How does LDAC work on windows?

[DeyyuZ96]

I've bought today a pair or WH-XB910N and I've noticed they have LDAC. I've conected them to my laptop and I'm not sure LDAC works the same or at all.

(I can't check the Sony Headphones app because it forces my phone to connect to them. My old WH-XB700 could be controlled with the app even when another device was connected without disconnecting the other device and force connecting the phone to them so I could see what codec windows uses)

I've researched that the default Windows driver doesn't support aptX or LDAC. Any information on that?

I've installed the Alternative A2DP Driver but it doesn't do nothing?

The difference I can see from LDAC on Android vs "Sort of LDAC" on Windows is that the Voices are the same but the lows & bass are almost non existent anymore on Windows. (Even when turning on Bass Boost in System>Sounds>More sound settings>Playback>WH-XB910N>Properties)
