Volume button not working when connected to Chromecast

Feature description:

When my Android Pixel 7a screen is locked and I’m casting to Chromecast, I can’t increase/decrease the volume until I unlock the screen. This behaviour doesn’t occur when connected to a BT speaker.

Please enable the physical volume button to increase/decrease when screen is locked for Chromecast casting.

You either have disabled Media Session usage in the app or are using a beta QPR build that have this not working.

Edit and just tested QPR2 beta 1 and they fixed this.
