Mic quit working due to my mess-up

I have been trying to get Spotify installed on my ONE UP this past weekend and in the process I think I’ve messed up my mic to the point it won’t work. The Spotify client is AMD64-based and the ONE UP is ARM64, but I thought I could configure the keys to work - nope!

So, I’m thinking of using the backups I’ve made to go back to last week and restore the system to when everything worked well. Does that sound acceptable or is there a way to reset the mic?

Thanks!
