Please note that just above the text editor (where you enter a question on the forum) is the following paragraph in RED, and if certain information is not present in your question, our reply may not be very helpful:
Note: If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem.
Note also: You have the option of using the hyperlink ''Edit My Profile'' on the right side of the main page to fill in applicable system information so that it is available.
"Which means", you have not told us what module is used for playing audio nor its version. What if anything has been downloaded since the anomaly began?
Also if I start the computer with the CD in the drive the computer will not boot into windows.
What booting sequence is set in the system BIOS for the system to use?
1. The functions available for "AutoPlay" (view graphics) when inserting a CD or DVD are pictures, music files, video, and mixed content which can be set for automatically, display a prompt to choose an action, or to take no action at all when a specific file type is encountered . If the options appear correctly set, see if running the Microsoft "Autoplay Repair Wizard AutoFix.Exe" will fix the problem. Suggested reading, "Using and Configuring AutoPlay."
2. By using the Scanner and Camera Wizard, users can retrieve images from any of the supported devices installed on the system. The Wizard provides a preview page where the user can select from several scanning options and adjust image settings. It is opened by default when WIA-enabled scanners are activated (a "scan event") and when Plug and Play still digital cameras are connected (a "connect event"). By using the AutoPlay dialog, the Wizard can also be opened when media, such as flash memory cards, which contain image files are inserted into the computer (a "media-insertion event"). Note however, this Wizard is not opened by default for video cameras.
3. Autoplay tab Missing and CD's Don't Autoplay: Since registered components on a system is invoked using the Shell Hardware Detection service and also because non-volume handlers are invoked through it, this service cannot be deactivated. If it is, a user may find they have no access to or can they use either Volume-based or Non-volume-based devices.
a. The primary purpose of Autoplay is to provide a software response to hardware actions initiated by the user on a machine. This feature remained roughly the same from Win95 though W2K and WinME because up until recently there have been very few new scenarios with regard to user-initiated hardware events that could trigger a useful Autoplay action. But lately, with the spread of digital multimedia content (music, graphics, and video) and of the many devices to generate or consume that content, many new scenarios are begging for expansion. In addition to refining the existing Autorun.INF mechanism, audio CD Autoplays, and DVD video Autoplay, support has been added to handle digital music (WMA/MP3), graphics, video, CD burning, video cameras, and other hardware devices.
b. If you've installed software from a CD, you've used an Autorun.INF which the majority of the setup CDs use. The typical user scenario is: a CD is inserted into the CD drive, the setup program runs automatically, and the user simply follows the on-screen instructions generated by the setup software. The Autorun.INF file sample section follows the typical format similar to the following where the first line contains the self-executing Exe file which also contains the text string for an icon. In addition, there could also be value labels of UseAutoPlay (when present, it will take precedence over the open and ShellExecute values and is intended primarily for use with multimedia content for which Autoplay support was added to Windows XP and used to represent the associated drive in the Windows shell) and ShellExecute (works with file associations to run the application associated with the specified file):
c. When determining what actions to suggest or perform in response to an event, Autoplay on WinXP considers the event in conjunction with the various programs registered on a computer. In contrast before, it would always statically run the same application pointed to in the Autorun.INF file or play an Audio CD or DVD movie using the respective default application. Now, two categories of events are handled:
? Volume-based device events are events that affect devices that appear as volumes -- that is, all disk drives accessible via Windows file system APIs. This includes CD drives, removable disk drives, hard disk drives, removable media readers, and mass storage devices. Basically, if it shows up under My Computer with a drive letter, it's a volume-based device.
? Non-volume-based devices include, well, everything else. Specific examples of these devices include digital video cameras and portable music players that do not expose their content as a file system supported by WinXP. This does not mean that all video cameras and portable music players are non-volume devices. For example, newer digital cameras and portable music players that use the USB Mass Storage stack are treated as volume devices since they appear to the system as volumes. Digital camera devices which are non-volume devices get special treatment from Windows. Even though they are non-volume devices, they are handled by the Windows Image Acquisition (WIA) component for backward compatibility reasons.
Note: The article [Q307001] states that by default, the Windows Image Acquisition (WIA) service logs errors to a file named Wiadebug.log in the Windows-folder folder and controlled by settings in the following registry address:
4. The section titled "Autoplay Diagnostic Tools" provides two tools concerning the Shell Hardware Detection service processing for hardware events.
5. The article [Q330135] states that when you insert a CD-ROM into your CD-ROM drive, the AutoPlay or AutoRun feature may not work or is unavailable, but that your CD-ROM drive may work correctly in every other way and may occur if any of the following conditions exist (possible resolutions are discussed for each):
a. A version of Roxio "Easy CD Creator" that is earlier than version 5.02d is installed in your computer.
b. The AutoPlay feature is turned off in the registry:
c. Your CD-ROM drive is using an outdated driver.
d. The CD-ROM drivers are not compatible with Windows XP.
6. The article "The AutoPlay Function Does Not Work and the Current Media Does Not Appear in My Computer When You Insert a CD or DVD (Q817357)" explains that when you insert a CD or DVD into your CD-ROM or DVD-ROM drive, you may experience one or both of the following problems, and the recommends a remedy:
a. The AutoPlay function does not work. Programs or files that you expect to start or open automatically do not start or open when you insert the media into the drive.
b. The CD-ROM or DVD-ROM icon in My Computer is not updated when you change media. For example, if you replace an audio CD with a program installation CD and then open My Computer, the CD-ROM or DVD-ROM icon may still display "Audio CD".
7. If PowerToys "TweakUI" is installed, click the link provided and see if you can ascertain whether the registry settings for AutoPlay are set properly.
8. The following anomalous behavior can occur if "Speech Recognition" is installed in WinXP and has not been correctly configured, [Q313176] :
a. programs may quit, start, or lose and gain focus randomly
b. text in programs may be unreadable
c. the logon screen may appear to be controlled by someone who is remotely connected to the computer
9. Supplemental reading:
a. "AutoPlay Intermittently Does Not Detect Removable Media or Digital Cameras (Q822660)."
b. "Some Access Keys Apply to More Than One Command on the Shortcut Menu for CD-RW Drive (Q303557)."
c. "CD-ROM Does Not Run Automatically After You Insert It into Your CD-ROM or DVD-ROM Drive (Q312475)."
Note: This article does not mention Windows XP, but the system registry could be checked for the presence of the key NoDriveTypeAutoRun!
d. "CD-ROM May Not Run Automatically in Windows XP (Q314855)."
e. "How to Enable or Disable Automatically Running CD-ROMs (Q155217)."
Note: That article does not list WinXP as an operating system for which the article applies.
f. An interesting scenario posted on the forum concerning "RealPlayer."
