They are (ver) different. They just use the same connector and cable but
any similarity ends here.

HDMI sends video data, R, G, B over three pairs of wires (differential)
and sends it as serial data. Sound data is multiplexed with the video
data and that sound data is just another bitstream and can be anything
from plain PCM to one of the multichannel formats.  

I2S, via HDMI, uses the three R, G, B line pairs to transport the 3 I2S
signals: autodata, the bit clock and the word clock. There is not
official standard which signal is on which line/pin and what the signal
levels are.



does the all-black SB sound better than the white SB?
