Trouble using file source

Hello everyone,
I am using GRC to receive digital signals. I am getting perfect audio
and perfect scopes. I hooked up a file sink directly to the receiving
device (RTL2832). On replaying the capture, the gui greys-out. The gui
never greys-out when receiving live. I have the throttle after the file
source as was shown in tutorials.
Is it possible that the capture is being done incorrectly? Or is the
problem with the replay? What am I doing wrong?
Thanks,
Matt

What’s the sample rate of the throttle block? Are you setting it to
replay the file when it finishes and how many samples are in the file?
