finish its task, then this should either resolve the problem or display an error message.

If that doesn't work, we need to remove the Audio driver from the Device Manager and restart the PC to reinstall it.

Here are the steps to completely remove a Device from your computer.

Step 1. Use the Windows key + X shortcut.

Step 2. Select Device Manager.

Step 3. Expand the entry Sound, Video, and Game Controllers. Right-click the problematic device, which is either Realtek Audio, or AMD High-definition Audio, or High-Definition Audio, depending on the audio device installed in your PC, and select Uninstall device.

Step 4. You need to check the option Delete the driver software for this device and then click the Uninstall button.

Step 5. Reboot the computer.

After the reboot, please see if the problem is fixed.

If that still does not work, please visit the support website of your laptop or desktop and then download and install the latest Audio driver, then restart the PC.

Use a step‑by‑step approach to isolate whether this is a Windows configuration issue or a driver/hardware problem.

1. Check basic sound settings
   • On the taskbar, select the Speakers icon.
   • Use the arrow to open the list of audio devices and make sure the correct Speakers/Headphones (Realtek/Intel/HP, etc.) device is selected as output.
   • Right‑click the Speakers icon > Open Volume mixer and verify that none of the sliders (system and apps) are muted and volumes are up.
   • Go to Start > Settings > System > Sound and under Output and Input, select the correct devices and check Device properties to ensure they are not disabled.
2. Verify physical connections and volume controls
   • Check that speakers/headphones are firmly plugged in and, if using 3.5mm jacks, that they are in the correct port (green for output, pink for mic on many systems).
   • Make sure any hardware volume/mute buttons on the laptop or headset are not set to mute and that power is on.
   • If using USB audio, try a different USB port and disconnect any headphones to test the internal speakers.
3. Run built‑in troubleshooters
   • For sound output: Start > Settings > System > Troubleshoot > Other troubleshooters > under Audio, select Run.
   • For microphone: use the Fix microphone problems guidance and test the mic under Settings > System > Sound > Input (use the test function if available).
4. Check microphone privacy settings
   • Windows 11: Start > Settings > Privacy & security > Microphone.
     • Turn Microphone access and Let apps access your microphone to On.
     • For specific apps (Teams, browser, etc.), ensure their toggles are On.
   • Windows 10: Start > Settings > Privacy > Microphone and enable Allow access to the microphone on this device, and enable the apps that need access.
5. Reinstall or update audio drivers Since the issue started after opening the laptop, drivers may have been affected or the device may be mis‑detected.
   • Open Device Manager (right‑click Start > Device Manager).
   • Expand Sound, video and game controllers.
   • For each audio device (e.g., Realtek, Intel, etc.):
     1. Right‑click > Uninstall device.
     2. Check Attempt to remove the driver for this device (or Delete the driver software for this device where shown) and select Uninstall.
   • Restart the PC; Windows will attempt to reinstall audio devices automatically.
   • If they reappear, in Device Manager right‑click the audio device > Update driver > Search automatically for drivers.
6. If devices are missing or still not working
   • If no audio input/output devices show in Settings > System > Sound or Device Manager, repeat the uninstall/restart steps and then in Device Manager use Scan for hardware changes on Sound, video and game controllers.
   • If still missing or non‑functional after driver reinstall, this may indicate a hardware issue (e.g., loose internal audio connection from unclipping the laptop). In that case, use HP diagnostics and consider reseating internal audio components or contacting HP support for hardware inspection.
7. Additional microphone‑specific checks
   • Ensure the correct input device is selected under Settings > System > Sound > Input.
   • Increase mic volume: open mic Device properties and adjust Levels (Windows 10) or use Input volume and Start test (Windows 11) to verify the mic is picking up sound.

If after these steps the devices show as “working properly” in diagnostics but there is still no sound in any app, the most likely causes are: incorrect default device selection, privacy settings blocking the mic, or a hardware connection issue introduced when the laptop was opened.
