With this audio standard, the majority of the processing work is assigned to the main processor. It is responsible for synthesiser functions and mixes the digital data. The audio data is then converted and sent to a Codec. This then converts the data into audio signals.

In the recording direction, the Codec digitises the data and the processor is then responsible for converting the data into appropriate file formats and sampling rates. In the analog section, Codecs are also responsible for the mixing of other inputs and outputs such as those for the PC speakers, the microphone or the CD player.

•"Sound on Board" and SPDIF.

If sound is "on board", consult the motherboard description to find out whether a connection for SPDIF is available on the board. If you want to use this signal, you will need a speaker system with a decoder that can process digital signals. Make sure you follow the operating instructions for the decoder.

•Using the multi-channel audio function (optional)

If your motherboard is equipped with an appropriate Codec chip, you can use the multi-channel audio function. In general, the drivers for the Codec chip are linked to a program, which allows you to make the appropriate settings. If this function is available, you will find the corresponding manufacturer’s information in the motherboard documentation.
