Question about identifying kext for current hardware

[RedBoo]

I am a beginner to OSx86.

Just installed my desktop with kalyway 10.5.2 and surprisingly most of the hardware works after a fresh installation except audio and sleep mode are not functioning.

I selected most of the hardware driver in the customize option during installation.

 

 

I would like to know the exact driver (kext) which my machine is using and extract it for backup.

for the next installation, i could only install those driver without selecting all.

 

My question is,

1. how do I know which hardware is using which kext file?

2. can i just extract (copy) the current kext file for backup?

 

thank you in advance for your reply.
