Question / Help Recent Game Audio Delay issue When Recording

[Timothy Reynolds]

So lately I've had a small game audio delay problem when recording small segments of gameplay. Afew days ago there was no audio delay as seen in these two videos:

However as of Monday I've had the game audio have around a 1-2 second delay, without changing any settings or updating OBS to my knowledge. Delay shown in this video:

The 2015-06-04-1842-25 log file is for the first two videos (had OBS open for a while), and the 2015-06-08-2058-57 log file is for the video with the audio delay (The log file shows two stream starts, but I only uploaded one of the recordings, and deleted the first one)

I would greatly appreciate help with this matter

Scene buffering should be 700ms or greater (700ms is standard now)

dont use sync audio to video time as this will often cause a permanent drift that can't be sync'd properly. when you increase the scene buffering it should be fixed

18:42:32: Bad timestamp detected,
syncing audio to video time

Okay, follow up question, what is the option for the syncing audio time to video time? If it is "Force desktop audio to use video timestamps as a base for audio time" under Advanced I don't have that enabled.

Also just tried increasing scene buffering, to various ms (first 700, then 2000, then 5000), didn't help with the issue at all. Still a 1-2 second audio delay.

Also I believe that error came from the videos that DIDN'T have any audio delay.

Other than trying to find out what, if anythig has changed on your PC (please list if anything has changed), even a driver, windows update, defrag, installed a firewall, installed an in-game overlay, whatever it might be.

have you seen what happens if while you stream, you hit the reinitalize button in the audio settings? does anything change?

I would estimate how long the delay is, and set your scene buffering to a little over that my guess is is 800-1200 (scene buffering 1300?). Then set the global audio time offset so -1200 and see what happens.


I also cant explain to you why this would just now start happening so i'm relying on you to maybe find out what has changed.

I have not installed anything between the days where this started to occur, no updates, no drivers, nor have I done a defrag or anything of the sort. Unless closing OBS and opening it again, or closing the game and playing different games counts as a change then I have no idea what happened to cause it. Could leaving a computer on too long cause such errors?

The audio time offset with the scene buffering worked for the most part thank you, I just need to narrow down the exact delay.

I also tried the "Force desktop audio to use video timestamps as a base for audio time" option on for good measure, and it did sync the audio like in the first two vids I posted (although if it causes problems then the scene buffering plus audio offset should work fine). Maybe I had it on then but accidentally turned it off, or it was just automatically turning it on for some reaosn? I'm not quite sure.

Anyway thank you for the help.

that sync optoin isn't enabled, but sometimes when setting up OBS for the first time, most people just click what they think works without knowing the function. glad it worked but syncing audio to video always bugs me when it can be manually set properly, but again, if it works, awesome.
