Thank you for the reply Bernie.
I gave it another try last night. and I got it working!

By turning on the "Sounds & Notification" (from "Settings") I was able to use the Recorder..! the playback sound was crisp and clear, all the buzzing noise is gone. You can give it a try. Here's what I did.
go to --> Settings --> System --> Sound & Notification
Check off the box beside "Program" and click "OK"
(This is the only box that's checked off, all the other boxes are NOT checked off)
Now go back to sound recorder and give it a try. It should work.
*Note* from my observation this Recording/Mic problem is a software (sound driver) issue. I don't believe there's anything wrong with the Mic itself. Please correct me if i'm wrong.
Lastly, I have a X3i. Cheers!
