Hy,
I just stumbled over the rtl-sdr without any prior knowledge about srd or the osmocom-project. I'm sorry if this hole project is just not for newbies but I wanted to at least ask for help. I planing to use the Noxon DVB USB Stick as an sdr to listen to our baby monitor and extend it's radius this way. My first step is to listen to a fm radio station by collecting some I/Q on the stations frequency. But neither the I/Q nor the cfile I created using the gnu-radio companion results in data I can listen to sending it to /dev/audio. I assume, I'm making some major mistakes so I want to ask for some hints or reading advice (some M to RTFM ;-)
Thank you, Hoffmann P

Note that rtl-sdr and osmocom-sdr are different pieces of hardware.
I'm not sure whether rtl-sdr is on topic on this mailing list. Let's see what others say.

A few points:
/dev/audio only accepts very special audio formats. Use a program to play audio files.
I/Q and cfile may need to be demodulated (gnuradio should do it) before you get audio information that you can play with the program for playing audio files.

All Right Peter, I think I found the right source, I just checked the mailinglist on which the GnuRadioCompangion-diagram was posted and "Tada"-the I found the(/one possible) demodulation.
Thanks for your advice, I'll stay tuned
