Ok. I have installed ALC269-HD-AUDIO and it works. Only thing though the Audio Manager GUI is Simplistic, I'm disappointed . No configuration possible like the VISTA's GUI. Only this dead window: [IMAGE]   About your  #2 above: 2. The Realtek driver within the CAB file should be the same version. But you can test it"...  Since this CAB file contains all the drivers for the T3600, and that I want to update only this audio driver: By just pointing to the file, is the procedure intelligent enough as to find and install only the Realtek driver in this jungle of drivers? [surely I don't want to end up messing with the NVIDIA Drivers for instance].
Subject: Install back, REALTEK_ALC269-HD-AUDIO (On DELL Precision T3600- Win0 Pro 21H1) Last year I bought a refurbished DELL Precision T3600 from a very reliable Non Profit Organization, (Approved Microsoft reseller). Using the functionality SYSPREP, the T3600 was supplied with Windows 10 Pro 21H1. That's all: no Realtek audio or any other Dell Utilities if any. Problem: I'm stuck with Windows 10 audio driver and its "Thin can like sound", no line in recording… Search: A double search (by PC model number and motherboard number) for audio drivers on Dell's site, ended up by giving me the same 2 objects: A) REALTEK_ALC269-HD-AUDIO_VJ0P8_A13_SETUP_ZPE.exe B) T3600-win10-A01-X9M2C.CAB (A mix of all kinds of drivers for the T3600) Don't ask me for the WEB link(s) of these 2, as I have done this search a long time ago Questions: 1) Is REALTEK_ALC269…100% compatible with Windows 10 Pro 21H1 (up-to-date as of Feb 1, 2022)? 2) OR do I have to install ACL269 and then upgrade it with something contained in the CAB file in B) above?    (FRANKLY: I don't believe this is an upgrade). This Cab file is a real jungle. There is an Audio Folder in it. But is doesn't seem to be Realtek stuff. I would not know where to begin with this, if had to use it.
