Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 134, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
This policy determines whether the browser enables adaptive buffering for Web Audio. Adaptive buffering can reduce audio glitches but can increase latency to varying degrees. If this policy is enabled, the browser uses adaptive buffering. If this policy is disabled or not configured, the browser automatically decides during the feature launch process whether to use adaptive buffering.

Enabled: WebAudioOutputBufferingEnabled = 1
Disabled: WebAudioOutputBufferingEnabled = 0
Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
