Nope, UMC22 should be using a BB PCM2902 or a clone thereof (like the UCA202). Should be perfectly serviceable in practice but firmly on the 16-bit side of things (about 93 dB(A) output and 87.5 dB(A) input dynamic range according to Julian Krause, DAC THD+N of about -86 dB, and the DAC should be a multibit affair so expect some low-level nonlinearity - see NwAvGuy UCA202 review).
Honestly, if you have some decently-implemented onboard audio available I'd be strongly looking at that instead, even an ALC887 should have it beat by several dB. It's about on ALC883 level or so...
This is not a knock on the UMC22, which is a super cheap interface that still is full-featured and quite solidly built, and by all accounts works decently (even the microphone preamp has nice and low EIN). One would just wish they'd at least look at the kind of Realtek chips shipping in 192 kHz / 24-bit capable USB microphones these days for a potential redesign (even if I've had one of these and found an input dynamic range of about 90 dB, so 24 bit is a bit of a joke). It seems the demand for high-performance single-chip USB audio codecs just isn't all that great for some reason.
BTW, if anyone with moderating powers is reading this, I'd think this thread could finally be moved to the audio interface department...
