 Not all sampling rates will be supported by your hardware.
 
 Leave the device name blank to choose deafult audio device. \
-Audio device names may look like hw:0,0
+ALSA users with audio trouble may try setting the device name to plughw:0,0
 
 The audio sink can have multiple inputs depending upon your hardware. \
 For example, set the inputs to 2 for stereo audio.
