Massive audio and video delay when capturing Elgato HD60S with OBS

[ZeDiglett]

So OBS just decided it doesn't like my Elgato overnight, it seems. Two days ago, I was using it to capture and display footage from my Switch with no issues, but now, even though I haven't touched any settings and my setup has not changed, I'm suddenly getting ~2 whole seconds of audio/visual delay with OBS specifically. (To be clear, the audio and video are still in sync in OBS, they're just massively delayed compared to what shows up on my TV.) My computer's not lagging, either, as everything is running perfectly except OBS. I tried checking to make sure everything's hooked up correctly (it was), I tried restarting my computer, I even tried a fresh reinstall of OBS, and nothing's changed. For reference, I can still capture games and windows on my computer from OBS perfectly fine, and the Elgato display shows up with no issues in Elgato Game Capture, so the problem is specifically with the Elgato in OBS. Has anyone else had this problem, and does anyone have any idea what might've caused it all of a sudden? Here's the log if it helps. Thanks!
