I am trying to build *a USB sound card and trying to finalize the

I safely take that PCM2706 USB-I2S conversion will not alter the
following parameters before passing the digital audio to the DAC.
(assuming no jitter)

The "assuming no jitter" could turn out to be the place where your
design fails.
You need to make that "making sure to keep the jitter within the
specs"
The jitter of the timing is the one place where noise etc can sneak
into your
design. The digital signals cn be considered perfect except for this
issue.

The noise floor can be lost if you let the digital bits leak into the
audio
part of the design.
