Hi, I use Windows 10 LTSC 2021 and lately I've discovered Dolby Atmos for Headphones. However, I don't know if my Dolby Atmos is working as intended because LTSC doesn't come with DolbyDecMFT.dll (Media Foundation Dolby Digital Decoders). Note that I actually have no idea if DolbyDecMFT.dll is even needed for Dolby Atmos for Headphones. EDIT: Yes it's needed. Also, try turning off exclusive mode for your headphones if you still have issues. I've seen here that you can add Dolby to LTSC with Dism: Code: dism /Online /Add-Package /PackagePath:C:\1\Multimedia-RestrictedCodecsDolby-Package~31bf3856ad364e35~amd64~~10.0.19041.1.mum dism /Online /Add-Package /PackagePath:C:\2\Multimedia-RestrictedCodecsDolby-WOW64-Package~31bf3856ad364e35~amd64~~10.0.19041.1.mum dism /Online /Add-Package /PackagePath:C:\3\Multimedia-RestrictedCodecsDolby-Package~31bf3856ad364e35~amd64~en-US~10.0.19041.1.mum dism /Online /Add-Package /PackagePath:C:\3\Multimedia-RestrictedCodecsDolby-WOW64-Package~31bf3856ad364e35~amd64~en-US~10.0.19041.1.mum However, as you can see, it will only be version 19041.1. I'm wondering, if you do that, what happens if you update Windows after that? Will Dolby get updated as well, or will it be ignored? Or, will something get corrupted? I'm interested in finding what the simplest way of updating Dolby on LTSC would be, but I need basic understanding of how Windows update works before embarking on that.
No, Most components in the Cumulative Update are devided per Edition updated Dolby components will be skipped for LTSC
I think that until 1607 (LTSB 2016) any package installed is updated by WU, no question asked. Including packages made for servers like the deduplication. After that the packages don't matching the SKU are ignored and left to to the version you installed manually. Keep in mind that DISM and WU are moving targets and constantly evolved, so it's possible that in recent version the situation has changed or may change in the future, leading say to break WU updates altogether.
All right, thank you for the replies. I've been doing a lot of searching on this forum and trying to learn how to do stuff. I think I'm close to success, but I have some questions. I also don't know if the way I did it is the most optimal. 1. I started by using UUP dump to get a build of Win 10 Pro with the latest updates. I extracted the contents of the resulting .iso and mounted the install.wim with DISM. 2. Using AuntyMel's sxs script, I extracted the following six packages from Windows\servicing\Packages: Code: Multimedia-RestrictedCodecsDolby-Package~31bf3856ad364e35~amd64~~10.0.19041.1.mum Multimedia-RestrictedCodecsDolby-WOW64-Package~31bf3856ad364e35~amd64~~10.0.19041.1.mum Multimedia-RestrictedCodecsDolby-Package~31bf3856ad364e35~amd64~en-US~10.0.19041.1.mum Multimedia-RestrictedCodecsDolby-WOW64-Package~31bf3856ad364e35~amd64~en-US~10.0.19041.1.mum Multimedia-RestrictedCodecsDolby-Package~31bf3856ad364e35~amd64~~10.0.19041.2788.mum Multimedia-RestrictedCodecsDolby-WOW64-Package~31bf3856ad364e35~amd64~~10.0.19041.2673.mum 3. The two packages that are up-to-date (2788 & 2673) had 'f' and 'r' folders inside them. I deleted those. The result for four of them was a folder with update.mum, update.cat, two .manifest files and a folder with DolbyDecMFT.dll inside. Example: Code: amd64_microsoft-windows-dolbyatmosdecmft_31bf3856ad364e35_10.0.19041.2788_none_2e2cd060c85b0db6 amd64_microsoft-windows-dolbyatmosdecmft_31bf3856ad364e35_10.0.19041.2788_none_2e2cd060c85b0db6.manifest amd64_multimedia-restrict..ecsdolby-deployment_31bf3856ad364e35_10.0.19041.2788_none_1d1158dcbe37155a.manifest update.cat update.mum Question #1: For the two packages that have "en-US" in their name, I only got three files. Is this normal? What are these en-US packages for anyways? Example: Code: amd64_multimedia-restrict..oyment-languagepack_31bf3856ad364e35_10.0.19041.1_en-us_4be98ec8016556e6.manifest update.cat update.num Question #2: If I want to use cabarc.exe to make .cab files for each, as an example I do this: Code: cabarc.exe -m LZX:21 -r -p N Multimedia-RestrictedCodecsDolby-Package~31bf3856ad364e35~amd64~~10.0.19041.2788.cab *.* However, the resulting .cab file has the DolbyDecMFT.dll pulled out of its folder and placed alongside the other files: Code: amd64_microsoft-windows-dolbyatmosdecmft_31bf3856ad364e35_10.0.19041.2788_none_2e2cd060c85b0db6.manifest amd64_multimedia-restrict..ecsdolby-deployment_31bf3856ad364e35_10.0.19041.2788_none_1d1158dcbe37155a.manifest DolbyDecMFT.dll update.cat update.num Is it supposed to do that?
I cannot figure out how to do this. I downloaded the LCU from here: https://forums.mydigitallife.net/th...h1-22h2-vb_release.80763/page-16#post-1571109, then I just used 7-zip to extract. The .mum and .cat files are there, but DolbyDecMFT.dll is missing, so DISM gives me an error when trying to add the packages.
Code: set KB=kb5025221 mkdir .\%KB% expand.exe -f:*Windows*.cab *%KB%*.msu . >nul expand.exe -f:* *%KB%*.cab %KB% >nul del /f /q *%KB%*.cab 2>nul cd %KB% expand.exe -f:* *Windows*.cab . 1>nul 2>nul expand.exe -f:* *for*.cab . 1>nul 2>nul del /f /q *.cab *.ini toc.xml 2>nul
This is a batch script, right? When I run it, all it does is create a directory called kb5025221 and the only things that are inside are toc.xml, update.cat and update.mum. What am I doing wrong?
It extracted everything, but adding packages with DISM still doesn't work. Inside the folders, there are only "f" and "r" folders with .dll files in them. I don't know what to do with those. This is the DISM command that I use: Code: Dism /Online /Add-Package /PackagePath:E:\kb5025221\Multimedia-RestrictedCodecsDolby-Package~31bf3856ad364e35~amd64~~10.0.19041.2788.mum Dism /Online /Add-Package /PackagePath:E:\kb5025221\Multimedia-RestrictedCodecsDolby-WOW64-Package~31bf3856ad364e35~amd64~~10.0.19041.2673.mum
