 Silicon Laboratories is the manufacturer of the radio ICs, that nowadays are the
 most often used radio receivers in cell phones. Usually they are connected with
 I2C. But SiLabs also provides a reference design, which integrates this IC,

 Audio Listing
-=============
+-------------

 USB Audio is provided by the ALSA snd_usb_audio module. It is recommended to
 also select SND_USB_AUDIO, as this is required to get sound from the radio. For
 listing you have to redirect the sound, for example using one of the following
 commands. Please adjust the audio devices to your needs (/dev/dsp* and hw:x,x).
 
 If you just want to test audio (very poor quality):
-cat /dev/dsp1 > /dev/dsp

-sox --endian little -c 2 -S -r 96000 -t alsa hw:1 -t alsa -r 96000 hw:0
