[bug] noise cancellation not activated on external headset

[holzgeist]

Describe the bug

When using an external headset, noise cancellation is deactivated.

I did some digging. Is it possible that a8ba441 can be reverted now that flutter-webrtc/dart-webrtc@dc362d5 has landed in dart-webrtc?

To Reproduce

Connect an external headset, get its deviceId, add it to AudioCaptureOptions, start a call

Expected behavior

Noise cancellation works
