Hi guys!

Using Alesis Multimix 4 USB fx audio interface. Connected to Mac (Sierra 10.12.6) with usb, trying to use it on Guitar Rig 5. Guitar Rig seems to find Alesis as input sound can be seen, although no output. "Audio and midi settings" in "Routing" shows gives no options for Output connection.
Below are screenshots with the settings I have.
Would appreciate any help! Thanks!
