After several attempted re-installs and upgrades of drivers for each device (my erroneously diagnosing the problem as having to do with outdated Realtek audio drivers), he found a couple of links that provided a way out that didn't involve re-imaging the machine. Initially, Device Manager barked "Code 39" when we examined each audio device (Realtek HD, a USB mic and NVIDIA card audio). After plugging it in he obediently rebooted when prompted by the O/S.įor the next couple of hours we struggled mightily with the system to get audio working again.
