This is what i found when i googled for this problem, hope this works for you though this registry edit is meant for Windows Media Player 10:
I checked my other machine and found the same behavior described above when previously it did not autoplay a CD when Media Player 10 was open. So I poked around the registry and found that the CDAutoPlay key was set to 1 on both machines under [HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences]. I changed CDAutoPlay to 0 and things are as they were before. Hope this helps others users having the same issue.
In case you have to add it, CDAutoPlay is a DWORD 32-bit value.
How do I change the audio track of a video file in windows media player?
This is done from the Classic Menu.
Unfortunately switching audio tracks is one of those features buried in the new interface. You have to bring up the "classic" menu like so:
Press Ctrl+M or Alt to view the "default menu" (you can also right-click to the right or left of the audio controls, but "show menu bar" does not show in Now Playing mode).
Select "Play" > "Audio and language tracks".
Select the audio track you would like to play.
Press Ctrl+M to remove the menu.

Open WMP, right click on the top bar (Next to the Album playing...), then Help - About Windows Media Player (I have Windows 7 and WMP12)
