I recently started having problems when streaming music using my Antipodes S30/S40 combination with a Chord Dave DAC. I control everything with an iPad. Usually within a minute or two of playing music I receive an error stating, "Roon has lost control of the audio device". I restart the song, but I continue to receive error messages to the point where I can't listen anymore. I use a Spectrum modem and router. Is the problem with Roon, my WiFi, or my S40? Any assistance is greatly appreciated.
