@ Bass Guitar, I understand your suggestion is that I purchase a computer dedicated solely to use as a DAW. I would, for sure, be happy to do that if I were a serious sound engineer. However, although you are no doubt more experienced than I in setting up DAWs, you don't know what, precisely, causes Cakewalk to spin up this error message about an Intel audio device which has no connection to Cakewalk as evidenced by the audio preferences pictured in my earlier post. Perhaps I can't call it a bug because I do not have a dedicated system, but I will need to move on to a different DAW if this is not something that can be fixed on my system. I've disabled the Realtek ASIO driver, but as you note, that's not my issue. In Device Manger, disabling the Intel Display Audio in "Audio inputs and outputs" does not eliminate the problem although disabling Intel Display Audio in "Sound, video and game controllers" does, but that makes the display audio inaccessible. I've updated the driver and the firmware for the Dell monitor.
Of course, it may be a bug in the Intel software that only Cakewalk is detecting. I tried a different HDMI cable just to eliminate that suspect. I haven't quite given up yet and I appreciate your comments as well as the comments of all who have responded. This seems to be a good community and I'm hoping to remain with y'all if I can get past this ... anomaly.
I will try reaching out to Cakewalk support and will post here if I ever solve the problem.
