What interface is used to connect an S/PDIF sound card to the motherboard?

• A. HDMI
• B. Sony-Philips Digital Interface
• C. Universal Serial Bus
• D. Audio Jack

Answer: (B)

The correct answer is the Sony-Philips Digital Interface, commonly known as S/PDIF. This interface is specifically designed for transmitting digital audio signals between devices. When it comes to sound cards, S/PDIF allows for high-quality audio transfers without the interference that can occur with analog signals. By using S/PDIF, digital audio data is sent directly from the sound card to the audio receiver or other digital audio devices without the need for conversion to analog format. This minimizes signal degradation and maintains audio fidelity, making it the preferred connection for high-end audio applications. Other options mention different types of connections. HDMI, for instance, is primarily used for both digital audio and video and is not specific to audio alone. USB is a versatile connector but not typically associated with sound cards in the context of S/PDIF. Audio jacks usually refer to analog connections, which do not provide the digital transmission benefits of S/PDIF. Thus, the Sony-Philips Digital Interface is the appropriate connection for ensuring high-quality digital audio communication between the sound card and the motherboard or other devices.
