Hey everyone, so my microphone (just a pair of earbud put through a splitter to plug into my microphone jack) was working fine up until a faw days ago, but now when I record sound, all I get is uniform, high frequency noise.
I looked through Advanced Linux Sound Architecture/Troubleshooting - ArchWiki but couldn’t find anything that helped, so I’m wondering if someone here can help me figure out what’s going wrong.
Here is my pacmd list-sources:

pulseaudio-ctl v1.67
/usr/bin/pulseaudio-ctl {up,down,mute,mute-input,set,atmost,full-status} [n]
Where up and down adjust volume in ±5 % increments
Where up and down [n] adjust volume in ±n % increments
Where mute toggles the mute status on/off
Where mute-input toggles the input status on/off
Where set set the volume to [n] %
Where atmost only takes effect if current volume is higher than [n]
Where full-status prints volume level, sink and source mute state to stdout
Optionally, redefine an upper threshold in /home/mason/.config/pulseaudio-ctl/config
Volume level : 49 %
Is sink muted : no
Is source muted : no
Detected sink : 6
Detected source : 12
Any help you can provide would be greatly appreciated.
