Despite all the struggling with my setup I couldn't find a fix for it (and I don't have SoundFlower, Audio Hijack, Loopback or any other similar software installed on my Mac).

Meanwhile, two years have passed and I've just learned to live with it but... it would still be nice to have it fixed.

@PLS
Thanks for posting your experiences and I am sorry to read about your problem. Is it the same issue when using headphones connected to the rear jack?

I noticed that in other audio applications, connecting a wired headphone reduced the minimum buffer size of the iMac internal audio device. Using the speaker somehow increases it.

But, BIAB should in both cases be able to calculate the total resulting audio latency and then delay the display by that amount, so audio and video are in sync.
