The eac3to demuxing dialog is typically used for BD folder demuxing and for M2TS demuxing, it can also be used to demux other things like mkv, probably not a good idea to change the default mkv demuxer from mkvmerge to eac3to. There is however a decoupled demuxing feature under:

Tools > Advanced > Demux.

eac3to does unlike mkvextract support Core only demuxing, maybe somebody should request it for mkvextract which extracts dtshd even when the dts file extension is used, I don't see how that makes sense.

If you open a mkv file with default settings then you have either dtshd in mkv or you have it demuxed, in both cases the audio processing is a two-step process not directly supported by staxrip. You've two options:

1. Instead of using the GUI audio encoder you can use the CLI audio encoder, this is somehow advanced, ideally for people that like working with command line.

2. You can create an GUI audio profile that does nothing but extracting the core. Directly after you opened the source you can choose this audio profile, go into the audio dialog and choose the option Execute Command Line, while this is processing you can do other things like choosing video filters etc., when extracting completes, right-click the audio track in the main dialog and select the extracted DTS Core file as audio source, then choose your aac or opus profile.
