Hi there!
Using the free Roku mobile app, you can use the Private Listening feature to route your Roku device's audio to your phone. If you then pair your phone to an audio output device via bluetooth, this should achieve the result you are looking for. Hope that helps!
I'll pass along your request for Airplay support to our team.
Thanks,
Tanner
Well I just tried this and the HomePod mini doesn’t show in Bluetooth devices... I’d like to see this feature as well. I’ll be getting another mini and they can be linked for stereo sound and I’d like to be able to airplay sound externally from my Roku TV to them 👍🏼
