Pi B + Focusrite Scarlett 2i2 > No Sound

Hello,
I’m trying to run volumio on a Raspberry Pi B (1.0) with the usb DAC Focusrite Scarlett 2i2.
All I get is a constant intermitent sound (I’ve read this might be related to using the LAN port?).
The problem is I don’t get any kind of music reproduction at all, even though songs and radio seem to be playing.
Everything else seems to be working (web UI, spotify login).
I believe the the dac is not being loaded? This is the output of aplay -l:

root@volumio:/etc# aplay -l
