Default Recording sound with external sound card

Hi folks,

I have here a Creative Labs SB0270 Soundblaster:
Code:
uaudio0 at uhub1 port 1 configuration 1 interface 0 "Creative Labs USB Audio" rev 1.10/1.00 addr 2
uaudio0: audio rev 1.00, 13 mixer controls
audio1 at uaudio0
It connects to the computer via USB, and has red/white phono Line In connection. I have been using it to record audio on a Windows laptop with Audacity, but would like to move to OpenBSD. Unfortunately, aucat -f /dev/audio1 -o test.raw seems to produce a silent file no matter what I do.

Any tips?

mixerctl -va:
