A screen shot indicating the AP192 sound card noise level with nothing
connected to the inputs is attached.
Reference level is full scale (4Vrms).
Aside from the few discrete spurs which differ between both channels the
region from 1 - 10kHz is fairly quiet.
Technical Notes:

FFT bin equivalent noise bandwidth ~ 3Hz.
96 KSPS.
