Thank You! II found the problem. All 3 of my computers have 4 USB plugs. I was using the far left one on each of them. on a whim, i decided to use the far right one and it worked. The sound was automatically better. I tried this on the other computers as well and it was the same result. I don’t know what is up with the far left USB slot, but it seems to be the problem. I wonder if this could be the problem for some of the others. I would never had thought so, but I knew at one point that it worked fine and then after thinking about it, I thought that maybe I had used the other slot before. I hope this helps others. Thank You!
