Hi all, I tried the experiment again today and I think I answered my question. I first ran the am_rcv.py example which pops a GUI, a very tiny one since the pre_demod, post_demod and post_filt blocks were commented. And this was hiding on the top left corner of my screen (I missed it). Assuming, there was no GUI for this code, I used Cntrl C to kill it. Although I wrongly assumed it was ended it actually was not destroyed and was running its internal processes, thereby heating the codecs.
I think the way the 'Destroy' destructor for the GUI's is written is applicable only if we gracefully exit the GUI (i.e. through File->exit on the GUI). It seems to me that Cntrl C does not totally kill the internal processes in the codecs and they continuosly receive the power. Lesson learnt : Avoid using Cntrl C to close your GUI's. I still am not sure of one thing though. When I run the example 'wfm_rcv_gui.py' with my basic d'board on the A side, the codec on the B side heats up. It seems like when I receive on A side the Codec on the other side has no job . If this is true, I think a better way to cut power to the unused codec would be to use the 'which_side' logic. Or this is probably what Eric was inkling at when he mentioned about ways to ameliorate the problem. Thanks for all your help.
