Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. The different signal assignments can cause trouble when AC’97 front-panel dongles are used with HDA motherboards and vice versa. If the headphones are not plugged in, the jack directs the audio to the return pins that are connected to the speakers.
