Help with a PlayBuf Player In which chase a simple Saw.ar() will run

Dear Community,
I need help with a complex Script.
This Script are to long to be published here.
I have coded a Script which is similar to a Vocoder.
The Problem is, that I need a Sound Source in the first Place of the Synth.
And when this Source is a Saw.ar() than all is working.
Too is all working when the Sound File is bypassed through the remanding of the Synth.
But when the Vocoder is applied to the PlayBuf.ar then I hear nothing else then a crackling.
So the Problem is that I have no Idea which is the Way to become my Synth Working.

In hope of every constructive Idea

Sorry I have had no Idea where may Failure was.
And by a little Playing the Failure was resolved.
The Problem is that I have now no Idea what I have changed.
But the Synth now run Correctly.
