Dear Lars,
I have just did the experiment according to your reply.
The attatched png file reflects the FM demodulated audio signals could monitored via HDMI output or Zedboard Phone Jack depending on which audio playback equipment you choose in the Sound control of Ubuntu System X-Windows interface.
Nevertheless, ' the following command `iio_fm_radio $1 | aplay -D default:CARD=ADAU1761 -r 48000 -f S16`.' caused error.
Besides, during the tuning to an FM station I compared the AGC modes, I think the hybrid or manual mode would be better than fast_lock for your reference.
