Yes, actually in foreground. It's always running, shown in task bar.
It's as if the WDM is not "connected" to my DAC, even though MC27 is running and output device is designated as the DAC.
I should also mention that when I start playing a track in Amazon, I do see the volume level active in win sound panel, AND I see IPC active in MC27 playing now. It's just that the audio is not output to the MC27-specified output device (DAC).
