RIGHT click on Start, choose "Explore" from the little menu. When the Explorer window loads, click on "Tools" in the upper left, choose "Folder Options", then click on the "File Types" tab. When that loads, scroll down to the WAV-Wave Sound file extension and click on it once to highlight it. In the lower part of the window, you should see the program that is supposed to open it.. If it isn't currently "Windows Media Player", then click on the "Change" button. When the next window opens, place a CHECK mark in the box that says: "Always use this program to open this file type", then select "Windows Media Player" from the list of programs. When you're done, click on "OK", Apply, OK, etc.
Now navigate to the C\Windows\Media folder and attempt to play the actual .wav files there. Each of the .wav files should have an icon associated with WMP.
Hope this helps.
My computer won't play any wav files. At first I thought it was Yahoo messenger. One day about a year ago, I realized it wasn't playing the alert sounds. I was thinking I had muted them, but my computer won't play any alerts including windows alerts. I checked the sounds in the control panel, and they won't play from there either. They won't play on any media player installed on my computer including windows media player, winamp, anything. Programs scroll through the files as if they are playing, but there is no sound. No error message or anything. Other sound file types play just fine.
Changed the sound card, but no difference. Sound card is used from goodwill. Don't know make or model.
My OS is Microsoft Windows XP Professional 2002. Sound driver is SB Live! Wave Device.
