I have a newly acquired X20 laptop running Win 2000 and an old Norton 2002. Before dispatch the CD-ROM was playing music OK. Now the CD-Rom appears to play but there is no sound. Control Panel --> Multimedia reveals no sound related hardware. Ditto using IBM PC doctor. Is is likely that vibration in transit loosened the sound connection - in which case I could try getting at it and fixing it. Or is it more likely that there is a driver problem even though there is no sign of hardware in which case how do I reload the Drystal Fusion driverplease :-| ?

Good to see this resolved in the thread. The symptoms described (CD plays but Windows shows no audio device) strongly point to a missing or misinstalled audio driver rather than a loose speaker cable. ran useful checks and confirms a driver fix worked. The short, practical checklist below helps others with the same symptom.

  • Open Device Manager (Start > Settings > Control Panel > System > Hardware > Device Manager). Look under "Sound, video and game controllers" and also for "Unknown devices." Use View -> Show hidden devices and Action -> Scan for hardware changes.
  • If an unknown device appears, open Properties and copy the hardware ID (the VEN/DEV string). Use that exact ID to locate the correct vendor driver instead of guessing by name.
  • If nothing appears at all, check firmware/BIOS for an audio enable/disable option. Only open the case and reseat internal connectors if comfortable and following the service manual.
  • Uninstall any leftover audio entries, reboot, then install the matching driver package with administrator rights. Reboot again and verify the Windows audio service is running.
  • If driver files went missing suddenly, run up-to-date anti-malware scans before reinstalling drivers and keep a current backup or image to restore from if the system integrity is compromised.

If locating a legacy driver proves difficult, a low-cost USB audio adapter that supports the OS can be a quick workaround while hunting the correct package.

For the information of similarly inexperienced users, the problem boiled down to a missing driver. Maybe it was eaten by th eBlackworm virus I also found. The IBM site was of some help, but the driver I downloaded there did not help. I did update th eBIOS and enbedded controller as IBM recommended. I eventually worked out that the driver I needed was not part of the embedded controller but a seperate Crystal Fusion one which I found on the Cirrus Logic site, free of charge, and all is now well.
