So far I like my Sonos speakers but find it odd that for something so expensive, it doesn’t support what I consider basic functionality. Since Sonos supports TuneIn, it seems to me it should be able to let me login to my TuneIn account so I can play the music I have subscribed to. I don’t want to subscribe to the Sonos radio stream. My workaround is to stream TuneIn to my Google Cast with TV which is connected to my Arc.
Looking through the community archives, it seems there’s a lot of people that want this but Sonos isn’t interested.
