Please be aware that some of us had issues with 4.38 and Windows 10 (1803) where the device disappears completely. I had to downgrade to 3.29 I don't know if there will be a fix.

No need for Dante Via or anything else. You can grab the driver here: https://www.musictri.be/Categories/Behringer/Computer-Audio/Interfaces/UMC1820/p/P0B2J/downloads NOTE: This is running Windows 10 v1709 - I've not yet upgraded to 1803 and I know there are some sound routing changes in that version of the OS, so this may not work in 1803 (will update you when I install 1803). Before installing, I could only see the "Main Out (Line 1/2)" and main input devices from within Windows 10's sound control panel, apps like RadioDJ, VLC etc. After installing the driver, I can see "Main Out (Line 1/2)" then also "Line Out" devices for outputs 3/4, 5/6, 7/8 and 9/10 - same with the inputs! Tested all outputs successfully, and I can only imagine the line in devices also work. One thing to note is the volume's pretty loud on the line out devices (at least for my Zenyx 2442) so I had to reduce each output's volume down to 31/100 in Windows 10's Sound control panel. The other thing to note is that if you disconnect the interface and reconnect it, Windows 10 has a habit of re-indexing the outputs so that if, say, you had VLC set to use Line 5/6 it will likely default back to Main Out 1/2... and I also found the volumes resetting. Still, not too long to reapply the volume / output selection as needed. Anyway, thank you Behringer!
