+5. Sound features
+~~~~~~~~~~~~~~~~~
+Sound is supported by the ALSA driver: snd_usb_audio
+
+One 16-bit channel with sample and playback rates of 8000 Hz is the practical
+limit of the device.
+
+ Example - recording test:
+ arecord -v -d 10 -r 8000 -f S16_LE -t wav foobar.wav
+
+ Example - playback test:
+ aplay foobar.wav
