Trying to record analogue audio into DP11 via Focusrite Scarlett 6i6.
All 6i6 level meters bouncing nicely to show sound is getting into the 6i6, but when I set the input of a DP audio track to '6i6 USB 1&2', all I get is silence. DP will not receive the digital audio from the 6i6's USB out. Have also tried with 6i6 USB 3&4.
I've checked the Focusrite Control driver settings. They show the 6i6 accepting audio fine. Can anyone tell me how to latch DP's input to the 6i6's USB out?
It's probably something really simple that a seasoned user would know about.

Any advice gratefully welcomed.
