            Bug ID: 175760
           Summary: Audio track from getUserMedia has empty label
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Macintosh
                OS: macOS 10.12
            Status: NEW
          Severity: Normal
          Priority: P2

Audio tracks retrieved via getUserMedia have an empty label.

Run this:

  navigator.mediaDevices.getUserMedia({ audio: true, video: true })
    .then(stream => console.log(stream.getTracks().map(track => track.label)))

Expectation: ["Built-in Microphone", "FaceTime HD Camera"]
Actual result: ["", "FaceTime HD Camera"]

My devices all have labels.

When I run this:

    .then(devices => console.log(devices.map(device => device.label)));

I get: ["Built-in Microphone", "Built-in Output", "FaceTime HD Camera"]
