My BCD325P2 is producing a constant high pitched "squealing" sound through my PC when connected via audio cable. I noticed that the sound stops if I disconnect the USB cable and returns when I reconnect it. I also have a BCD396XT that does not have the same issue.

You need a ground loop isolator between the scanner and computer. Not having one in place can damage the scanner.

And maybe even an attenuator also. Too much input into the computer overload, also can cause that.
