Are any of you using the Realtek ASIO driver?  This driver has known issues (it doesn't even pass the basic ASIO SDK tests). I had exactly the same symptoms described above on my laptop ( with a pretty new i9 6 core/12 thread processor) using the Realtek ASIO driver. The fix is to switch to WASAPI mode in Preferences->Audio->Playback and Recording.
