I would start with lspci, lsusb and possibly dmidecode.

Anything which says "audio" or "video" in the output is a good start :)

In that case I would boot into a (live?) version of Ubuntu and run:

    lsusb
    lspci
    lsmod

That last command will tell you which kernel modules have been loaded in order
to support the various hardware devices.

Possibly - it's worth a try, to see whether it does a better job with less
work than persuading Chimaera.

Yes, for example http://devuan.bardia.tech/devuan_daedalus/installer-iso/

Feel free to post the output of lsusb and lspci here (best from Ubuntu, since
it seems really to know what the things are) in case anyone recognises devices
and can point you further in a helpful direction.
