still no audio is captured, apparently...
this card has 16 inputs, maybe I should specify somehow which one
should be used?
The aplay/arecord has 'D' option. This option is used to indicate PCM
device.
When you omit this option, 'default' PCM device is used.
In system with PulseAudio, 'default' PCM device is set as input/output
from/to PulseAudio.
I guess you record from PulseAudio, not directly from your device.
Would you test with 'D' option? Like:
$ arecord -D hw:UFX1604 -c 16 -f S32_LE -r 44100 /tmp/test.wav
