you execute  the block from gnuradio-companion I could not see a field for
that!!!!

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

Thanks,

the first HackRF that it finds.  To specify a particular HackRF, replace
the 0 with the serial number of the HackRF (found from hackrf_info).

Try reducing the sample rate to see if things improve.

with is kind of post, but when I got introduced to SDR I thought I will
spend exciting evening to explore this new interest. 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 ☹
