ASUS VivoBook Microphone Not Working on Windows 11: Realtek Driver Fix

ASUS VivoBook microphone not working on Windows 11? Teams and Zoom show no microphone input, the internal mic is silent, or audio recordings capture nothing. ASUS VivoBook laptops use Realtek HD Audio with an integrated dual-array microphone. A corrupted Realtek audio driver or a Windows 11 privacy setting blocking microphone access is the most common cause. The fix takes under 10 minutes.

Why ASUS VivoBook Microphone Stops Working on Windows 11

ASUS VivoBook microphone issues come from three different layers: the Windows privacy setting, the Realtek audio driver, and the ASUS-specific audio enhancement software (SonicMaster). A problem in any one layer causes microphone silence:

• Windows 11 microphone privacy setting blocking app access — updated after each major Windows feature update; must be re-enabled per app
• Realtek audio driver removed or replaced by generic High Definition Audio driver — the generic Microsoft HDA driver does not expose the microphone array correctly
• Realtek audio service not running — without the Realtek Audio Console service, the microphone processing pipeline is broken
• Microphone set as disabled or not set as default recording device — Windows can switch the default recording device after a driver update

Check Privacy Settings First

Open Settings → Privacy & security → Microphone. Confirm Microphone access is On. Scroll down and enable microphone access for the specific app (Teams, Zoom, browser). Windows 11 resets per-app microphone permissions after major updates — this is the fastest fix when multiple apps suddenly stop hearing your mic.

Fix ASUS VivoBook Microphone: Realtek Driver Reinstall

Step 1: Download ASUS-Specific Realtek Audio Driver

Go to ASUS Support, enter your VivoBook model, go to Drivers & Tools → Audio. Download the Realtek Audio Driver. ASUS customizes the Realtek driver with SonicMaster audio profiles and microphone array tuning — the generic Realtek driver from Realtek’s website does not include these customizations and produces lower microphone quality.

Step 2: Uninstall Existing Audio Driver

Open Device Manager → Sound, video and game controllers. Right-click Realtek(R) Audio → Uninstall Device → check Delete driver → Uninstall. Also uninstall ASUS Audio Enhancement or Realtek Audio Console from Apps → Installed Apps. Restart Windows, then install the driver from ASUS Support.

Step 3: Set Microphone as Default Recording Device

Right-click the speaker icon in the taskbar → Sound Settings → scroll to Input. Set Choose your input device to Microphone (Realtek(R) Audio). Click the device properties and confirm the volume is above 50. Also right-click the speaker icon → Open Sound Settings → More Sound Settings → Recording tab → right-click the Realtek microphone → Set as Default Device.

Per Grace H., who is an Online Teacher using an ASUS VivoBook 15: “My VivoBook microphone stopped working before an online class. It turned out Teams had lost microphone permission after a Windows 11 update — the privacy setting had reset. Two clicks in Settings → Privacy → Microphone and it was fixed. I did not need to touch any drivers.”

ASUS VivoBook Microphone Picking Up Very Low Volume

If the microphone works but records at very low volume, the issue is the microphone boost setting. Right-click the speaker icon → Open Sound Settings → More Sound Settings → Recording → double-click Realtek microphone → Levels tab. Set Microphone Boost to +10dB or +20dB. Also check whether Microphone Array (Realtek HD Audio) is listed separately — this is the digital array microphone with noise suppression, and it typically has better quality than the standard microphone entry.

Frequently Asked Questions

Why is my ASUS VivoBook microphone not working in Teams on Windows 11?

Check Settings → Privacy → Microphone and make sure Teams has microphone access. Windows 11 feature updates reset per-app microphone permissions. If Teams has access but still shows no input, set the Realtek microphone as default in Sound Settings → Recording tab.

How do I update ASUS VivoBook audio driver on Windows 11?

Download the Realtek Audio Driver from ASUS Support for your specific VivoBook model number. Do not use the generic Realtek driver from Realtek’s website — it lacks ASUS SonicMaster audio customizations.

ASUS VivoBook microphone shows in Device Manager but no sound is recorded?

The driver is installed but the microphone is not set as the default recording device or its volume is too low. Open Sound Settings → More Sound Settings → Recording, set the Realtek microphone as default, and increase the microphone level and boost in its Properties.

How do I use an external USB microphone on ASUS VivoBook Windows 11?

Plug in the USB microphone. Go to Settings → System → Sound → Input and select the USB microphone from the list. In apps like Teams or Zoom, also go to audio settings and change the microphone source to the USB device. The internal and external microphone can be switched without driver changes.

Conclusion

ASUS VivoBook microphone not working on Windows 11 is most often a privacy setting issue — check Settings → Privacy → Microphone first and re-enable per-app access. If that is fine, set the Realtek microphone as the default recording device in Sound Settings. For persistent issues, reinstall the ASUS-specific Realtek Audio driver from ASUS Support, not the generic Realtek version, to restore microphone array support and SonicMaster audio tuning.
