If you can't get the sound from your audio CDs...

A Hot Topic item on Apple's Discussion Boards deals with problems getting sound from an audio CD played on a Mac.various points are covered. Here is one tidbit that caught my eye (confirming a previous report here at MacFixIt): "Under OS 8, there is a specific issue with Power Macintosh 6100, 7100, and 8100 models, where the Monitors & Sound control panel does not retain this setting through a restart. To deal with this, you can add the Sound control panel via a Custom Install (or it may already be in your Apple Extras folder), and use it to set this option. There is no problem keeping both control panels installed."
