Audio cuts out, returns delayed

[caomhain]

I'm either streaming game video to YouTube or recording it to my hard drive. Video and audio start synced up. After around an hour, say 50-80 minutes, the game audio will cut out for 3 seconds and then come back 3 seconds delayed. I am not 100% sure, but I do not believe mic audio is delayed. I don't ever observe cpu usage spike above 2%. Watching the audio levels indicators at the end of a stream I see that the level indicators are synced up with the game video, so I believe OBS is receiving the signals synced up (not an input issue?), but I only noticed this in October after a bunch of windows updates "cumulative updates". I have seen plenty of people experiencing audio sync issues, but no one experiencing this cut-out and return delayed issue so I am hoping an expert here will have a solution.

The issue does not occur on the same hardware dual booted into Linux with as close to the same configuration as I can manage, but I prefer to use windows for other workflow reasons.

You can see an example of the issue on the YouTube video here at the 59:17 mark.

I will attach the OBS logs for that stream here as well.

Any help greatly appreciated.

Game DVR should be disabled & there's some sample-rate mismatches that may be contributing to the de-sync. Filters can cause weirdness too. The rest of the log looks OK.

I have disabled Game DVR and set the sample rates to match. That produced no improvement.

After a bit of debugging I've found that the issue is related to the audio source being the automatically added one from the video source. Adding a second audio source in Global Audio Devices settings for the video source audio and using that one as the stream audio fixes the problem. This means that I have to mute the auto added source as it seems to be impossible to remove it completely.

This is an annoying workaround so if I find someplace to report this bug I will.

I have the same issue out of nowhere!
My game audio is out of sync for 2-3 seconds and this happens out of nowhere in the middle of the livestream.

I am so glad I found your post. I will try to do what you did here and I hope this issue won't happen anymore!
