and

ln -s ~/.kodi/addons/inputstream.adaptive/lib/libssd_wv.so ~/.kodi/cdm/

Why are you doing this?

It's in the instructions for "LibreELEC (Krypton) v7.90.009 ALPHA".
But it doesn't matter... seems the problem is elsewhere. Older builds with inputstream.mpd works O.K.

The getwidevine.sh script should link to the correct libssd_vw.so

Code:

# Sym link to whatever libssd_wv.so we can find...
for l in /usr/lib/libssd_wv.so  ~/.kodi/addons/inputstream.adaptive/lib/libssd_wv.so ~/.kodi/addons/inputstream.mpd/lib/libssd_wv.so; do
  if [ -f ${l} ]; then
    rm -f ~/.kodi/cdm/libssd_wv.so
    ln -fs ${l} ~/.kodi/cdm/libssd_wv.so
    break
  fi
done

It doesn't neither work (for me and obviously sw4y) with clean install of your build and getwidevine.sh nor LibreELEC (Krypton) v7.90.009 ALPHA with actual inputstream.adaptive 1.04.
So I assume its a problem with this specific video addon for DAZN or something wrong with x64 linux versions of decrypter lib. For some people it seems to work, but I don't know if these people uses Intel machines.
