As part of learning, I also tried to install realtek,but did not go in. When I checked in the device manager, the realtek was not there, but in the programs and features. I tried several times both in safe and normal mode. May be it is not compatible, I am not sure. How about if I want to upgrade my sound drivers
(that you gave it to me). I found the more recent driver
(conexant hermosa 22.214.171.124), I tried to installed it, but said "can not find the device" or something. I appreciate so much if you can help me in my learning.
