If you are trying to read the chip numbers it's obvious that some have been rubbed off

No mate, we don't rub off chip numbers here. Why the heck would we do that?
Cirrus and AKM use a white ink with a lot of contrast, other manufacturers use a darker ink. That's it all.

The DSP looks like it has been rubbed off and so does the chip to the left but obviously your camera can't pick up the faint ink used on these chips.

What's on the underside of the board ?

Could it be that a layer of lacquer applied after soldering, to prevent oxidization, makes the markings hard to read?

Gee I'll owe you a keyboard

The boards are with the manufacturer, I'm waiting for his news - that should be sometime soon.

In the meantime, I have 2 more pics.
