How do I allow Chrome to use my microphone programmatically?

Question

I am currently trying to run some tests made with webdriverjs and chromedriver but they need microphone permissions.

This is the popup that shows up:

Answer 1

Similarly, for use in Splinter

    from splinter import Browser
    from selenium.webdriver.chrome.options import Options 
    chrome_options = Options() 
    chrome_options.add_argument("--use-fake-ui-for-media-stream") 
    Browser('chrome', ** {'executable_path':'chromedriver'},options=chrome_options)

Answer 2

For those using Python, this worked for me:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument("--use-fake-ui-for-media-stream")
driver = webdriver.Chrome(chrome_options=chrome_options)

Answer 3

You can whitelist a url for audio-capture by providing chromedriver with the hardware.audio_capture_allowed_urls preference.

...
chrome_options = Options()
prefs = {"hardware.audio_capture_allowed_urls" : ["example.org"]}
chrome_options.add_experimental_option("prefs",prefs)
driver = webdriver.Chrome(chrome_options=chrome_options)

Answer 4

A little late but pasting how to do this here for others looking for the same.

const webdriver = require('selenium-webdriver'), By = webdriver.By, until = webdriver.until,Builder= webdriver.Builder;

var chrome = require('selenium-webdriver/chrome');

var chromeOptions = new chrome.Options()
.addArguments('allow-file-access-from-files')
.addArguments('use-fake-device-for-media-stream')
.addArguments('use-fake-ui-for-media-stream');

var driver = new webdriver.Builder()
.forBrowser('chrome')
.setChromeOptions(chromeOptions);

driver = driver.build();

A fresh profile is loaded each time you run selenium, hence changes you make to the preferences and website permissions are not preserved between sessions. To amend this we need to tell selenium which profile to load.

Step 1. Find your Chrome preferences file: www.forensicswiki.org/wiki/Google_Chrome#Configuration

Step 2. Copy the folder Default somewhere. I will assume it is copied to /some/path/allow-mic/Default.

Alternative Step 3 (this is easier): Before copying Default visit localhost:1337 with Chrome and set mic to always allow.

Step 3. Edit allow-mic/Default/Preferences, find the tags "profile", "content_settings" and "exceptions" within each other and add

"media_stream_mic":{"http://localhost:1337,*":
                                          {"last_used":1470931206,
                                           "setting":1} },

to "exceptions". You should end up with something like:

...
"profile":{
     ...
     "content_settings": {
         ...
         "exceptions": {
             ...
             "media_stream_mic":{"http://localhost:1337,*":
                                      {"last_used":1470931206,
                                       "setting":1} },
             ...
         },
    },
},
...

Step 4: Configure selenium to use the edited preferences:

var chromedriver = require('chromedriver');
var Webdriver = require('selenium-webdriver');
var chrome = require('selenium-webdriver/chrome');

var opts = new chrome.Options();                   
opts.addArguments("user-data-dir=/some/path/allow-camera");

var driver = new chrome.Driver(opts);

You can check that the correct set of preferences (Profile path) are in use by opening chrome://version/.
