Help! Is there standardization in i2s?

Really, No standard, What year are we in??? I2s has been around quite awhile. Someone better get working on that 😤 

It brings back memories of an old B&O receiver… I always wondered why?

Not yet, but i agree it should be and will be standardize.

Nostradamus and CAlifornia Psychics would agree that the 6moons article is informative…I 
looks like I might have to make my own cable.
Alvin - Thanks for the info!

I2S is an electrical specification, not a mechanical/physical one. Vendors using it outside their box normally turn it (I2S is single-ended) into an LVDS set of differential signals. The allocation of those signals to physical pins in the HDMI connector is different between vendors.
