Solved suddenly unable to Play Music Files on Windows 7 PC

Specs: Windows 7 Sp1, 2.8 GHz / 3326 MB
For some reason, I am suddenly unable to play music files (mp3s and .wavs) in any player application, including WMP and GOM Player. I suspect some kind of codec deficiency, but I'm not sure how to pinpoint the problem. Any advice on where to look? Thanks.

Not sure where Quartz.dll comes into all this and I now suspect it is nothing to do with it. The problem appears to be related to WMP itself. There is a MS FixIt to repair WMP (just click a button) here if you care to try it:
https://support2.microsoft.com/mats...

Alternatives if that doesn't sort it out:
1. Associate your Mp3s and .Wavs with QuickTime (can help if needed).
2. Get VLC and associate the above files with that instead.

I'm not really a QuickTime fan but if you just want to play those files then 1 above should do it without downloading and installing another player.

Always pop back and let us know the outcome - thanks

Any errors showing in "Device Manager > Sound, video and game controllers"?

Is sound working otherwise, with saved videos for example?

No, no errors. Sound is working- I can playback music on websites, system sounds work.

Additional Info-

When WMP fails to play the file, I can click on a "Web Help" link that identifies the problem as Error C00D11B1. Looking around online, I see info about re-registering "quartz.dll," but doing so has no effect on my issue.

Quartz.dll appears to be a DirectX file. Not sure I can see the connection but you could type dxdiag in the Run box (hit Enter) and see if all looks good there, or see if the update (win 7) will run in:

If push comes to shove try VLC free player - it will handle those and a lot more besides:

I don't see any probs there. However, I just discovered that my audio files WILL run on Quicktime. Does that indicate anything?
