Hello,

I have been trying to get the above mentioned working with the following
command but got the output shown:

dso@dso-LIFEBOOK-LH531:/usr/local/bin$ uhd_rx_nogui -f 92400000 -m FM -O
hw:0,0 -o 44100 --show-async-msg

line 345, in sink
    return _audio_swig.sink(*args, **kwargs)

How do I fix the bad argument?

Thanks,
Jeremy
