Just a quick follow-up on this, the OP did perform the test of the On-board audio as output device and it worked fine, both with radio stations and with his own thumb drive based scanned in tracks as MPD library.
He also then bought another mSD card and flashed a fresh 4.4 image onto it, and after configuration the same exact problems occurred with using the I²S output, at which point it seems safe to point the finger at a defective Allo DigiOne Signature HAT.
The OP has promised to follow-up once he receives a replacement, in the meantime thanks again for the troubleshooting suggestions.
