Audio

In order your application to play sound the system must include the following components:

- Hardware - sound card or sound chip

- A device driver for the hardware

- Application programming interface(API) used from the application/programmer to talk to the device driver

In EUROS this whole system is named EUROS Audio System. The EUROS Audio System allows playback and capture of audio data from audio devices (external sound cards/chips, codecs).

The basic piece of hardware needed to produce a sound is audio chip or card. The Audio system of EUROS allows attaching number of audio chips at a time.
