I have accidentally deleted the mac default sound driver and now I can not use my default speaker and microphone
Emily Wong
Can someone please send me a copy of the default sound folder?
I believe it is in the folder /Library/Audio/Plug-Ins/HAL
What I currently have is this:
My current Sound Output and Sound Input, and it is missing the default
Can someone help me identify which driver im missing and perhaps a copy of it?

First, check in Apps/Utilities/Audio Midi Setup & post a pic of your Audio setup page, just for confirmation.
Then boot to Recovery ( Cmd ⌘ R at boot) & re-install the OS. If you do this directly from the onboard recovery straight over the existing OS it will not affect your data, though you should always have a backup anyway.
That should reinstate any missing or corrupted Apple components.
I think you're missing the BridgeAudioSP.driver. The reinstall should put it back.
