    Cannot open audio CD

    I am running Windows 7 Professional on a Dell Inspiron 620 computer. All updates have been applied.

    My problem is that I cannot open my DVD/CD drive when an AUDIO cd is in it. I have no problem opening (and playing) a DVD or data CD.

    The error message I receive when attempting to open AUDIO cd is: "windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item."

    The only way I can open an audio cd is by using Windows Explorer. Attempting to open in My Computer also generates the error message.

    I CAN open an audio cd when in safe mode.

    I have searched and searched, tried many things and am totally stumped! Disabling antivirus and anti-malware has no effect. Microsoft fixit did nothing. Resetting using regsvr32 wmp.dll did nothing.

    I shall appreciate any suggestions or advice in this matter.

    Is this all audio CDs or one?

    As you can open it in Safe Mode then try it in a clean boot as it may be something you have installed which is causing a conflict.

    https://support.microsoft.com/en-us/kb/929135

    The Win 7 section is lower down the page, but try it with just the items under the Startup tab disabled first before you go trouble shooting the non-MS services.

    Here are some other Fixits http://www.free-codecs.com/microsoft...t_download.htm

    This problem exists with all audio cd's, store bought or homemade on this computer.

    I will try the clean boot approach and advise my findings.

    Thanks for the assistance.

    If it works in Safe Mode then presumably something is loading in normal mode that is blocking audio CDs from playing.

    Copy protection? Seems unlikely.

    Have you installed anything sound related lately whether hardware or software/drivers?

    What is in your startup folder?

    What non-MS services are running?

    Do you use WMP to play audio or something else?

    I have performed a clean boot and run the Microsoft Fixits and have no success.

    I am beginning to believe that solving this problem IS rocket science!

    Thanks for the suggestions.

    Are you using iTunes, as that has been known to be problematic at times and would be isolated in Safe Mode.

    I do have ITunes installed but never play music with it. Only use is to backup IPhone and IPad. Looking at processes and services, the only instance shown was ITunes Helper which I ended the task. No effect.

    I have VLC Media Player installed and just tried to open it. I get error message "Your input can't be opened:
    VLC is unable to open the MRL 'dvd:///D:/'. Check the log for details."

    I wonder if there is some connection here.

    I have uninstalled and re-installed Windows Media Player with no difference noted.

    More confusion!!!

    Thanks to all who have responded and to those will in the future.

    I do not find the VLC log in the VLC directory. Where else should I look?

    I suppose the trick now is to understand what that means and why it will only open in Safe Mode, although it shouldn't play because audio is disabled in that mode.

    Can you go Start - type autoplay and press enter then use the dropdown to associate a program with playing audio CDs and is the autoplay box ticked.

    Sudo15, thanks again.

    VLC Media Player is not really an issue for me. I seldom (if ever) use it.

    Windows Media Player is my choice. I am not at all certain that the problem lies with Windows Media Player. To recap: using the desktop icon for the DVD drive I can open and play a DVD. I can open a data cd. I CANNOT open an Audio cd, either commercial or homemade. When making this attempt I receive the error message regarding not having sufficient permissions.

    Autoplay is enabled for all media and devices.

    Windows Media Player is selected as program to open audio cd, enhanced audio cd and audio files.

    Safe mode: Double clicking desktop icon DOES open disk. Of course in safe mode, no sound is heard.

    SFC /scannow - I ran it 3 times and each time it reported corrupted files. Analyzing the CBS log, the file is mmc.exe. There are several instances of this file, and reported error is hash mismatch.

    Workaround: I CAN open the drive using Windows Explorer. I can doubleclick on any one of the cda files and it plays (with Windows Media Player.) I CANNOT open the drive in MY Computer.

    Needless to say, the problem has got me wigged out!

    Thanks again for you assistance.
