Or even if it was just always left to output stereo because it is easy enough to turn down the volume at the TV. Then the output could be fed anywhere on the same basis. eg TV's in several rooms. This is something I imagine a goodly number of people want to do.
You can do that - most sources allow the selection of the audio format output. Fix the audio to 2-channel PCM "stereo" and everything will get that.
I don't want my amp making every decision on my behalf.
It's a reasonable process given that the choice otherwise would be silence or static...
Actually I would have preferred HDMI to leave off all this auto selecting and leave it up to the receiving device to decide how to handle it. Most TVs probably don't support surround sound formats BUT surely the receiving HDMI interface in the TV could have been designed to decide how to handle the audio. Its a few integated circuits and you can build whatever you like into them. BUT I suspect RIAA etc had a lot to do with deciding what goes into HDMI so we come back to conspiracy theories. It might well be that whatever they decided to fix or control has nothing to do with this issue but this is a consequence of that decision. If so it demonstrates The Law of Second Consequences.
No, it's licensing for the surround decoders and the chips to do the work, which adds dollars to the cost of the TV. Since the surround format doesn't do "any good" for the TV, the makers logically didn't raise their costs for no gain...
And the RIAA has nothing to do with HDMI. MPAA is the evil force behind HDCP (which is applied over HDMI), but none of this has anything to do with audio formats. HDMI came from DVI, the computer-to-monitor digital interface that didn't have any audio support. So they added it, and the format negotiation just like they did for video resolution / capabilities. But it didn't account for "distributed" video systems where multiple displays were connected to a single device. Simply wasn't something they dealt with...
Now, some newer models are including the decoders to deal with this - I suspect Dolby/DTS may have come up with a limited licensing scheme for 2-channel devices because of this issue - lowering the cost of implementation while expanding their own market...
Okay what I need is a splitter that sequences turning on the output channlels. Channel 1 on first then 30 seconds later channel 2 and maybe all the channels. Then my output source will set itself up correctly for my amp then afterwards who cares. As long as HDMI doesn't recheck during playback. I tested this by leaving the kitchen TV off until everything was working in the lounge and then turning the kitchen TV on. This will work for me okay - not sure if my wife will remember to sequence things correctly though. HDMI is trying to be too "cute" for my liking.
I think that this is only required when I am playing back a DVD rip. TV series seem okay since it is probably the lowest common denominator.
The sequencing and compatibility checks may occur when you load media, change channels, input or some other event, so you'll have to trial and error to see what the behavior of your devices looks like.
