Not all sampling rates will be supported by your hardware.
Leave the device name blank to choose deafult audio device. 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.
