Lenovo g550 audio (microphone) driver issue redux from 2013

LIke the 2013 post somehow the audio drivers (microsoft) for the microPHONE got putzed.
I hear Conexant drivers are loathesome.
Can I just -copy- (five: hdaudio, sysfx, WMAL...., etc.) drivers from another lenovo or
do I also need a .INF to add parms to the registry (a 'real' install)
automagically and would you suggest MS as a good source?
OR
uninstall all the audio bits and let win 7 sort it out.
thanks, happy holidays, be safe, and ain't we glad COVID doesn't affect software as well...
