Hi @iliketoDJ999 ,
I have not checked the logs recently, but so far I have not seen audio sync issues with my Blackmagic Intensity Shuttle USB 3 capture card and OBS 27.2.4 (and the Advanced Scene Switcher plugin) and using Blackmagic Desktop Video 12.2.2.
I had to switch from the Blackmagic input source in OBS to the generic "Video Capture Device" and then make use of the WDM device and set its properties to have the "Deactivate when not showing" option enabled. I then scripted the Advanced Scene Switcher plugin to switch to a blank scene for like half a second and then back to the scene that is using the capture card the moment that I either press Start recording or Start streaming.
I have not done longer than 2 hour streams yet, so I can't comment if the audio goes out of sync after many hours...
