I guess my post above is lengthy and likely long-winded, and likely to discourage people from reading it. So maybe I'll summarize and simultaneously bump this in hopes of attracting those who may have some insight.

- Have Integrated Realtek HD Audio sound card, running XP3 - Verified it's not a hardware problem. - Device Manager: No unknown devices, all enabled and working properly. But see 'No Audio Device' on Sound panel. - Realtek High Definition Audio Driver. Downloaded v2.28 from Dell and Realtek. I had the same problem with one of my systems one time, I kept installing the driver and after a reboot, it no longer worked. I finally downloaded the driver and each time I booted the computer up one of the first things I would do is click on the driver image I had in a folder and reinstall it for that day.

Ferrari Edition Traffic Assist Pro 7929 Tmc Update To Windows. Brian Azzarello Joker Pdf Converter. Meets Microsoft WLP 3.10 and future WLP audio requirements; WaveRT based audio function driver for Windows Vista; Direct Sound 3D compatible; Multi bands of software equalizer and tool are provided; Microphone Acoustic Echo Cancellation (AEC), Noise Suppression (NS), and Beam Forming (BF).

I thought about the problem for a long time and started to wonder if the driver was too (for lack of a better term ) advanced for my XP, incompatable. I went to the bios manufactures site and downloaded a couple of drivers that were legacy, older. I tried each one going back by one update of the driver at a time, going back each time to the previous driver. The second one I tried (two updates), worked without having any problem. Mine was solved by using a legacy driver that I made sure was for the bios on my system.
