New acer computers should come with realtek audio console app to configure the laptop's audio driver. It may have additional premium audio software (like DTS or Dolby or Waves MaxxAudio app). The only Realtek feature I can think of is the karaoke feature where the computer can strip the singing voice off the song so that you have just the background music for you to sing. Or that laptops may have configuration tools to pick near field vs far field mics. Far field mics are generally for things like cortana or google assistance to listen to your voice 10 feet away asking for the weather instead of 2 feet away from the webcam.

Some laptops can let you pick near field mic when you are sitting down doing a webcam meeting or pick far field mic when you are talking and writing on the blackboard 10 feet away.
Many of these tutorials are for music lessons (i.e. 1 to 1 piano lessons), so they are geared towards the free zoom account.
If you are a church broadcasting things, then either you have a paid zoom account --- which paid accounts have additional features that these tutorials would not touched upon. I am not even sure whether broadcasting church service should use zoom in the first place (i.e. it's more or less designed for 2 way teleconference). May be easier to do a youtube live broadcast. Don't have a clue.
Ask other churches what they are doing.
