Q1: I can't hear music, even though the CD-ROM is in the drive.
Q2: When I select "Pick Music," it tells me this option is not available unless the CD-ROM is in the drive, but the CD-ROM is in the drive.
A: The music in the game is standard Redbook CD audio. This means that you can put the Civilization II CD-ROM into any CD player and the music should play just like any regular music CD (except for track 1). In order to hear the CD audio music, you must have the following:
1) The Civilization II CD-ROM in the CD-ROM drive.
2) The proper (and up-to-date) Windows MCI CD audio drivers for your sound card loaded.
3) A CD audio cable connecting your CD drive to your sound card. This last is part of the standard system configuration and is probably present unless you installed your sound card or CD-ROM drive yourself.
If these conditions are satisfied, the music will play. If you do not have the latest sound card drivers, you should contact your sound card manufacturer for an update. Also, there have been reports of other CD programs (such as Microsoft FlexiCD) causing a conflict with the game. In this case, disabling these other programs should fix the problem.
If you're having problems with the music, you may want to check if you can play a regular audio CD on your CD-ROM drive. Open up the Media Player (found in the Accessories program group), make sure CD Audio is in the device list, select it and press "Play." If music plays in the Media Player, you should be able to hear music in Civilization II.
