Still have the same issue, it still reports that it is using the ALSA sink (even though I really set it to the kodi backend). Tried disabling, uninstall/reinstall ande ven removed the data from librespot in the addon data folder...
Am at a loss why it doesn't function.
(I censored my spotify username on purpose in the code below)
