Trying to figure out a small problem with announcements into the kids bedrooms. I have an 8 zone C4/Triad Amp, 8x8 C4 AV matrix and an EA-5. I've never hooked up the ceiling speakers in the kids rooms, but I have some spare zones so I thought that would be a good thing to do - they can have a TIDAL stream each, and in return I can play announcements for dinner time etc.
Their existing C4 setup for their bedrooms simply consists of a Roku TV and some lighting. The video end point is The Roku TV, and Audio End Point 1 is the TV. Video Volume 1/Audio Volume 1 is obviously also the Roku TV. I added a zone of the Amp to be Audio End Point 2, and Audio Volume 2 is the corresponding zone of the AV matrix. This works fine for playing TIDAL, and controlling volume works as expected.
However - when I add the room in Announcement Agent, I get a problem with setting the volume, due to a lack of 'discrete volume control'. It works in the master bedroom, but this only has one Video/Audio end point. What am I doing wrong ? As you can see, the volume settings are greyed out on the two kids rooms.
Assuming that I can fix this, what's the best text-to-speech driver for announcements ? Something that my wife can use from a touch screen/app. And/or can they be triggered by an Alexa command in the kitchen if they are pre-programmed ?
