I know this is an old thread but being an old guy I felt I needed to reply anyway. If any of you ever used a 8086 286, 386 or 486 computer running windows 95/98 there was a "driver" you could get called speak.exe that would allow you to play windows sounds through the built in computer speaker. The speaker was internal and made beep sounds to alert you to boot alerts, errors while booting, etc. I'm not sure that today's computers come with a "speaker" like the computers of yesteryear did but if they do I would think a quick Google search would yield the driver. If I remember right cnet and maybe driverguide have the file. It may not work on newer computers as it was built for Windows 98 but can't hurt to give it a try.
