Is there a lossless video capture card that also captures 5.1 audio?

Thanks so much for the update! Disappointing to hear about DD+/Atmos...

I have an Atomos Ninja V which will record 4k/60 HDR and up to 8 channels of audio via HDMI. Once my EZCOO comes tomorrow (I got this one, which has a handy button for setting different EDIDs: https://www.amazon.com/gp/product/B09B7B7BM8 ) I'm going to put that in my HDMI chain and see what kind of recording I can get. I figured I could tell the EZCOO to send the "all audio supported" EDID and was hoping to get the PCM bitstream on channels 1 & 2, but it sounds like that'll only be for DD 5.1 and below.

But, what if I have my device do the decoding and send 5.1 or 7.1 PCM over HDMI? Then I (should) get all 8 channels into the Ninja V. Not sure how that works with Atmos though. I haven't found a good layman's description of how it works, it sounds like it's just metadata, but would that be encoded into the 7.1 stream somehow, and would be reflected in an 8-channel recording? But even if that metadata was there, I'm guessing that on playback it won't trigger the receiver to decode it properly, it just thinks its getting PCM and so just sends that straight to the speakers.

I'm looking to cap'ture the Dolby Digital audio signal from a SKY Q using the Blackmagic Ultrastudio Mini 4K.
The EZCOO listed here is no longer available.
I got another model,

but still can't convert the audio from Dolby Digital to LPCM in order to capture it.

Connections are
The HDMI signal coming out of the SkyQ enters the EZCOO converter input.
The EZCOO's output signal goes into the Blackmagick's input, but I only get crackling audio.

Any suggestion?

Better start your own, new post, this is already a post from another user, things could get confusing otherwise...
