Hi,

i'm experiencing problems demodulating (NB)FM with rtl_fm, when
compiling directly on Raspberry Pi 2 with Raspbian: i just get noise!
WBFM does work. And i tested many things like calibration, frequency,
samplerate .. directly with a LPD (low power device).
rtl_tcp works nice with SDR# and i can verify the calibration with it.

In the end, i got paranoid and thought of compiler errors. So i tested
the same on a Raspberry Pi (1) B+ with same Raspbian image:
That works good. No problems!

Anyone else experiencing the same problem?
What is the solution?

kind regards,
Hayati
