Hi there,
I have encountered a problem with Windows 10 Version 1809.
When I click on "Configure" on Windows Sound, the speakers configuration will revert to stereo even after I have selected 5.1 speakers or 7.1 speakers.
The issue also causes the sample rate to revert to a lower setting.
For example if I have selected 24bit 96kHz on an audio device, clicking on "Configure" will cause the sample rate to revert to 24bit 48kHz.
When I click on "Configure" and click on "Cancel", the speakers' configuration reverts to stereo.


This is happening on other audio devices as well.
This is a video I took with the onboard audio device:
