There is a problem with the sound driver in XP but someone in another forum advise how to fix it
<<<<<<<<<<<<<<extract as follows>>>>>>>>>>>>>>>>>>>>
Now, what is causing the problem is a compatibility issue with winmm.dll, a Windows multimedia API that likes to interfere with certain old games, I also know it causes problem for Metal Fatigue, Re-Volt (if you patch it) and most likely others. The solution for this is here:
http://www.geocities.co.jp/Playtown-Domino/8282/
Click the link that says "_inmm.dll Ver. 2.38" and download it, open the zip file and run the installer, let it create the desktop shortcut.
I know it's a scary program, but feel free to virus scan it, what it basically does is patch exes to redirect calls to winmm.dll to itself so it can play the CD audio the proper way old games expect to. Now to get it to work, hit the Windows key and R at the same time to open the run dialog, copy paste and run this:
%programfiles%\_inmm\_inmmcnf.ini
Edit the file so the top of it looks like in the attachement then save the file, now run the desktop shortcut and select the "Patch" tab, use the find function to find the War of the Worlds entry, select it and click Patch.
You will be asked to locate WOW.exe, default location is: %programfiles%\Jeff Wayne's 'The War Of The Worlds'
After you locate it the program will ask you to confirm, do so, don't worry it creates a backup. Now if you have more than two CD drives you need to go to the method tab and choose the correct drive next to CD-DA after MCI. Final step is going to the _inmm.ini tab. There you need to click "CD Tracks", select your correct CD drive after "Audio-track number from" and click Get and then click Ok. Click save and save the resulting _inmm.ini file in your War of the Worlds folder (again, by default: %programfiles%\Jeff Wayne's 'The War Of The Worlds').
Start the game and music should now work (proper track changes and everything), some notes:
1: I did not bother detailing what you need to do to get past security if you're not authorized to write %programfiles%, figure it out yourself.
2: This program also allows you to get rid of the CDs and play CD audio from MP3s, I haven't bothered figuring out how myself.
3: If you get problems with sound effects hold down the Windows and R key at the same time again and write "dxdiag" then click run, select the sound tab and move the slider that has the "Full acceleration" text over it all the way to the left. On Vista you do not need to do this.
