The sourceId does indeed remain the same after a page reload.

>From the spec:
"sourceId of type DOMString
    The application-unique identifier for this source. The same identifier must
be valid between sessions of this application, but must also be different for
other applications. Some sort of GUID is recommended for the identifier.
Returned for all types of sources (video, audio, etc.). "
