Sorry, but if you select an ALSA device, unless that device is
reported as "Analog" (either in the name or description) then AC3 and
DTS checkbox *will* appear.

What does the line at the bottom states when you select that particular device

If you select IEC958, you *will* get the AC3 or DTS checkbox to show,
I can't imagine any circumstances where this wouldn't be true

You shouldn't have to do this.
If you select ALSA:iec958, you will get the AC3 and DTS passthrough
checkbox, they must be activated for you to see the 5.1 output.

If you do not see them when iec958 is selected, then yes, something is broken.

I'd like to see a screen capture if you don't see them, so I can fix
the bug if any
