It captures both AC3 and DTS from HDMI using a BlackMagic Intensity Pro PCIE card (non 4K version). You need to use their native SDK and some custom code to handle compressed audio. I'm not sure if any publicly available capture apps do this. Depending on the player you're capturing, you may also need to spoof the EDID because the MBIP only reports stereo PCM as supported and some devices will not send out AC3/DTS when they see that. Using my software, I get timestamps on each captured video and audio frame and can compare those to the presentation timestamps stored inside the original file being played. You need to understand the MPEG file formats and headers to do this manually. It's a bit tedious and time consuming to do this so it's been a while since I've done this for a recent Kodi build. It's possible things have regressed since version 14 I tested.
I assumed you would be doing something like this. I didn't realize that Blackmagic SDK allowed compressed audio capture. Actually, I haven't really looked into the SDK although I have the 4K Extreme 12G card. The scope of my test was only to find out whether were differences between the different Kodi builds. A lot has changed in Kodi since v14.0!

I'm not sure it does - technically (will have to ask a few friends who write some commercial-quality code for them)... The BlackMagic SDK does allow for quite a lot of control I understand.
