The System Device 'High Definition Audio Controller' is not affected by uninstall, it has to be deleted manually in Device Manager (if one prefer the PCI-card with yellow exclamation-mark, but can be left to give information about this specific device). I added an uninstall-string to remove everything related tot this driver. Write strings for HDA2.DLL and HDATSR.EXE in SYSTEM.INI/AUTOEXEC.BAT. Copy four files from the folder 'HDAFILES' to their respective directories.ģ.

Recognizing a PCI-Card with yellow exclamation-mark in Device Manager as a HDA-controller and name it as such.Ģ. The INF-file has following functions (quasi Plug&Play):ġ. You can install the driver manually, or you can use following INF-file I wrote for easy testing.

The Win3x HDA-driver is working nice in my WIN98se system, even better than under Windows 3.1 (playback only). I've had a look, and I found a couple of possibles, but none of them seemed to have Windows 10 drivers, which also have to be 64 bit! There are drivers for all three for the old motherboard's AC'97 sound system, so if I could find a card based on that I would have thought it would do the job. I would hope to find a sound card that has drivers for all three operating systems. Would that be possible? It works OK with the graphics cards, Windows XP is the only OS that both cards have drivers for, and they are both installed and seem to coexist (one card is ATI, the other Nvidia needless to say!) It would be great if I could use the PCI plugin card just for the actual listening audio, but use the HD onboard hardware for the microphone and line input on Windows XP and Windows 10. I would want to connect the speakers just to that to avoid having to switch the source when I change operating systems (I do this with my dual graphics cards, using the input switching on a multi-input monitor, but I'd rather not have to do this with the speakers as well!) I could just do without sound on Windows 98, but an alternative might be just to fit a cheap PCI plugin sound card, and use that for Windows 98. I guess this is just too big an ask, even for the geniuses here.
