Determine the DCH (UAD) Realtek driver needed for your Audio

MarionGrandJ said:

DDelo, I appreciate the automation offered by your script to identify parts of Realtek UAD driver's stack we can update.
But your script doesn't work without modifications in non-English version of Windows or more specifically when using non-English version of dism.exe.
A simple, but brittle, modification would be to add the option "/English" to each call to dism.exe in your script.
But I would like to go further by eliminating the output hijacking of dism.exe completely from your script and by replacing them with equivalent powershell command (like the Get-WindowsDriver cmdlet). Is there any script repository where I could submit pull request or open an issue and propose my solution?
Thank you again for your work.

Thanks a lot for the recommendation, regarding DISM calls. I will investigate it.

The reason for using DISM in place of PowerShell's Get-WindowsDriver is purely performance. Get-WindowsDrive is much easier to use, but is very slow compared to DISM, with which I have to parse to get the strings I want.

And no, there is no repository for the scripts. I create them for own use and the ones I believe that can be helpful to others, I just post them in the respective thread in TenForums.

Does this mean I need to get the Realtek drivers somewhere else?

What do you mean by "somewhere else".
Like where?

You can update your audio driver in several ways:

1. From Asus support page, if they have an updated one
2. From Mokichu drivers (as he's an Asus expert)
3. From Microsoft Update Catalogue, by downloading the basic driver + the Software Components + the DTS Audio Effects Component, following this tutorial.

Sorry my bad, I just meant the basic driver from MUC. Since the script only found the DTS SoftwareComponent it sounds like Mokichu's ROG page is the place to be Please correct my understanding, these fancy new software components are a bit complicated. Thank you for your help, your thread was very helpful!

Thanks a lot for your kind words and I'm glad you found this useful.

The purpose of the software components is to take off functionality from the base driver and allow Microsoft to easily test only the driver.
As you know there are numerous audio implementations around the world, which makes very hard to test compatibility of the driver, when everything was bundled in one package (the legacy HDA driver).
Nowadays, with the DCH driver, they just test the driver for any incompatibilities and that's all. The rest of the functionality is on the different software components, which may or may not be updated at the same time with the basic driver, which is not mandatory, i.e. they can be dated at a later time.

PowerShell script of Option 1 has been updated.

Thanks a lot for the test Cliff..
It looks good to me....what do you think?

A reminder to UAD Avolute/Nahimic users, the higher driver number is not what to go by.
Some versions are for motherboards, some for laptops, and there is also difference in manufactures.
Best for Nahimic to just let the store update your 3rd party app like SonicStudio 3 for ROG owners.
