In order to play sound, your application must include the following components:
• Hardware, which can be a sound card or a sound chip
• A device driver for the hardware
• Application programming interface (API), used by the application/programmer to talk to the device driver (sound card or a sound chip)
The EUROS Audio System allows playback and capture of audio data from audio devices such as external sound cards/chips, codecs.
The basic hardware element needed to produce a sound is an audio chip or card. The EUROS Audio System allows attaching a number of audio chips (or cards) at the same time. The user can create and delete an audio device driver at any time during application execution. The EUROS Audio System uses the EUROS I/O system for transferring data and controlling the device driver.
