Rogue Amoeba Loopback not playing with Arena 7

[vj_anthos]

Hi,

Installed Loopback (latest version, but in Trial mode), runs great, audio playing. When I start Arena (7.0.5) with audio settings (see below) audio stops, although I can see the audio streaming through Loopback. When I change the External Audio FFT Input I get sound for a split second then nothing. Also if I create a new passthru source in Loopback, audio returns but it's not feeding into Resolume.

Anyone able to help out?

Found the 'issue', was missing monitors (speakers) in Loopback and presto..
