Brief follow up on the conversation. @Fubie and I video chatted last night and looked into the problem. Turns out GROUPED Sonos speakers throw out errors in the capability.music player setlevel() command. By ungrouping the speakers, we found everything worked as intended.
The other thing we noticed while debugging was that Alexa’s reserved words, although necessary, can be annoying. Does anyone know if there’s a published list of all the reserved words? If so, linking it here would be helpful.
