Hi Currently using OBS on Ubuntu Studio, I've got 3 cameras coming in via capture hdmi capture cards and the video's are out of sync so I spent time setting Video Delay (Async) for each video source and get the videos in sync. I then spent time setting Sync Offset on the audio source to get everything aligned.

I would then record/stream using these settings and all would be fine, but the next time I come to use the obs even checking that all the settings where there the cameras and audio would be out of sync with each other and would need configuring again.

I even tried getting everything setup recorded with it for 10 -15 min and then exiting and rebooting the system and after resetting with out making any changes the cameras and audio will be out of sync again.

I have check that OBS and OS are upto date.

Is the expected behaviour and if not what could be causing the differences in offset even when not changing any settings anywhere.
