The problem is that according to your logs the rr-config-tool wasn't started or did not run properly so it won't create the settings.xml and so later no proper asound.conf will be created.
settings.xml is created if I change something else in the plugin, such as the kms setting. the problem is not the settings.xml cannot be created, it is that whatever runs to create asound.conf on boot or from the plugin when you select a device from the addon does not seem to run.
