Question / Help Audio out of sync and skipping when trying to use Elgato HD

I'm new to streaming and was basically following a few tutorials on how to set up my elgato and obs for streaming on twitch. I'm experiencing audio skips and delays and have tried countless times to get these two programs to work together. I'm at a loss and now turn to you guys for some more experienced help. When I opened up task manager during my stream, my cpu was sitting around 40% I'm not seeing any stress on my PC. My video is smooth and looks great. I'm just having audio problems.

Here is my log file

Code: 
Elgato Game Capture: force buffering with 1 msec
in the properties of the elgato "video capture device", 1ms buffer is way to small. either turn off the buffer or raise it to 1000ms (aka 1 second).
Code: 
Syncing audio to video time (WARNING: you should
not be doing this if you are just having webcam desync,
that's a separate issue
^dont sync audio to video, this is probably what is causing the issues.

Code: 
Interface: Realtek RTL8192CE Wireless LAN 802.11n PCI-E NIC (802.11, 144 mbps)

dont stream over wireless. wireless causes issues of its own, mainly stream stability, studdering, and/or stalling at times since all wireless travels over the same medium/frequency.
 
if you are using obs .65, it introduced an audio delay on elgato hardware because elgato still needs to update their drivers. here is a quote from the other thread, you will need to get the drivers from shrimp before they officially roll out the drivers. BTW this fixed my audio delay issue.

Hey guys. There's a user by the name of LtRoyalShrimp on here that PM'ed me regarding the recent OBS update and the out of sync sound. I'm not sure that i'm able to post a link to the Beta drivers as they're nowhere to be seen on Elgato's own website but the driver GameCaptureSetup_2.30.6.1006_beta has fixed all sound and sync issues. It's also a lot more responsive for me than the old one I used from their website but unfortunately still no x64 support. These are my Elgato/OBS settings:

Hopefully LtRoyalShrimp will see this topic and post more info in here to help anyone with issues out.

Good catch.
 
Ok, I'm using a LAN cable now, I'm still stuck with Elgato forced buffering 1 msec. I checked the properties section and couldn't find anything that would allow me to make changes. I know where youre talking about, I saw a picture of the properties on twitch. I'm missing that section.

Syncing audio to video time, Im not sure if I did this right, but I went into advanced settings and under audio, I changed it from 1500msec to 0. I believe that took care of the warning.

However, I still have audio skips and desyncs. I'm going to try to get the beta drivers that are listed below this post. If there is something that still looks wrong, please let me know. Here is an updated file log:

I am having the very same audio skipping issues. No problems when streaming from the Game Capture HD software, but when using OBS the audio is choppy. Video looks great and streams great.
I attempted to output the audio to desktop instead of to the stream, it sounds way better, but instead of choppy it has random crackles in the audio.

If these beta drivers will fix my problem i would love a copy of them.

Yeah uncheck "force desktop audio to use video timestamps as a base for audio time" right above the global audio sync. just in case, dont use "use mic QPC timestamps" either


I hope those beta drivers work for you all. its a pain hearing that you guys cant use your elgato properly.
 
I started streaming with OBS and an el gato HD around a month ago and have had nothing but trouble from it. The audio desync appears almost random. Sometimes it's just a bit off and consistent and then the next time it will start correctly and gradually get worse.
I had similar problems when I used to record using an HD pvr. I would always have to go back and resync the audio. Even that was not an exact science.
I fixed my old problem by uninstalling the realtek drivers on my rig. I have a feeling if I do the same this time it may resolve the problem. Only thing is, I need some of the features that come with those drivers. I can honestly say all this is taking the fun out of streaming for me and I don't want to have to get a capture card as this was a gift.

Sorry if this is all unrelated. Back on topic, I was just wondering if anyone else was using realtek drivers and integrated sound while having this issue.

Read a quote from @LtRoyalShrimp: and the info he has in it. the quote wasn't for you, but I think you can get some good advice from his advice. Also, make sure you are using the newest release of the elgato software.

Since the desync happens on everything, we need to go step by step.

So, lets begin:

  • In the logs, the C920's audio source is the Blue Yeti
    • Why? You should disable the C920's audio since you won't be using it
  • The C920's audio timestamps are behind
    • This could be due to a number of issues.
    • Please plug the C920 into a USB port, AS FAR AWAY as possible from the Game Capture HD60! They are known to cause issues when connected on the same root hub due to bandwidth competition
    • Plug the C920 as well as the HD60 into a free USB 2.0 port.
    • Another C920 tip: Don't run it at 1080p. Set the C920 resolution in the properties to 720p, or even lower. This reduces bandwidth and reduces other known issues.
  • You seem to have posted an incomplete log, as I cannot see any CPU information, but
    • You have quite a lot of frame lag (4%) and 20%(!) frame duplication! These are very high numbers. Your CPU seems to not be able to handle the X264 preset, and high CPU usage can cause desync issues.
    • Try lowering the X264 preset and doing all the above suggestions.
Once you have read all this and tried it all, let me know if the issues still persist.
