I still hold to my original advice, 919 + soundbridge or 919+squeezebox. Stop second guessing me! If I thought there was a better solution for you I would have mentioned it already.
- It is completely bizarre to want to run only TV speakers. You'll get much, much better sound on your TV shows + movies + music inside if you get external speakers. Run only the front 3 + sub if you don't want to run surround. Or at least front 2 + sub. Or a soundbar + sub. You are kind of wasting having a receiver.
- even if you do only run TV speakers, you still need 2nd zone capability if you are using the receiver for switching. This is because whatever is selected on the receiver is going to be fed to the TV and the outside zone, while you said you wanted independent audio. If you want to use your current receiver (not get a new one at all; if you are getting a new one might as well get zone 2 capability, not the Sony), you'll have to make two separate connections for all devices that you want to play on both the TV & the outside zone. You'd connect the source directly to the TV, bypassing the receiver, for use with the TV speakers, and separate connection to the receiver which would only send audio outside.
- Bravia sync is not very useful IMO. It does things like automatically turn on receiver + TV when you put a disc in the DVD player, if they are new enough to all have HDMI-CEC and don't have incompatibilities with each other. But IMO a universal remote like a Harmony accomplishes the same thing, in a much more comprehensive manner, that doesn't depend on equipment compatibility. Since I view a universal remote as a necessity, that obviates any benefit of Bravia sync.
-dmport. Yes, it can stream audio from PC, but only after addition of an expensive adapter such as the Sony TDM-NC1. This is almost as expensive as a soundbridge, doesn't have the features/format compatibility, plus it traps you into only Sony receivers, while a soundbridge is universally compatible. Compare the ratings of this on Amazon for this vs. the Roku soundbridge 1000, 1.25 vs. 4 stars.
