Alienware AW510H Microphone Does Not Pick Up Sound.

The boom mic may auto-mute when retracted. Extend it fully downward and retest.

Press the inline mute button on the cable to unmute. A click or LED indicates the current state.

Unplug and re-plug the headphone jack cable into a rear motherboard port. Avoid front-panel ports and unpowered hubs.

Right-click the speaker icon → Sound settings → More sound settings → Recording tab. Right-click the AW510H microphone and set it as both the Default Device and Default Communication Device.

Go to Settings → Privacy → Microphone and confirm microphone access is On for the system and for your apps.

In Sound settings → Recording tab, double-click the AW510H mic → Levels tab. Set volume to at least 80 and confirm it isn't muted.

In your app's audio settings (Discord, game, etc.), set the input device to the AW510H explicitly rather than Default.

Open Device Manager → Audio inputs and outputs. Right-click the AW510H mic and choose Update driver. If that fails, Uninstall device, then unplug and replug the headset to reinstall fresh.

In Sound settings → Recording → AW510H Properties → Levels, reduce Microphone Boost to 0 dB.

Move the headset to a direct motherboard USB port on the rear of the PC to avoid power noise from hubs or front-panel ports.

Install the latest Alienware Command Center (AWCC) from Dell's support site and apply any available headset firmware updates.

Flex the boom arm while speaking. If audio cuts out as you move it, the internal wire is broken and the headset needs repair or replacement.

Wiggle the cable at the USB plug while monitoring audio. If it cuts out, the connector is faulty. Replace the cable if detachable; otherwise replace the headset.

In Device Manager → Universal Serial Bus controllers, open each USB Root Hub's Properties → Power Management tab and uncheck Allow the computer to turn off this device to save power.

In Device Manager, uninstall the AW510H mic driver (check the box to delete driver software), then unplug and re-plug the headset to reinstall automatically.

Disable or uninstall third-party audio apps (equalizers, virtual cables, Dolby Atmos, etc.) one at a time and retest to find the conflict.

The microphone element in the boom has failed. The AW510H mic is not sold separately — contact Dell/Alienware support for a warranty replacement if eligible.

If none of the above work and the problem still persists, please check the Alienware AW510H guide HERE.
