Windows 10: Windows 10 1903 - Audio Line-In won't switch with Default Audio Device

Since upgrading to 1903, my two line-in audio signals won't change whenever I switch the default playback device.

This is my setup:

• Windows 10 Pro 1903 System Build 18362.418
• Realtek ALC1220 onboard audio chipset
• two playback devices (speakers & headphones)
• two line-in devices (front mic used as line-in and back line-in for video game console and second pc audio)
• one usb audio soundcard with only microphone line-in used

Both line-in devices ignore any change to the default playback device up until reboot, whether I do this via script or manually. All other sound is forwarded to the correct audio device, as intended. I've tried three different audio drivers. I've also tested the usb audio soundcard line-in and it's the same result, even though it's a completely different sound device. This is why I'm absolutely certain that this is a Windows issue and not related to drivers. My research led me to this user, who had the exact same issue with the creators update in 2016. Sadly, without any solution for the issue:

Windows 10: Line-in audio no longer honors the default device update anniversary update

Realtek High Definition Audio and Wireless Stereo Headset (Generic USB Audio) are the two output devices.

As I said, I switch between both as the default device depending on whether I want to use my speakers or headset. The Line-In only is guided to the speakers for some reason, regardless if the Wireless Stereo is set as the default audio device.

This worked fine until the Windows 10 Anniversary update.

I checked the drivers, they are all up to date.

EDIT - I should note that Windows audio works fine for both speakers or headset (when changed to default device). It's just the Line-In (which is Line in Realtek High Definition Audio) which doesn't guide to the correct device.

Definitely looks like a bug.
