Hi Paul,

Would this work if you run these calls before the gr-uhd code in the 
flowgraph instances the device? This can be tested by inserting the code 
manually. It could be a solution, but I'm not even sure if you can 
insert a Python snippet in that location. However, if gr-uhd resets 
these settings when initializing the device, then this approach won't work.

Best,
Daniel.
