Do you have any ouput from it?  Any error messages?  Could we also have the output from hackrf_info?

Thanks,

  Dominic

It's a setting on the osmocom source block.  See the attached image.

Thanks,

But my experience is just ending with allot of OOOOOOOOOOOO or aUaUaUaU !!!! I read allot about what could be the reasons that is either the double clock or my sound card is not able to handle the sampling rates , etc…..but so far not able to solve the challenge. I just got my new MacBook Pro with good configurations and the sound card is configured to handle 44.1Khz. I did upgrade the Hackrf firmware to 2017-02-1 package. I am using gnuradio and my macport should take care of the updating to the latest ver. But again I do not seem to be able to hear even a simple FM station just noisy rains ☹
