Starting a few days ago, I've been having problems with my desktop audio being out of sync with my video (window capture and game capture). Microphone & webcam are fine. The problem occurs in both OBS Studio AND OBS Classic (tested both just to try to figure out where the problem is). It occurs when both live streaming and recording (so it's not an issue on Twitch's end). I checked my Plays.TV client, which automatically records my games, and there's no sound delay in those recordings. So I've concluded this is most likely related to OBS, but I don't know why, or how to fix it.
