Question / Help Webcam and mic become desynced in middle of stream

[Kudai]

When I start streaming, my webcam is in sync with my mic. I put the webcam and mic to have a delay of 1100ms so they can be synced. But later in the stream, my webcam is a little behind the mic audio. I was wondering if anyone can help me fix this issue.Thank you!

1100ms is HUGE

first of all try to use mic timestamps - if not working do some test recordings and sync audio to video manually - have in mind u can have + and - values for sync ;)

Is the 1100ms for capture card is huge delay?

Try to set web camera 'Video Capture Device' Buffering option to Disable.
Also, there were changes in the code (https://github.com/jp9000/obs-studio/commit/d85224bb9b01173b4ceed866482c435681f3f9b1) maybe you need to wait for new release (or build from source/try night builds if any).

dont have experience with capture cards - but with normal direct connect delay of a mic its usually around 20ms
