Hi all, my fault: I broke down the windows 7 (Entreprise) sound sytem. It was done by removing a "free" soft to capture sound. It was full of xxxware and a pain to remove, and I did too much. The facts: - All devices in the "Audio & video controlers" (my release is not in english so I try to translate) are marked. A "(!)". - Even if I try to reinstall the sound driver (Realtek) it fails - Many tests and checks have been done: "chkdsk / f", SFC /scannow", ... The SSD is said to be in fine shape and the NTFS structure said to be sane. Do you have any idea of how I could get the sound fixed, as I can't go to a restore point, and have programs installed so I can't reinstall/upgrade to Win10 without losing them ? Thank you for reading this.
