My Lenovo T495 laptop has dual microphone inputs and I am struggling to activate microphone noise-cancellation.
I have read Section 6.4 in the Arch Wiki but I cannot understand Pulse Audio Control because my knowledge of Linux is very basic. I noticed a line of text that seemed to suggest Echo-Cancellation was present and could be enabled. But how to do this is a mystery to me.
I would be grateful for any helpful comment.
