On the first page I read EIAJ. This is a different standard than I2S and I'm pretty sure that ES9018 will not take it.
I used play with a NOS DAC (TDA1545A) that takes it, but I believe it is a dying standard.
I may of course have missed something.......

You may be able to find the pins supplying what you need, but it will take a scope to verify, and a lot of time/luck. (Or someone who has done it before).

Is that picture of the data line with no music playing, or just a snapshot? Typically a scope will have a very hard time locking onto the Data waveform, as it the period of the square wave will constantly be changing.

Are you certain it is actually I2S and not some other format?

My best guess is that it is not 64fs I2S.

The current the teleporter draws will vary depending on the circumstances of its use.
