Hi Ray, 

The feature request is an interesting point and it has come up before on the list:

This has gotten really expressive particularly after connect() began supporting AudioParams as targets. Do you have a use case in mind that cannot be covered by such a gain node that would be covered by an envelope node?

The suggested approach in that discussion was to do exactly what you have done: create a looped BufferSourceNode with a unity signal.  It only really needs a single sample, not 1024.

Offhand I don't know why this should not work on Chrome 22 and I don't know if there is a bug or not. Perhaps one of the Google folks will chime in.
