For the past few days I have been fighting to fix an issue that I have with OBS and the Avermedia Live Gamer Portable. The audio no matter what settings I try will not stay synced over time. I will be completely off by over sec sometimes when I stream for an hour or more.

Here's my log file.

A few other ppl here have that the same problem me included and havent found a fix yet other than quickly disabling the source in obs then activating it again (check and uncheck the box) that fixes the synch untill the next time it happens so u dont have to restart the whole stream,still annoying though lol

This may be a silly question, but did both of you guys update to the newest software AND firmware?
If so, I'm not sure. But I can tell you that I have no issue with audio lag with LGP (I own two of them) and I do 12 hour broadcasts on twitch (look up couch talk with gamer girls). But I can tell you, whenever I have an issue with one of the LGPs (framerate lag/gitter issue, happens randomly) I open up the config settings for the LGP and click "refresh". That solves the issue for me. Have you tried this to see if it solves your audio lag issue? Sometimes audio lag can happen via the ingest server you're using and how you setup your stream settings.

Just a heads up, I'm probably going to buy this device just to diagnose the problem, and I will not delay this for the rewrite if I can figure out what the problem is.

I also own one and have the same issue. The only temporary fix I found was to use Advanced > Force Desktop audio to use video timestamps. This will work for about 20 mins until the audio starts to draft again. I use VAC Kernel to send audio to my headset / streaming pc. Once the audio drifts you need to have a second scene enabled (nothing needs to be in). Just click that scene and go back to your main one to reinitialize the LGP. Since I stream BF4/PS2 I do this after every match or every 10 deaths I have in PS2.

I just got back from a trip, but yes I am fully updated to the newest firmware and software as of last week. I just tried the refresh and I'll run some test in the next few days and find out if that helps. Thanks for the reply though.

And Jim, thank you so much for being so involved with the community and helping users with issues. If you want me to be a test anything let me know!

Jim thanks for buying one of these to try and figure out this audio issue. I am also having this issue with game audio running like a second or 2 behind what is happening on screen after I have casted for about an hour or 2. I posted in another topic about a month or so ago about this. I tried so many different things to try and fix it and nothing worked for me. I also tried uninstalling and reinstalling avermedia drivers and all avermedia software, as well as OBS. Nothing helped. Using the LGP stream Engine software with xsplit I have no problems but I would prefer to use OBS since it's well better.

Are you running your HDMI cables through splitters by chance? Some splitters do goofy stuff to the data stream. Also is your computer at the recommended spec for both OBS and LGP? Did you try lowering the LGP bandwidth quality down from 50MBs? And I assume you're using the newest Avermedia Live streaming bridge software? Sorry for all the questions.. I'm just trying to help because I haven't noticed the issue for myself.

I'm not using any splitters. When I use RECental to livestream everything works fine, no audio drift what so ever. I am using the newest Stream Engine that Avermedia has supplied.

I still don't have one of these devices yet. I haven't really had time to even think about it with other developments as of late, and I still don't know exactly what the problem is. What I do know is that it doesn't happen on other devices, so I feel a little bit suspicious, but I know that my own audio code isn't perfect either, so I can't rule that out. I probably couldn't know for sure until I have the device and have done extensive testing.

I do have the same problem with LGP and OBS.

After many hours of searching, I found one user. He suggested that using the option "Output audio to desktop" in the LGP source properties option would fix the problem. I have tested this solution by streaming under his suggested setting about 3 hours and I can confirm that it does seem to slow down the audio drift problem. While it is not a complete fix, but it does make the stream more watchable. In this stream test, I streamed a bit over 3 hours and the audio only milliseconds behind the video. You can try it out until Jim found a solution.

If you want to see the test stream that I did....here (duration: 3 hours).
http://www.twitch.tv/dirtytubesock/b/493185428

Here is a stream that I did without the "Output audio to desktop" option (duration: 1 hour and 30 mins).
http://www.twitch.tv/dirtytubesock/b/493746122

Skip to the end to see end result of the audio drifting out.
Comparing both streams, the stream with the "Output audio to desktop" took longer (3 hours) for the audio to start drifting out of syn...and only milliseconds behind.

Try the latest Test build, which addresses some sound issues with sync, especially for capture devices.

Thank you so much dodgepong.

Please people, try the 0.60 test builds, and get back to me ASAP. I believe the problem is fixed.

Sorry Jim,

I tried to test stream using 0.60 test build of OBS, but the build doesn't seem to recognize LGP streaming engine as a video capturing device. When I switch back to 0.592 OBS beta, it recognize the stream engine just fine. So at the moment I can't really test the audio drifting problem that people been having with Avermedia LGP on OBS.
