Horrible mic distortion :[

Hey, pals. Hopefully this is the right place to post this. I goofed around in Reaper from time to time from about 2013 to 2015 using Windows 7 64 bit and a Blue Yeti USB mic, mostly doing vocals and acoustic guitar into the thing. I went traveling for a few months, came back, updated Reaper, and now my recordings sound really gross. I got ASIO4All and messed with the settings in every way I could think of, to no avail. Pertinent info that I'm not well-informed enough to know how to interpret: Sometimes, if I start a clean project, I can record just fine, but if I change the project settings or turn on the metronome, the recording will go haywire again, even if I undo the changes. If anyone can help me diagnose this, I won't have to record in Audacity and then import everything to Reaper. What a drag that life would be. In case anyone's a static whisperer, I've uploaded a sample of the junky recording here:

Try the soundcloud upload again - linky no worky.

I assume you are on a laptop. Have you tried unplugging the mains adapter from the computer to see if that makes any difference? Sounds like typical cheap crap laptop power issue to me.

Here's that screenshot. I'll try out different computers and stuff asap. That sounds worthwhile. I tried the same computer with a different mic and got the same weirdness.

It's that way because I'm running headphones back out through it. Do you think that could cause issues?
