Question / Help New ElGato and OBS User Having Sync Issues

Vaughn Whiskey · Oct 22, 2013

Problem: 1st of all, i searched over the forum and did find thing regarding sync issues with OBS and the ElGato but they was dated awhile back. So I am not sure if the issues was fixed or not.

But i just got my ElGato and started using OBS. I used OBS before and know the basics but I have been find sync issues left and right when I am streaming.

It will stay in sync at the start of my stream but a few minutes later, It is out of sync by alot.

Video here - http://www.twitch.tv/vaughnwhiskey/c/3121014

Like I said, I search for fixes and other threads but I was just wondering if anyone else could give me a pointer or direct me to more info on a possible fix. I also think I have OBS setup correctly but I am unsure of that aswell.

Any help would be great!

Troubleshooting: EDIT: I think i didn't have "Use buffering" on. That's what suppose to sort this out correct? Or is it the "mic sync fix hack"?

I tried "use Buffering" on 0, 100 and 200 and it still happens

I bumped my my stream settings from "veryfast" to "superfast" and it seemed to work better. So I assuming the desync might be from my CPU peaking. But my CPU doesn't hit 60-70 when I stream. So that's is abit odd.

Sorry, I was suppose to edit my 1st post not reply to it.. I am half asleep because I spent all night troubleshooting.

Hm, well you do admittedly have two cores, so that could be a factor, but I feel like that shouldn't necessarily be the reason, I don't know. I think I'd have to do some more thorough testing with that type of system to know for sure.

And yea, you do need "use buffering" on for the elgato, it's quite important for syncing.

As a last resort, you can use "audio time offset" to manually adjust the time of the device if needed though.

thanks jim.

most times the audio is fine at the start of the stream, then it desync. wouldn't i have to stop my stream, set the off sync then start my stream?

also, my cpu isn't even hitting 70 when i stream. so wouldn't that be not issue?

I streamed this morning on both veryfast and ultrafast with not issues.

Yea, 2 cores shouldn't be an an issue I think, I was just merely noting it more than anything else. So you got it working? Maybe it was because you weren't using "use buffering". Anyway, if you have any more issues let me know.

Well it worked for abit but it is causing issues again. Phil from ElGato stopped by my stream yesterday and we did some troubleshooting. We was discussing about my computer and I think my i3 2120 is fine enough. I showed him my CPU loads and stuff while streaming and they was below 50. Then he told me to submit a ticket with them because it shouldn't be doing that.

I am not sure what else we can really do but I know the 1st day was perfectly fine but then I had plugin updates twice. I know plugins should cause this issue. I just throwing ideas to the wall.

Besides that, OBS has been a great program and I am happy that i switched over.

Hate to post here again

But the desync happens more when i have "Output audio to desktop" but when I have it set to "Output audio to stream only" the desync doesn't really happen at all. Maybe 100ms at most.

Hey Vaughn, Phil here.

You make an interesting point. We have not tested outputting the audio to desktop, since thats not what most people would do. It seems to be the issue. We do recommend you output the audio directly to the stream. Is there a particular reason it was or you set it to output the audio to desktop?

I was told by a viewer that it had to be set it to Desktop (they also stream with elgato and OBS).. Then I was just messing around with settings and remembered 1st day when I had no issues I had it set to "Output audio to stream only" so I went back and it's pretty much good to go. I do notice a smaller delay but not as noticeable as before.

Vaughn Whiskey · Nov 9, 2013

Is there any chance we can get the "Use Buffering" to be auto set when using an ElGato?

Lain · Nov 10, 2013

It's supposed to be on by default but I think there's a bug with it. I'll make sure it works next version.
