The CD that came with the device listed RTL8671B, but it's not on Realtek's website. Instead the manual points you to:

Direct download and the popup window for 1.6.1015.3014
didn't initially work. I ended up needing to right click the link and select Save target as
.
For it to work for me on Windows 10, I unzipped the cab file into a folder and then used Device Manager to look at that folder. Worked like a charm.
Excuse me, what is the latest version for RTL8761B now?
1.6.1015.3020 right?
windows 11 by default itself installs the driver 1.9.1040.1000 but it does not work.
How are these drivers different? do they unlock any possibilities? I used driver 1.6.1015.3018 and when I connect tws headphones to the computer, no sound is output to them, it wheezes and stutters.
