gr-osmosdr v0.1.x-xxx-xunknown (0.1.5git) gnuradio 3.7.8
built-in source types: file fcd rtl rtl_tcp

FATAL: No supported devices found to pick from.

Trying to fill up 1 missing channel(s) with null source(s).
This is being done to prevent the application from crashing
due to gnuradio bug #528.

Source has no sample rates (wrong device arguments?).
