Port speed Music and Sound FX Audio Started by Calin May 11, 2025 03:52 PM 0 comments, last by Calin 1 hour, 41 minutes ago Author Could someone please explain in lame language the following thing: If I have a sound board attached to a motherboard slot the clock sped of the sound board will be the same to the clock sped of the motherboard. However the digital signal on the sound board is transformed into analog signal and the output signal at the female plug will be analog. But how about other type of ports? If we take the HDMI port for example? What is the data exchange rate?
