# Microphone Volume is Automatically Adjusted

**ISSUE:**

When using Zip Captions in Chrome on Windows, the volume of the microphone is adjusted, and in a recording the user cannot be heard.

**CAUSE:**

Chrome has the ability to manage the volume of the microphone. This setting is called “WebRTC adjust the input volume”.

**SOLUTION:**

1. Disable the feature by turning off the following Chrome Flag: 'WebRTC to adjust the input volume'. In order to do this, navigate to `chrome://flags` in your Chrome address bar and search for the 'WebRTC to adjust the input volume' flag. Turn it off by changing the dropdown to 'Disabled'.
2. Installing the ‘Disabled Automatic Gain Control’ Google Chrome Extension from the Chrome Web Store will also disable this feature. You can find it at <https://chromewebstore.google.com/detail/disable-automatic-gain-co/clpapnmmlmecieknddelobgikompchkk?pli=1>.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.zipcaptions.app/known-issues/microphone-volume-is-automatically-adjusted.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
