Could you check which value you have in "Mic Mute-LED Mode" mixer
element?  I guess it's "Follow Mute".  If so, change it to "Follow
Capture".

If this works, it means that the driver works as expected but the
problem is only about the default value.  The default value set in the
generic parser is based on other machine's standard (LED on at mic
off), while some machines might expect differently.  On such machines,
we need to set the different value initially in the quirk fixup.
