How to Play CDA Files in Windows Media Player

By Jeff Grundy

By default, Windows Media Player plays CD Audio files (CDA) on a computer with the Windows operating system installed. Over time, though, other programs such as CD burning programs or other audio or media applications may change the default program settings for Windows. Even when these programs are no longer in use or installed on the computer, the changed CDA file settings may not allow Media Player to play your audio CDs.Before you can again play CDA files in Windows Media Player, you must reset the default application settings for CD audio files. Fortunately, Windows 7 makes this very easy to do.

Step 1

Click the "Start" button on the Windows 7 taskbar, then click the "Control Panel" tab.

Step 2

Find and click the "Default Programs" link in Control Panel. When the new window opens, click on the "Associate a file type or protocol with a program" option.

Step 3

Wait for Windows to display a list of all known file types on your computer.

Step 4

Scroll down on the list until you find the ".cda" file extension. Highlight the file type by clicking it once.

Step 5

Click on the "Change program..." link in the top left corner of the screen. Wait for Windows to generate a list of programs compatible with the CDA file extension and open a new window.

Step 6

Highlight Windows Media Player in the program list window and click the "OK" button.

Step 7

Click the "Close" button after the list refreshes. Windows Media Player will now be the default player whenever you insert an audio CD into your computer's CD/DVD drive, or when you click on a CDA file in Windows Explorer.
