Coming back to this late, sorry. Just want to note that scook's instructions did not work for me. The mixer keeps disconnecting, and the sound coming in when I can get it to work is terrible. This is happening on both Windows 10 computers (including the one that I had thought it was working with).
Also, when I change the driver mode to ASIO, I can't even see most of the mixer's inputs in Cakewalk, despite Windows recognizing them.
Screenshots attached. I'm giving up. Really bummed that I wasted money on this mixer.
