`--use-file-for-fake-audio-capture` doesn't work on Chrome

See original GitHub issue

Current behavior:

I use --use-file-for-fake-audio-capture for testing getUserMedia behaviour on Chrome. https://github.com/cypress-io/cypress/issues/4160

But cypress v3.5.0 and v3.6.0, --use-file-for-fake-audio-capture doesn’t work it.

Desired behavior:

--use-file-for-fake-audio-capture works on Chrome.

Steps to reproduce: (app code and test code)

// plugins/index.js
module.exports = (on, config) => {
    on('before:browser:launch', (browser = {}, args) => {
        if (browser.name === 'chrome') {
            args.push('--use-fake-device-for-media-stream')
            args.push('--use-fake-ui-for-media-stream')
            args.push('--use-file-for-fake-audio-capture=cypress/fixtures/sample.wav')
        }
        return args
    })
}

and args output

I tried to absolute wav file path, but it doesn’t work too.

according to https://bugs.chromium.org/p/chromium/issues/detail?id=1032604#c37 plugin/index.js add chrome args “–no-sandbox” demo code:

on('before:browser:launch', (browser = {}, launchOptions = { args: [] }) => {
    if (browser.name === 'chrome') {
      // https://bugs.chromium.org/p/chromium/issues/detail?id=1032604#c37
      launchOptions.args.push('--no-sandbox')
      launchOptions.args.push('--allow-file-access-from-files')
      launchOptions.args.push('--use-fake-ui-for-media-stream')
      launchOptions.args.push('--use-fake-device-for-media-stream')
      // mp3 not work
      launchOptions.args.push('--use-file-for-fake-audio-capture=tests/fixtures/hello.wav')
    }
    return launchOptions
  })

I’m facing the same issue with MAC Chrome. Did you find a solution?
