Hi, This is my first attempt at gnuradio flows. I'm trying to run some of the tutorials i have found around. I use Ubuntu 14.04 x64, gnuradio 3.7.1, usrp x300 with latest uhd. I have a very simple flow with an Osmosdr Source connected to a Baudline Sink. I get the following error on execurion:
UHD Warning:
The hardware does not support the requested RX sample rate:
Target sample rate: 0.032000 MSps
Actual sample rate: 0.195312 MSps
['baudline', '-stdin', '-record', '-spacebar', 'recordpause',
'-samplerate', '32000', '-channels', '2', '-format', 'le32f', '-quadrature']

Attaching top_block.py and Tutorial.grc. Searching mail archives and the
web didn't help. Maybe I don't know yet how to ask it correctly:(
Appreciate any suggestions.
TIA
