Intermittently an image, approximately 1.5"x1.5" appears in the center of the
desktop, covering whatever application is running. The image contains a
"sketch" of (presumably) a sound card and a label "Built In analog digital
stereo ( IEC958)". Sometimes the image stays on the screen for extended periods of
time, and sometimes it seems to appear and then disappear. (It of course stays there for
a long time when I am trying to see what is under it in the application.) This is a deal
breaker!
