Set Media Volume with Siri on Device Class of TV or similar

Hello,

I’ve gotten most of the features that I want out of Homekit with Device Class of “TV” for Receiver and/or Actual TVs. However, one thing I’ve noticed is that I can’t seem to tell Siri to set the volume on these devices. I can adjust the volume via the iOS remote app and selecting the proper entity, but all I get from Siri is “I’m having trouble adjusting the volume” or something like that.

Has anyone been able to get this to work and adjust their volume via HomePod or iPhone “Hey Siri”?

I know in the past, people have just been using Template Light for a hacky workaround, but I figured we might have made some progress on this, especially since Input Selects in Homekit work like a charm.

I have the exact same problem. The remote app works, but Siri gives the same message.
