Hi Dave
You're most welcome. I'm happy to try and help
Here's how I interpret all your data: Your computer has High Definition (HD) Audio (vs the old audio standard that was refered to as
AC97 which was found on older machines). HD Audio is sometimes also referred to as HDA
Windows connects with HD Audio like this:
Windows <====> HD Audio Controller <=====> HD Audio Devices
Windows talks to an HDA controller. In turn, multiple HDA devices can connect to the controller. Windows only "talks" to those HDA devices via the controller.
In Device Manager,
> it's the
HDA Controller that appears under
System Devices (and we see yours there)
> The HDA devices will be listed under
Sound (or sometimes may show up under an
Other Device category. This occurs when no driver found for the HDA sound device)
In your case, only one HDA device is detected and listed under
Sound. That's the internal modem. If there's also an internal HDA device for sound, it must be broken
Therefore, it's not detected and not listed in DevMgr anywhere
So USB is your best (and least expensive) option for sound
