Still no success:

# sysctl hw.usb.uaudio.default_rate=16000
hw.usb.uaudio.default_rate: 0 -> 16000
# dd if=/dev/dsp1.0 of=/dev/dsp0.0 bs=64
dd: /dev/dsp1.0: Invalid argument
0+0 records in
0+0 records out
0 bytes transferred in 5.000237 secs (0 bytes/sec)
# sysctl hw.usb.uaudio.default_rate=32000
hw.usb.uaudio.default_rate: 16000 -> 32000
# dd if=/dev/dsp1.0 of=/dev/dsp0.0 bs=64
dd: /dev/dsp1.0: Invalid argument
0+0 records in
0+0 records out
0 bytes transferred in 5.002866 secs (0 bytes/sec)

In the meantime, the log shows:
