Sound Input pane
On some computers (those that have an ATAPI CD-ROM and ROM-in-RAM) Audio CDs now always play through regardless of your setting in the Sound Input pane in the Sound control panel. However, if you want to record a CD, you'll have to change the sound input setting to Internal CD.
Speaker Setup
There is an additional option for Speaker Setup that allows you to pick certain speakers and adjust their relative volume.
