Hello,  
Sorry to trouble you again. I’m having enough doubt to use gnuradio for  
what I want. The following happens: I need to know which block gnuradio  
the  
“back” signal to audio. Can anyone help me?

Thanks and Regards,  
Rita Pessa

What do you mean “back”?  
Does the signal you have is demodulated?  
If yes, you can just connect your signal source to the block called  
“Audio  
Sink”.

Best,
