yes, you're right, it is for I2S, board has SPDIF but no extra power input. Thanks for your efforts!

Okay, most of the part values are marked on the board. There are some caps that don't have values shown.

Please inventory the parts you have and separate them into two groups. One group should be parts that are marked on the board. Those are not a problem since you know where their locations are, right?

The other group should be parts that are not clearly marked on the board. We need a list and pictures for the components in the second group. For example, looks like maybe there are some film caps and some electrolytics. What are the values you have and what quantity of each value, etc.?

Nope. Only what's in the data sheet. But, if you sketch one up please post it so future builders can find it.

What I can say that a lot of caps are redundant, just connected in parallel, appears like this design was meant to look "cool", by having more parts than really needed.
