aqualung [--output (jack|pulse|alsa|oss|sndio|win32)] [options] [file1 [file2 ...]]

Normally you should be able to start Aqualung without any options. This case the output device will be selected by probing for a usable driver (in order of JACK, PulseAudio, ALSA, OSS) with default parameters.

If no driver could be started with default parameters, or you want to explicitly choose a suitable output configuration, you have to tell the program which output device to use. This is possible with the -o (--output) option. There are specific optional parameters for all five output drivers. You can also specify which sample rate converter you want to use, or request a list of available converters. You may also control another instance of the program remotely, or add files to the Playlist.
