Hello Everybody.
I have annoying issues with my webcam and microphone sync.

I have using - streaming with Logitech C270 (webcam) and Samson G-Track (microphone).
When i'm starting livestream, everything is ok but for longer more the webcam and microphone are desync i see on OBS the delay between saying something to microphone and moving the "microphone volume bar" (receiving my voice in obs).
The delay depends on how longer i'm streaming. At all the maximum delay (between webcame and mic) what i've noticed is 3 seconds after 10-15 minutes livestreaming :/

It can be Procesor fault or USB (2.0 or something)?
Anyone can help me and fix it when it's possible?
I've tried to set delay on webcam (buffer time on webcam) but it's not working ;/
The delay it's only between webcam and microphone, game and video(from game) are sync.

Here's my log:

Re: Random Desync Webcam and Microphone depends on live time

You can try "Use Mic QPC timestamps" in Advanced, and then turn the Scene Buffering time up to 700 or higher, also in Advanced.

Re: Random Desync Webcam and Microphone depends on live time

If i set Use Mic Timestamps my microphone is turning off on OBS after 5 minutes from start streaming.
My mic: Samson G-Track

But if i have this mic timestamps on i feel sync with my webcam and microphone = good but my microphone is turning off in OBS as I said - after 5 minutes from start streaming.

Anyone can handle this ? :(

Re: Random Desync Webcam and Microphone depends on live time

Did you raise the scene buffering time as well? If you don't raise it to at least 700, it will mute your mic after a while. You may need to turn it up even higher than 700

Re: Random Desync Webcam and Microphone depends on live time

Yep i've tried increasing the buffer time to 700/1200 and 2000, after few minutes my Microphone is going off automatically :/

And i'm noticed the Mic QMP Timestamps are perfect way to sync my mic and webcam but the f*cking mic mute is annoying :/

Re: Random Desync Webcam and Microphone depends on live time

Oh, you enabled "Force desktop audio to use video timestamps" for some reason. You shouldn't have done that. Disable that option and things should start working better.
