Hi Arjan,
There are a few additions to the above:
#1 what I mentioned would be a work-around for a (set of) plugin(s) from contributors (me in this case), I’m not part of the Volumio (core) team and in no position to issue warnings.
#2 most of the time I spend on plugins is supporting them, it’s hard to determine where to do all of the write-ups, because certain threads will be forgotten at some point. So I will do the write-up (once research is done, see #3) on the GitHub page of the plugin: https://github.com/Saiyato/volumio-kodi-plugin
#3 this is a fresh update, I just imaged the latest version for my test Pi and I see the following entries (even though I have a DAC):
PI: HDMI
PI: Analogue
PI: HDMI and Analogue
ALSA: Playback/recording through the PulseAudio sound ser…
ALSA: PulseAudio Sound Server
Which means I’m missing my DAC, same behaviour as you have, this also means it needs more research. Somewhere along the way, something broke down and needs to be fixed.
