It can happen that you do everything right in Windows and still not hear. Driver and other app conflicts are the usual suspects. Also remember that NotePad is a 32 bit application. If Win 10 is set up for 64 bit only, that can also get in the way. Let’s hope that the Tutorial helps you.
Most programs made for the 32-bit version of Windows will run on the 64-bit version of Windows. The fact it is 32-bit is mostly irrelevant. First did it ever work? Second try Note Pad by itself no others apps running if it works then there is a conflict. For instance don't have You Tube running even in the background.
