If you are using sio for sound capture and playback, only the sio package is needed. For device scanning and APIs, the host package provides the necessary support.

For porting, see the porting guide and contributing.

Below is the status of sio ports. Items marked with an "X" in plain text (checked off in html rendered markdown) are incorporated into sio, potentially with alpha status. Items marked with a "?" indicates we do not yet have sufficient knowledge to judge whether or not the item is a TODO. Related discussion on the issue tracker is welcome. Items marked with "-" are those for which we think the functionality is not relevant or not sufficiently supported by the external software interface to add to sio.

In the event there are opinions about the content of the list itself, such as whether to support JACK, whether to interface with Android HAL, the issue tracker is our best means of coordinating the discussion.
