High Definition Audio is the new audio implementation has been released
by Intel to replace the older AC97 standard.
The HD Audio specification is not backwards compatible with the AC97
standard.
The HD Audio standard defines one controller and a number of codecs with
5 signals running between them; BCLK, SYNC, SDO, SDI, RST. BCLK is a
24MHz clock signal. SYNC is a 48kHz frame sync. SDO and SDI are serial
output and input signals [referenced to the controller]. RST is a global
reset signal. The ICs use 3.3 volt signaling.
