Hi Jay - then show us a simplified GRC file which demonstrates the problem as you outlined using the green and red boxes.
There are pluto sources or sinks in the GRC file you sent.

Hi all,
I had a non-GRC application (zmqPUSH.py) sending messages to GNURadio for Transmission. I had successfully got that msg inside gnuradio using ZMQ PUll message source and I debug that with message debug print and it printed perfectly ok. I am testing a loopback where that message is transmitted using an audio sink and received and decoded using an audio source. I can see in QT time & Frequency sink that it is receiving the messages.
But for some reason it is not properly decode the message using message debug. It looks like my Audio source is playing aUaUaUaU (I know this may be related issue to my my audio sink/source configuration), I googled and tried bunch of things suggested here : https://github.com/rxseger/linuxproblems/issues/4 but that didn't work either. Normally I test my audio source and sink with a simple sin source and that works fine without anything in the "device name".
Is there anything I am missing here ? Do I have to configure something specifically ? My end goal is replacing the audio sink and source with PlutoSDR for real time transmitting.
I know I should update my gnuradio version to a newer version but unfortunately, I don't have those leverages as I have other co-systems such as ROS Kinetic and external simulator which only runs properly with 16.04.
I had attached my files for your reference. Any help would be greatly appreciated.
With Regards,Jay Patel
