Help: Yamaha USB and Alesis monitors

I just got my UR22mkII today, and updated the Yamaha USB driver. I now have to run my Alesis M1Active 320 monitors (USB connection only) through the Yamaha USB (“USB Audio Codec” has now disappeared). Problem is that now only hi-mids are outputting through the speakers as if I have a non-existent sub somewhere. Any guidance?

Update: Might be Aria Player; EW Play works fine.

Update 2: Definitely a conflict with Aria (latest driver and engine installed). Any chance this is on Steinberg’s end?
