I have been using a Blue Yeti USB Mic under Ubuntu 20.04. It was working great. Then, it suddenly started having issues. I'm not sure when it started. It took a while for me to notice.
The mic will pick up sound, but the volume is not as high as it used to be and I can't seem to increase it. The bigger issue, however, is that the monitoring isn't working. That is, I can't hear myself through the headphones that are connected to the mic. I'm currently more concerned about the monitoring.
The mic itself is OK. It works fine under Windows 10. When I reboot to Ubuntu, monitoring also works for a few seconds and then cuts off.
The mic shows up in the input options. I've tried every input version. I've also checked in pavucontrol and tried every setting I could there. The monitoring shows up as an option (if that is what monitoring is in pavucontrol), but I can't change anything (it is not muted).
I'm a Ubuntu sound noob.
Thank you in advance.
