I've been trying to use the Google home App to cast my screen to a TV or my Audio to the googles around my house but when I try casting via the Google home app it says its casting but no audio or visual actually gets cast and the cast quits after a few seconds.
I have only been able to get it working if the casting is built into the app itself, such as YT music, YouTube, or Pulsar.
I've even tried using the compatibility mode but it doesn't work. This is on a Pixel 9a(stable release 2026021200) and maybe others have better success.
