Problems were reported with the 3.96 driver if I recall well, which is why 3.95 was chosen instead.

Yes, that is correct.
As soon as the next, bug-free version is released, the newer one will be included.

In DP_Sound_A_wnt5_x86-32_612.7z there is an old driver of Realtek AC'97:

Realtek AC'97 driver from 07/22/2006,5.10.00.6150 [3.91] to 11/23/2006,5.10.00.6200 [3.96]

It is not 3.96 included but 3.95 (build 5.10.00.6190)

Please add again the correct [3.96] version (build 5.10.00.6200):
