Dell Optiplex 3070 and Dell Latitude 5400 jack problem

I encountered problem with Dell Optiplex 3070 and Dell Latitude 5400, which couldn't access Microsoft Store (due to GPO), and couldn't download Waves MaxxAudio Pro for Dell 2019, without which using headphones with phone jack connector.

Luckily I managed to solve this problem by downloading Waves .appx file from https://store.rg-adguard.net/ (using url:https://www.microsoft.com/store/apps/9pjppgg8tgvg).

Now I needed to download Appx dependencies. I used this link for that purpose https://github.com/j00sean/SimpleWebView/tree/master/SimpleWebView/AppPackages/SimpleWebView_1.0.0.0_Test/Dependencies.

Then I just ran "Add-AppxPackage -Path "Path\to\File" in Powershell, for every package (Framework, Runtime, VCLibs, Waves).

After connecting jack I was greeted by Waves window, prompting me to select device type.
