Working with
Media
??? If you hear the tones, but you can??™t hear music played from an audio
CD, the analog audio cable that typically connects CD drives in desktop
PCs to sound cards might be missing, or plugged into the wrong
connector. (Laptops and newer SATA drives don??™t usually use these
cables.) It??™s a thin cable with small, plastic, three- or four-conductor
plugs, and is found inside your PC case. Unless you??™re using an add-on
sound card, this cable should be plugged into your motherboard; if
there??™s more than one port, try the others until you get sound.
??? If you see the message, ???Failed to play test tone,??? it means there??™s a problem
with the driver. Either it??™s the wrong driver for the device, the driver
isn??™t Vista compatible, or the device itself is not Vista compatible. Solutions
are discussed shortly
If you have more than one audio device, and the current default won??™t produce
any sound, try the others, if possible. For instance, if your add-on
sound card doesn??™t work, but the sound outputs on your motherboard do,
then you know your sound card is the problem.
Trying to get the sound adapter built in to your motherboard
(desktop or laptop) to work? Check your BIOS settings and
make sure the adapter is enabled, as described in Appendix A.
