ProtoDAC TDA1387 X8 project

Found the test file. Sorry for the dumb question, I hear him saying "My voice is out phase" what shall I hear, I hear some strangness but not sure what I should be hearing

The male voice on the test file says:

This is my voice on the left
This is my voice on the left hand side
This is my voice on the left

This is my voice on the right
This is my voice on the right hand side
This is my voice on the right

This is my voice in the center
This is my voice coming from both left and right
This is my voice in the center

My voice will be out of phase on three
One, two,  three, four, five, six, seven, eight, nine, ten
-in phase-  ----------------- out of phase ------------------ (it will sound thin and hollow)
My voice is out of phase

The track is a 16-bit 48 kHz FLAC file and so very high quality. There should be no distortion or any other audio artifacts whatsoever.

I would also follow @hifinet advice and reexamine the solder joints.
