Why isn't my Google Assistant integration working correctly (Especially with Sonos)

Hey there, fairly new to Home Assistant.

I am having a lot of issues with my google assistant integration I setup, for some reason, alot of my devices show up as set-top boxes. A perfect example is my Sonos, for some reason all 4 players are only showing up as STB’s, this means that I can only turn them on or off (which you cant even do anyways). Does anyone have an idea on what’s causing it? Thank you!!!
