Simple Ham Radio FM receiver with rtl-sdr
johntimber
Hi,

I tried to use my current DVB-T dongle and the raspi, as a first project.After a succesful compilation of rtl_fm (I can elaborate, if needed), I'm currently facing various issues for a "complete" FM receiver.1/ As "play" (from the sox package) can't find any default device (how to set that ?), I used aplay instead from the ALSA package. After much testing it appears the current sound driver (and/or aplay) only accept raw files sampled at 44100 and 48000 Hz. When using other sampling rates files, aplay doesn't complain, no sound is output, the raspi just hangs, and a reboot is required. I guess it is a sound driver bug (or a limitation ?).

Please help.

I didn't find the right solution from the Internet.
