So I found this tiny thing in a bunch of e-waste.
As you can see, the chip is marked as a YMF744B-R. At this point I expected it to be a fake - CMI8738/C3DX repainted as Yamaha. But there's an easy way of checking - Yamaha's drivers won't work with CMI8738/C3DX. So I got the Windows drivers from Phil's Computer Lab. And they worked. Now I'm even more confused. This does not look like a Yamaha YMF744 card. But it is one. It even detects a game/MIDI port, even though the card has none.
Have you ever seen one like this?
I have a similar card with exactly the same profile, but with YMF 754R chip. The card was detected at windows 98 startup and I was able to install the WDM drivers. However there was absolutely no sound output. When trying to install Vxd drivers, the installation would keep looping while detecting legacy audio. So it was stuck in that. Under XP, I was able to install the WDM drivers. However, there was a constant hiss and very noisy to the point of annoying.
Tried moving the speaker output to either line in / mic (as many of these types of cards have mislabelled outputs). Then the speaker out completely stopped working. Not sure what would have gone wrong.
