DAC not detected?

Hi, I’m running version1.3Beta on a BBB. I have two DAC’s both should be supported in Linux, however they not appearing in the MPD list

root@volumio:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Black [TI BeagleBone Black], device 0: HDMI nxp-hdmi-hifi-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0

Both DAC however indicate Lock + USB (LEDS) are on…

Volumio seems to play tracks fine, no problem there.
