I was getting CRC errors (on the link from the Mytek back to the computer). These depended on the buffer sizing and other activity going on in the computer. The problems went away when the buffers were made somewhat larger. They also went away, if I removed the CPU load that I was generating for experimental purposes.
This is not solid proof of software causation and it doesn't identify which software might be defective (OS, driver, DAC USB firmware), but it seems a plausible deduction. Other hints include watching the error counters increment while doing specific things, e.g. running Firefox with a complex web page and using the mouse to scroll the window. The idea was to create various quasi-random stress on the system and see what happens, with the goal to discover the system limits by "breaking". [Something OK with a computer system, not advisable when operating a vehicle or aircraft. :) ]
