Fix my Bioshock 1 problem

When I started Bioshock 1 on my Dell XPS Machine, I realized that audio wasn't working.  Not matter what I do, the audio just didn't come back.  After reading this page, I tried the following, and surprisingly, it worked:

• Right click on Sound icon on system tray, and select "Recording Devices".  On Stereo Mix, select "Enable". 

And that's it.
