its my understanding that when you have the dac behind the i2s 'curtain', you don't get to see thru to it. or, your computer doesn't.
your computer sees a devices that does not report vol control ability (its job is to send usb data over i2s and so vol control is not really relevant).
if your dac was the 'end point' and not the usb/i2s converter, THEN windows would probably 'see' a vol control *control*.
at least that's how I understand the driver and topology flow.
this is a good thing, though, as you can't accidentally attenuate at digital level. you don't want to.

As for your question, the reason why the volume control doesn't work over USB, but works over S/PDIF is most likely because the latter is not a "generic" interface. There is a "sound card" behind the S/PDIF port whose driver isn't running via ASIO or WASAPI.
