This is on Arch Linux w/Steam and there's a workaround, so I'm posting only because it raises an odd question, plus, entertainment value, and maybe it'll jog a memory someday, who knows?
Sound effects but not music are distorted, and then echoed once, quieter, after two seconds.
I was going to record it to show the nature of it, so I installed obs-studio and made a movie. The movie recorded the correct sounds, even though I heard the distorted and echoed ones.
I tried shutting off the microphone, thinking that might be it. No difference. I tried the `padsp` method from an earlier report, no difference.
I plugged in a headset. That fixed it. I can switch the distortions and echo on and off by switching outputs, with or without a mic connected.
So far as I can tell, this happens only with factorio.
[0.12.33] sound effect distortion and echo
Re: [0.12.33] sound effect distortion and echo
Does it only happen when recording with OBS? If so it could be some weird interaction between OBS and Factorio...
Edit: Never mind, upon re-reading I see you only installed OBS _after_ you had the issue.

Re: [0.12.33] sound effect distortion and echo
This affects _all_ sound (including factorio's music, I just didn't notice it before), including for instance system beeps from an xterm ringing the terminal bell while factorio's running.
Something about factorio is rewiring pulseaudio's streams. I did a pacmd dump and later a pacmd list before and after starting factorio, here's the diffs. It seems it's explicitly activating the monitor and configuring max latency on index 0 -- I checked, it's doing that even when that's not the default or active card for anything.

Re: [0.12.33] sound effect distortion and echo
This has gone away, by the way. In the interim I've switched from an AMD card to a Nvidia, using the vendor HDMI audio, so it could easily have been a driver issue.
