Audio speeding up Issues During Stream + Video Lag

[infinity111Dev]

Hi everyone,


I've been streaming with OBS for about a month now, and I’ve noticed a recurring issue during my streams. At random times, the audio suddenly speeds up, and even when it returns to normal speed, it no longer stays in sync with the video. At the same time, the video also starts to lag .


It's been quite frustrating, and I’m hoping someone can help me identify what’s going wrong.


this is the log file from my last stream:

Any help would be greatly appreciated. Thanks in advance!
