All lights problem with Google Assistant

Got google assistant to work, so I’m able to control my Ikea lights. Me happy.

I’ve got two questions.

For some reason I can’t say turn on all lights, Google Home wil return a message “I’m sorry, there was an error”. Have had this error for ages, was also the case with emulated Hue.

And I’ve got a question, Google assistant is now exposed to lights, groups and switches, But can also be exposed to media players. I’ve got a Sonos connected to Hassio, would that mean I can control it from Google Assistant or am I dreaming here if I expose media players also?
