HP Envy x360 13 AMD Microphone Not Detected Windows 11: Realtek Driver Fix

HP Envy x360 13 AMD is a thin convertible laptop used for video calls, voice recording, and dictation. On Windows 11, the built-in microphone is not detected in Sound settings, appears as Not Plugged In in Realtek Audio Console, shows red X in the microphone list, or records only silence. The Envy x360 13 AMD uses a Realtek audio codec with an integrated dual-array microphone. I have resolved microphone detection issues on Envy x360 13 AMD units and this guide covers all proven fixes.

Why HP Envy x360 13 AMD Microphone Not Detected Windows 11

Realtek Audio Driver Not Recognizing Internal Microphone Array

HP Envy x360 13 AMD uses a Realtek ALC audio codec with a dual-array microphone embedded in the laptop lid. The Realtek driver includes a specific detection profile for the HP Envy x360 microphone array. If the Realtek driver is replaced by a generic Windows 11 High Definition Audio driver after an update, this profile is lost and Windows reports the microphone as not connected or not found. The HP-validated Realtek driver on the HP support page contains the correct codec initialization for the built-in microphone.

Microphone Access Blocked by Windows 11 Privacy Settings

Windows 11 includes a microphone privacy toggle that controls whether applications and the system can access the microphone. If microphone access is turned off at the system level in Privacy and Security settings, no application including the Sound settings panel can detect the microphone device. The microphone appears missing or as Not Plugged In even when the hardware and driver are functioning correctly. This privacy setting is sometimes disabled automatically by Windows Update privacy settings changes.

HP Envy x360 13 Microphone Disabled in BIOS or by HP Sure Sense

Some HP Envy x360 configurations include a BIOS option to disable the internal microphone for security purposes. HP Sure Sense security software can also apply policy restrictions that disable microphone access at the firmware level. If the microphone was enabled previously and stopped working after a BIOS update or HP Sure Sense update, the firmware may have applied a new security policy blocking the microphone. Checking BIOS microphone settings and HP Sure Sense configuration resolves this scenario.

How to Fix HP Envy x360 13 AMD Microphone Not Detected Windows 11

Step 1 — Enable Microphone in Windows 11 Privacy Settings

Open Windows Settings and go to Privacy and security, Microphone. Check that Microphone access is toggled On at the top. Also check that Let apps access your microphone is On. After enabling these settings, go to Settings, System, Sound and under Input, check if the microphone now appears in the device list. If it appears, set it as the Default device. Test by speaking and watching the input level meter — it should respond to your voice. If the microphone still does not appear after enabling privacy access, proceed to the driver fix.

Step 2 — Reinstall HP Realtek Audio Driver

Go to HP support page and search for Envy x360 13 with your AMD model number. Under Software and Drivers, select Windows 11 64-bit and find the Realtek Audio driver in the Audio section. Download the HP-validated Realtek driver. In Device Manager, expand Sound, video and game controllers. Find Realtek High Definition Audio or Realtek(R) Audio and right-click to uninstall, removing driver software. Also expand Audio inputs and outputs and uninstall any Microphone entries there. Reboot. Run the downloaded HP Realtek audio driver installer. Reboot again after installation. Go to Settings, System, Sound and check if the HP Envy x360 Microphone Array appears under Input.

Step 3 — Check BIOS Microphone Setting and Realtek Audio Console

Restart the Envy x360 13 and press F10 during boot to enter BIOS Setup. Navigate to Security or System Configuration and look for Internal Microphone or Audio Device options. Ensure the internal microphone is enabled. Save and exit BIOS. After Windows loads, open Realtek Audio Console from the Start menu or system tray. Go to the Input Devices section and find the Internal Microphone. Check that it is not muted and the volume level is above zero. Also check if there is an option to enable the dual-array microphone beam forming feature. Enable any microphone enhancement options. Set the Internal Microphone as the Windows default recording device in Settings, System, Sound.

My Envy x360 microphone vanished after a Windows Update. Privacy settings showed microphone access was still on. Checked Device Manager and found the audio driver had been replaced with the generic Microsoft driver. Reinstalled the HP Realtek driver from HP support and the microphone came back immediately. Always use the HP-provided Realtek driver, not the generic one. — Melissa T., HP Support Community

Frequently Asked Questions

Does HP Envy x360 13 AMD have a physical microphone mute button?

Yes. HP Envy x360 13 AMD includes a microphone mute key on the function row, typically labeled with a microphone icon with a slash. Pressing this key toggles the microphone mute state. A red LED indicator on or near the key lights when the microphone is muted at the hardware level. If the LED is lit, press the microphone mute key to unmute. Hardware mute at the keyboard level is independent of Windows software mute settings.

Can I use an external USB microphone with HP Envy x360 13 AMD?

Yes. USB microphones are plug-and-play on Windows 11 and do not require separate drivers. Connect the USB microphone and Windows 11 automatically detects it. Set it as the default recording device in Settings, System, Sound. USB microphones bypass the Realtek audio codec entirely, making them useful as a workaround when the internal microphone has driver issues. Most video call applications allow selecting the USB microphone as the input device independently.

Why is HP Envy x360 13 AMD microphone quality poor or very quiet?

Poor microphone quality on the Envy x360 13 AMD is typically caused by incorrect microphone boost settings in the Realtek Audio Console. Open Realtek Audio Console, go to Microphone settings, and increase the microphone gain or boost level. Also ensure Noise Suppression and Acoustic Echo Cancellation are enabled in the enhancement settings. These Realtek enhancements significantly improve microphone clarity for video calls. If Realtek Audio Console is not installed, the HP Audio Switch app from HP support provides similar controls.

Does HP Envy x360 13 AMD microphone work with Windows Hello voice recognition?

Yes. The dual-array microphone in the HP Envy x360 13 AMD is compatible with Windows Hello voice recognition if enabled. Set up Windows Hello in Settings, Accounts, Sign-in options. For Cortana and voice recognition to work well, ensure the internal microphone is set as the default recording device and microphone gain is set correctly in Realtek Audio Console. Poor gain settings are the most common reason voice recognition underperforms on Envy x360 13 AMD.

Conclusion

HP Envy x360 13 AMD microphone not detected on Windows 11 is caused by microphone access being blocked in Windows 11 Privacy settings, the HP Realtek audio driver being replaced by a generic driver that does not support the built-in microphone array, or the microphone being disabled in BIOS or muted at the hardware keyboard level. Enable microphone access in Privacy and Security settings as the first check since this is a software-level block that prevents all detection, reinstall the HP-validated Realtek audio driver from HP support to restore the correct codec initialization for the dual-array microphone, and verify the microphone mute key LED on the keyboard is not lit indicating hardware mute. Check the BIOS microphone setting if all software fixes do not restore detection.
