! Try going into the control panel (Start>Settings>Control panel or Start>Control Panel depending on how windows is configured) and double click on "Sounds and Audio Devices". A window should pop up. Click on the "Advanced" button (it should open by default to the "Sound" tab), and another window will pop up. Ensure that "CD Audio" isn't muted or turned down. You can (should?) go through all your other settings and double check them.
Alternately, I've tried to play some CD's (newer ones that my son has purchased) in my computer and it won't allow me to play them! I believe it's a copy right issue, where they (the manufacturer/music company) is protecting their music from being illegally shared by those who would copy the music to their hard drives then share it over the internet. Does it do it on all the CD's or just one (or a few)? If it only does it on one or two CD's, then I'd say it's a copy right issue, and not a computer issue.
Let us know how you make out with this issue!!!
War produces veterans, wounded both physically and mentally. They have sacrificed for us.....and it is now our job to help these veterans, as they have already helped us in ways we will never know, in ways that we cannot fathom, and in ways that we take granted every day.
