Question / Help Sound delay since start of stream

[grester]

Just like topic title says, the sound is delayed since the very beginning of a stream. It's not delaying after an hour like some people complain - yes I've searched the problem - it starts from the beginning. I've look up settings but nothing too clear on what could be causing that. I've neither found anything worth searching through the forum so therefore I'm asking here.
I never had big issues with OBS, it always worked fine - although it sometimes seems that updates instead of improve just worsen itself. I've attached a log file from a long stream I did today. Thanks in advance.

If it's a sound delay with desktop audio, try the "sync desktop audio to video timestamps" in advanced, though that should almost never need to be used.

If it's a sound delay with microphone (which is annoyingly not too uncommon), then you need to use either "Use Mic QPC timestamps" or "mic sync fix hack" in advanced. Usually one or the other does the trick. Stupid options I eventually plan to get rid of, but they work for the time being.

Thanks I'll try both. Unfortunately game sound is also delayed,easy to spot since I've tried in a FPS game.
... Meanwhile ...
I checked the desktop audio thing and turns out I had that activated. Gonna try deactivate and see how it is.

Unfortunately even after deactivating desktop sound, it is still delayed - if activated didn't work I was hoping deactivated could fix but nope so I'm not going to even bother with mic sound delay options.
Any other ideas?

If you're referring to mic delay, then you can manually set sync with it via "mic time offset" in audio settings, to either a positive or negative number.

Desktop delay shouldn't happen otherwise and would most likely be a system or device issue otherwise, especially if that desktop-related audio sync option doesn't work.

As of v0.591b sound is still with delay, could someone send me their twitch stream settings? I don't want to reset to default and do it all over again, I want settings of someone who's assure has no problems doing streams. If it works I'll compare both and send feedback on what could have been the cause for this problem.

I'm having similar issues. Look like a 400ms delay on the audio. I've tried changing the multithreaded optimizations, CFR, and "Force desktop audio" options with no change. The delay is not just the mic or just the desktop, but both of them simultaneously; if you offset the audio with VLC or MPC during playback, they line up perfectly and don't go out of sync.

My scene buffering time had been set to 400ms; tried dropping it as low as possible to see if it made a difference, but it had no effect.

Definitely don't remember this happening before, although I can't recall specifically which version the issue first started in.

Attached is my current OBS settings (profile.ini) as well as the most recent log.

(Edit: also using v0.591b)

"TASCAM Jack (TASCAM US-1800)" -- I've never seen this device before when reading log files, I feel like this may be a cause in this particular instance. In audio settings as an alternative to regular desktop capture, you can also select "Use input device for desktop audio", which will allow you to use "What you hear" or "Stereo mix" optionally as well, if your device has them. Sometimes with certain specialty devices these can help prevent capture issues, though in this case for regular desktop sound, I'm not entirely sure why this problem would be occurring for you.

An alternative solution, you can do is set the "Global audio time offset" in advanced to -400 or something to shift the master audio timing back (though make sure to increase "scene buffering time" to at least 700 preferably)

I've started experiencing this as well. Just started as it had not been in an issue until today. I had optimized my video settings so those are now crystal clear but now the audio is a bit off. I am using an El Gato HD60 and streaming to Twitch.
