Official documentation guide
How do I allow a Chrome site that was previously blocked from using the microphone?
Short answer
Open the site, select its site controls, change Microphone to Allow, and reload if Chrome requests it. The operating system must also allow Chrome to use the microphone.
What the documentation establishes
- A blocked site's microphone setting can be changed in Chrome site controls.
- Operating-system microphone access can still prevent recording.
Scope and limits
Documentation synthesis; no hands-on testing was performed. Behavior can change with software version, language, permissions, focus, device, and application configuration.
