Question / Help Sound Delay | OBS + Music Player

Kazu · Jan 14, 2014

Hey Guys,

As soon as I run Foobar or Winamp in combination with OBS my sound gets delayed.

If I stop the music the music stops after 3-4 seconds.
Same goes for games e.g. League of Legends. If someone pings the sound of the ping comes 3-4 after the ping.

The Task-Manager shows CPU: ~60% RAM: ~60%.
So my CPU can't be the problem. It's an Intel i5-3570K with 8GB DDR3 1600MHz Corsair Vengeance.

Does anybody knows why this happens to me?
It began after an update of OBS.

~EDIT~
Here's the log:

For certain hardware components, you might have to use the "Sync audio to video timestamps" in advanced settings. Let me know if that works for you, also thank you for posting your log so I can make note of your hardware.

Kazu · Jan 15, 2014

Thanks for your reply.

I already did that but it didnt helped. I also tried the latest beta build as seen in the log.
Nothing seems to work for me.

~EDIT~
I do not have this problem without any music player, but a stream without background music can be quiet boring so I don't wan't to stream without music.

mrbrinks · Jan 15, 2014

Try delaying your sources to sync with the music maybe? Since you can't un-delay...

Kazu · Jan 15, 2014

What do you mean?
The overall sound gets delayed after a while. Music, Game, Browser or to be precise the whole Windows sound output.

~EDIT~
Apparently this problem occurs if I have a music programm open at the same time.
If I have a web player open, this problem does not occur.

~EDIT2~
Nope, still occurs with a web player.

Do you have a mix of sounds that are in sync and sounds that are not in sync? Or is all audio on your stream delayed? Is it only your desktop audio device, or your mic too (If you use a mic)? Do you hear the sound delayed on your end, or is it only delayed on stream?

Can you link to a video of the issue?

Kazu · Jan 16, 2014

No, every sound is out of sync. Music, Game, Teamspeak etc. No, my mic works perfectly fine. It's both delayed. Stream and my end.

I do not have a video of it, but I make sure to save it as soon as it happens again or as soon as I'm live again :D

dodgepong · Jan 16, 2014

So on your computer, if you are listening to your own computer and not the stream, if you press play on Foobar or Winamp, the music doesn't start playing in your speakers for 3-4 seconds? That seems very odd...

Kazu · Jan 16, 2014

Yes, the music starts after 3-4 seconds after I press play.

I do not know where it comes from but it is really annoying :D

dodgepong · Jan 16, 2014

And this only happens when OBS is streaming? If OBS isn't streaming, your audio is normal and when you play music, you hear it start right away?

Kazu · Jan 16, 2014

Yes, this only happens during streams. Sometimes directly after I start the stream, sometimes 10 to 15 minutes later.

dodgepong · Jan 16, 2014

Oh, I see you're using a Behringer audio device? Can you tell me more about your audio device setup?

Kazu · Jan 16, 2014

I've got a Behringer XENYX 1024USB plugged in via USB Cable to the PC.
Headphones are plugged in to the mixer, same goes for my t.bone SC1100.

Lain · Jan 17, 2014

You didn't modify the "Global audio time offset" from 0 did you? It should always be at 0 unless specifically needed to fix some certain problem. If you need though you can set it to a negative value to offset your sync issue, but you -must- increase your "scene buffering time" to accommodate the negative value. If you need to use -3000 or something, use 3100 for scene buffering time for example.

Kazu · Jan 17, 2014

No, I haven't changed it.

Apparently the bug has nothing to do with music or not.
It just happened now without having a music player playing music.

http://www.hitbox.tv/video/88283

The delay in the video is shorter than the delay I'm hearing.

I also deinstalled obs and reinstalled it, so that all plugins are gone.
But the bug still occurs.

So it has nothing to with plugins.
OBS is working perfectly fine for my friends.
I do not understand this.

dodgepong · Jan 17, 2014

If it's affecting playback on your computer itself, it has to be some issue with the USB audio device itself. I'm not sure what would be going on to make it do that. Do you have the hardware to hook up the output of the mixer via analog through the line-in input on your sound card, and just listen to the Phones output on the board instead of the USB output?

I have a Behringer board myself, but I avoid using the USB devices, because USB audio devices can cause weird problems like these sometimes.

Kazu · Jan 17, 2014

Sure, I could plug my headphone into the pc via jack.

I will try this and if the bug appears again, I will let you know.
But why is the delay in the stream too, if my mixer would be the problem?
I mean, the windows sound gets send to my mixer, so it should be in sync until the mixer sends it my headphones.
So the sound should be in sync for OBS too, because OBS does not depend on my mixer.

dodgepong · Jan 17, 2014

You're using the mixer as a USB output device, though. Sound is coming from the Behringer into your computer alright, but you're also outputting back out to the mixer (which i think is somewhat unusual) and that might be part of the cause. OBS is taking whatever is output to the USB mixer device and streaming that.

It's kind of weird...you're outputting from the mixer into the computer, but then sending audio from your computer back into the mixer...seems like there's a weird loop that could be happening there, and maybe OBS is getting in the way of it somehow.

Kazu · Jan 17, 2014

I'm using the mixer for months now, but the bug appeared 2 weeks ago.

Before the update, everything worked perfectly fine but it seems like there is no error in the log.
I set the preset to "veryfast" and will look if its my cpu who's behind. If the bug appears, I will plug my headphones via jack into my pc.

If that doesnt help either I will reinstall windows and install only necessary things.
Maybe it has something to do with a broken driver.

Setting up windows doesn't take that long and is mostly the best solution, because the system gets cleaned up ^^
