Hi,

I have one RTL-SDR and in my home computer it is working well. Now I am tryint to run in my office.
Here is Ubuntu 14.04 and GNU Radio 3.7.8... For a simple flowgraph just with RTL-SDR Source and a FFT Sink I can't vizualise nothing in FM (88 - 108 MHz). I have also here a USRP and a BlackRF and both oof then are working well. Is there something to solve this?

This is the output of Terminal to rtl_test -t

Found 1 device(s):

0: Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM

No E4000 tuner found, aborting.

And this is the output of GNU Radio.

Thanks so much,
