Hi there!

I updated to the most recent version of Streamlabs OBS, & I've encountered a problem which was non-existent before the update.

Both of my elgato hd60pro sources produce a crackling that breaks up the audio, no matter what the source is (console, or gaming pc).

I have tried everything I can think of, swapping HDMI cables, restarting both pcs, restarting obs, adding a new source, using custom audio devices...

Any suggestions??

I am having the exact same issue as you are, this issue only appeared after the new update was launched. Also tried similar fixes but to no avail. Just wanted to let you know you are not alone,

I will be watching this thread hoping someone would have a solution

Hey there!


We're investigating a possible issue brought on by our newest updates, if possible, could you please provide me your Elgato capture device settings from inside Streamlabs OBS by right clicking > properties and screenshotting everything within?
Having this issue as well. While capturing my streaming PC's audio (playing music etc) it doesn't do it, but when capturing my cap cards audio it does.. And I finally noticed that Streamlabs OBS is using 100% CPU utilization where as yesterday it was using about 30% while streaming. Capture card is Avermedia C985, settings all default. Here is a screenshot of my settings, let me know if there is anything else I can submit that might help.

Same here, though no crackling but audio drops. With testing x264 settings by recording, regardless if I have video frame drops or not.

Hey again!

If you are using Streamlabs OBS and experiencing this crackling audio issue after the update, please go to Settings --> General and click "Upload Cache to Developer".

Once you have uploaded it, please copy and paste the path it gives you, here. We need this so the devs can take a look and see what is causing the issue. Thank you!

Hey!

Thanks very much for getting that info to me so quickly.

If you click the drop-down at the top do you have a choice that says "Elgato Game Capture HD" ? If you do, try it and see if the same issue happens.

This is the path for my uploaded cache.

Also default settings for my HD60S.

Edit: I've tested the Elgato HD60S in Game Capture HD and there is no audio issues. I would like to reiterate that stream labs obs has been amazing, it was only after the new update did I experience the same issue Marissa is currently facing. Thank you for any help! Will be monitoring the thread from here on out.

Hi!

Anytime!

I actually can't retrieve any connection when I choose the "Elgato Game Capture HD" option. Just the "one moment please..." loading screen from elgato. I'm not sure if this is because I have two PCI elgato devices, but even after adding the source or changing the source and restarting Streamlabs OBS, I get the same screen.

Hey again!

Interesting. I know that the one you have selected is just the base driver that windows gives and it usually has issues.

You always want to use the Elgato Game Capture HD as that is the driver software from Game Capture HD (Elgato Software).

Have you tested with Elgato Software yet? Is the audio still ok from that?

You have two Capture Cards in the same PC?

Hi!

Yes, I have a streaming pc with two capture cards.

I’ve had no issues operating on these settings in the past. I’ve been running a dual pc setup with these settings since January and it’s always worked perfectly. I’ve never been able to get the other Elgato Game Capture HD option to work.

I have already tested the audio in regular OBS studio, with no issues at all. So it’s definitely a problem within the Streamlabs OBS software... I think haha

Hey again!

That is good to know so that we can narrow it down. What version are you on? I have already reported your issue/cache/and screenshot to the developers.

The version is in the top left corner.

Hi! :)

Glad to help! I was troubleshooting all night to narrow down the issue haha.

Additionally, I've also already tried changing my audio frame buffer size within the Game Capture HD software, with no improvements.

I'm running version 0.17.0

I tried reverting back to the previous version, but the software just automatically updates to this version every time.

Hey!

Yeah we are investigating an issue revolving around this and the latest update. I will get back to you as quickly as possible. This may take a little time though since they are actively investigating it.

I appreciate your patience!

Hi!

Thank you for getting back to me so quickly to resolve the issue! I really appreciate it!
Same problem here after the udpate.

I have the same issue no matter what I do. It hurts to have the issue. I've loved streamlabs obs but, since the new update which I don't like it has been cracking my audio and making it hard to stream.
Hey there just chiming in to say I have the exact same problem.

I didn't even notice it because i use the passthrough on my AverMedia c985 to hear the audio so when it was pointed out to me it didn't even occur to me that it would've been something to do with the new update until I unfortunately did everything besides a full windows reinstall haha.

2019-08-21T10:21:24.087Z-gamblord.zip

including notes:
  • audio is fine in passthrough as well as every other type of software that can capture it, it's purely SlOBS that is having this audio crackling problem
  • tried messing around with every setting I possibly could within SlOBS and still nothing at all affected it
I think the new update is using much more CPU than the previous version. In fact, I found that the audio crackling noise was mitigated by closing down all processes not related to the stream and most importantly disabling the preview of my stream and non critical stream features in the live section of Streamlabs. In other words turn off preview stream box by clicking the eye right above the box.

This seems to lower my CPU usage a tad and does indeed help with the audio crackling. It’s still there but it’s much more tolerable and way less noticeable. Not really a solution but it might help anyone in the short term who wants to stream while the Streamlabs team look for a potential fix. I was able to stream last night and there was almost no one commenting on the noise as compared to my last stream where the cracking was bad and every second person kept mentioning it. Hopefully this helps some of you.

I have an 8th generation i5 processor.
I can confirm that audio crackle started with the latest update 0.17.1. I rebooted my machine and the issue was fixed until I restarted Streamlabs.

I also can confirm that my CPU wasn't pegged at 100%. When the issue occurred tonight I closed SLOBS and reopened it and the audio crackle is gone.

Here is a test video that demonstrate the crackle with the alerts inside of SLOBS: https://www.twitch.tv/videos/471027942

While we're on the subject, is there anyway to turn off auto updating? I'd really like to skip versions that are experimental/buggy. I'm sure streamers would agree that having a stable platform and being able to test or revert back to a previous version of SLOBS is critical when trying to run a consistent professional show.

Every time I lose time to issues like this I am one step closer to going back to OBS. If I had a strategy for managing an upgrade process for SLOBS I would be less inclined to move back.

I love SLOBS 99% of the time 🙂 thanks guys for putting in the hard work, because making software is not an easy process!

Hey there!

Unfortunately you cannot disable the auto updates. As Streamlabs OBS is still in it's beta phase, it is important we keep everyone on the same version so that we can pinpoint/troubleshoot/fix any issues that come about.

The specific issue on this thread that was resolved in 17.1 was a capture card audio issue.

This is a different issue that you are experiencing.

Can you please provide a screenshot of Settings --> Audio as well as the name of your audio devices? Headset/Speakers/Etc...
