NotFreestylin, thank you for the screenshots.
Unfortunately, since this is a custom-built device and there is no specific information available about your system model or motherboard manufacturer, I couldn't find the exact audio drivers. As a result, a clean installation of Windows 10 may be necessary (not just a system restore - which you have already attempted a few times before). This process involves downloading a fresh copy of Windows 10, deleting the current operating system, and performing a full installation.
If you're comfortable with this, I can provide step-by-step instructions in my next message. Please make sure to back up all your files before proceeding with the clean installation.
Best regards,
Gunasekar N
