My action streams audio to a Google-Home via MediaResponse webhook call. This works well, but even changing the volume isn't possible while streaming! Tested on simulator and Google-Home mini. Only intents of my action are recognized.
My expectation was, that the Google standard commands (volume up, down, ask the time...) are still working, even if a started action streams the audio. But Google does not understand the command and cancels my action after 4 unrecognized tries.
Is this a normal behavior? Hopefully not, would be a big show stopper...
