Summary
-------

During the wait apps, Wait() WaitUntil() WaitForRing() WaitForSilence(), no audio is generated.  Since no audio is generated audiohooks arn't mixed with anything causing apps like ChanSpy to not work.  This patch adds silence generation to wait apps to create audio.


This addresses bug 16524.
