I am trawling through that massive thread at the moment.
Meanwhile I found this, which might mean I have to connect my external DAC in order for squeezelite to start.
Code
KodiPi:~ # /storage/.kodi/addons/virtual.multimedia-tools/bin/squeezelite -d all=debug

So I connected the DAC and this is what I got
Code
KodiPi:~ # /storage/.kodi/addons/virtual.multimedia-tools/bin/squeezelite -d all=debug -l
