The built-in microphone on your HP Pavilion x360 14 Intel Core i5 1335U is not working in video calls – meeting participants cannot hear you in Teams or Zoom, or voice recording applications show no input signal. Windows microphone privacy settings or incorrect input device selection are the most common causes before a driver issue on the HP Pavilion x360 14.

This guide covers Windows microphone privacy, Sound input settings, and Realtek audio driver updates to restore microphone function on the HP Pavilion x360 14 Intel Core i5 1335U in Windows 11.

“HP Pavilion x360 14 microphone stopped working in Teams. Checked Settings and microphone access was turned off by privacy policy. Turned it on for Teams and microphone worked immediately.” – Norfadzilah, teacher from Pahang

Why Microphone Does Not Work on HP Pavilion x360 14

Windows 11 has a system-wide microphone privacy switch that controls whether applications can access the microphone hardware. After a Windows 11 update, this setting sometimes resets to off, causing all video call applications to show no microphone input. Additionally, if an external microphone was previously connected, Windows may have set the external device as the default input, and after unplugging it, no fallback to the built-in microphone occurs automatically without manual selection in Sound settings.

• Windows 11 microphone privacy switched off globally or per-application
• Wrong input device selected in Sound settings – external mic set as default, now unplugged
• HP Pavilion x360 14 F4 microphone mute keyboard shortcut active – microphone hardware muted
• Realtek audio driver missing or corrupted after Windows 11 update

Fix 1 – Enable Microphone Privacy Access

Go to Settings – Privacy and security – Microphone. Toggle Microphone access to On. Below, toggle Let apps access your microphone to On. Scroll down to find the specific video call application (Teams, Zoom, Google Meet) and toggle it to On individually. A Windows 11 update can reset per-application microphone permissions without warning. Enabling microphone access globally and per-application is the fastest fix for microphone not working in specific apps on the HP Pavilion x360 14.

Fix 2 – Set Default Microphone in Sound Settings

Go to Settings – System – Sound. Under Input, check the device listed as your microphone. Click the dropdown and select HP Pavilion Microphone Array or Realtek Microphone (the built-in dual-mic array). Click the arrow next to it and adjust the input volume to 80-100 percent. The mic icon shows the current input level – speak and verify the bar moves. If no built-in microphone appears in the list, the Realtek audio driver needs reinstallation.

Check F4 Microphone Mute Key

On the HP Pavilion x360 14, the F4 key has a microphone mute icon. Press F4 (or Fn+F4 depending on keyboard configuration) to toggle microphone mute. The keyboard may have an indicator LED showing the mute state. If the microphone was muted via F4, no amount of software configuration restores audio as the hardware itself is muted by the keyboard shortcut. Check and unmute via F4 before checking any software setting.

Fix 3 – Update Realtek Audio Driver from HP Support

Open HP Support Assistant and check for Realtek High Definition Audio driver updates. Install and restart. Updated Realtek audio drivers for the HP Pavilion x360 14 Intel Core i5 1335U include dual-microphone array configuration improvements that restore correct channel assignment for the left and right internal microphones. After driver update, re-test microphone input in Windows Sound settings before opening the video call application.

Fix 4 – Run Audio Troubleshooter

Go to Settings – System – Troubleshoot – Other troubleshooters. Find Recording Audio and click Run. The recording audio troubleshooter checks default microphone configuration, Realtek driver status, and Windows audio service state. It automatically resets incorrectly configured audio services and default device assignments. Run the troubleshooter after each fix to confirm the microphone input level registers correctly before testing in video call applications.
