Make sure your microphone contains any special character. There is suggested name of microphone "Batería de micrófonos internos".

    I download the 2017.3 beta, the string is not empty now.
    But it still has a bug, Microphone.Start(devicename) always start the default microphone.

    I have the same problem: two devices with empty names. So I only can use Microphone.Start(null ... ) and work with the default microphone, but I can't use the other device because Microphone.Start only works with string. Maybe Microphone.Start can use the index value in addition to the string value.

    I have the same problem. I am working with webcams and microsoft got the registered trademark symbol behind the name which cause problems as well.
