Yes (i use a delta 66 for jack):

loading driver ..
apparent rate = 48000
creating alsa driver ... hw:1|hw:1|1024|2|48000|0|0|nomon|swmeter|-|32bit
control device hw:1
configuring for 48000Hz, period = 1024 frames, buffer = 2 periods
ALSA: final selected sample format for capture: 32bit little-endian
ALSA: use 2 periods for capture
ALSA: final selected sample format for playback: 32bit little-endian
ALSA: use 2 periods for playback

It also tells you when it fails selecting a bit depth. I don't use 96khz yet 
[too demanding disc space requirements]..
