Hello from Germany, I have used my configuration for a long time and everything went well. After upgrading to ROON 2.0 sometimes ! !! doesn´t find the BMC DAC connected wired using a high-end USB-Connection cable directly in my WIN11 Roon PC. All other music programs are working fine and use the DAC shown as a loudspeaker in WIN11 Audio Settings perfect. When it is working it sounds very good shown a the BMC ASIO Dac in the ROON audio configuration. Does anyone have a hint for me where to look? br Martin
