Hi, I'm trying to pipe audio output on my raspberry pi3 to a snd-aloop device (hw:0,0,0). I have had no success so far and was hoping someone could point out how I could update the following command to send the output to my loop device? rtl_fm -f 132.076M -M usb -r 24k -l 0 -p 55 -E deemp -g 20 | play -r 24k -t raw -e s -b 16 -c 1 -V1 - I experimented with setting AUDIODEV=hw:0,0,0 but the command still seems to output to the pi's default audio device. My end goal is to receive the audio into my ham radio software, wsjt-x. There are graphical ways to achieve this, like using gqrx, but it kills the cpu on my pi. Many thanks, Chris
