Better HDMI + HomePod compatibility

I really want to use my HomePod alongside Infuse and my BenQ projector but at this time, I can’t really use the HomePod ans Infuse via HDMI at the same Time, it’s really (really) buggy !
A Better implementation of this feature would be realy appreciated.

PS: Apologies for my english… I’m French !

It may help if you’d clarify what you mean by buggy.
