The filter option Window you described cannot change channels, only allows for OK/Apply if 2 channel selected, but if I select the needed 8, window stays open even if OK is pressed.
Official API term to capture all audio channels for DeckLink is "EmbeddedAllChannels", if that helps.
I can't find that term in the SDK docs, where do you get that info from? google suggests that term is something to do with https://www.vmix.com/

You are correct, I mixed it up, I am currently playing it with vmix and only that option gives all channels.
Not that you need it, but here is the DeckLink SDK manual:
https://documents.blackmagicdesign.com/UserManuals/DeckLinkSDKManual.pdf?_v=1734595211000

vmix doesn't have flexibility of Rendering and filters, that is why I would like to go back to MediaCenter.
Good news is that 2 channels it captures are L/R, not a downmix, which means others are just offset to it.

Also, make sure you are using Yaobing's latest DLL for this.  You will need to manually copy it into your MC Program directory (eg C:\Program Files\J River\Media Center 33).

new DLL

Hopefully this will do something for HDR.

Regarding the upside-down video, I might have specified the media type wrong. I will need to figure out something else.
