Salute, IceHeart357!
You've encountered the infamous WinXP sound bug, I'm afraid.
That's the bad news...
The good news is there is a fix!
Go to the
Wings of Valor website. That's a favorite "watering hole" of a lot of RB3D pilots, particularly those of us who like to fly on-line. But I digress...
On the left-hand side of the home page, you'll see a section called
Resources. Under
Resources, you'll see an "XP Related" hyperlink. Click on it.
You don't want Pepe LePeu's "XP Sound Workaround"...you want to download the "XP Utility." Download it and follow the instructions in the "Read Me" file to install it and use it. Although it adds one extra step to launching the game, it fixes the problem and is really very, very simple to use.
Good luck, and good hunting!
