Constant microphone noise

Hello, everyone, first post here.

I got a headset, and I have been trying to get rid of the noise it had, a permanent buzz. I could still listen to anything, but the buzz was just as loud as everything I played.

After scrambling a bit through posts, I added the following to /boot/loader.conf


and the following to /usr/local/etc/pulse/daemon.conf:

default-fragments = 8
default-fragment-size-msec = 5

That made the $mixer igain 0 command mute just the noise, whereas before it muted all sound.

Recording with the microphone still picks up just buzz, nothing else.

Is there anything I can do to make the buzzing go away and make the microphone usable?

This is the output of $cat /dev/sndstat

So I tested this headset on another laptop and desktop, on linux mint, windows 8.1 and 10, and it's just a broken microphone - I was hesitant about that, because I had just bought it.

I'll get it replaced today, that's all (had a warranty, nicely enough).
