- " DESCRIPTION: \n"
- " When invoked without any arguments, it displays information about all \n"
- " sound devices in the system. \n"
- " \n"
- " When invoked with arguments, the program tests if device can be opened \n"
- " with the specified arguments. All these arguments must be specified: \n"
- " - id The device ID (-1 for the first capable device) \n"
- " - rec/play/both Specify which streams to open. \n"
- " - clockrate Specify clock rate (e.g. 8000, 11025, etc.) \n"
- " - nchan Number of channels (1=mono, 2=stereo). \n"
- " - bits Number of bits per sample (normally 16). \n";
