Thanks for the replies, guys.
Henry, I have drivers for the audio devices, yes. As I mentioned they work fine with other playback software, including the Tidal desktop app.
Eric, I don’t think it’s audio drop outs as I never get audio. It’s a Windows 10 machine with an i5 3550 (or 3350), 16gb of RAM, 120gb Samsung SSD. Music is stored on a second drive, which is a platter drive 500gb, I think. (it performs the same with “streaming” music from Tidal though so doubt local storage is an issue). Network topology is onboard ethernet from my mobo (Asus P8Z77) to Comcast’s Arris MTA. Don’t have the exact model # of the Arris, but I can get it for you when I get home from work tonight if needed.
