Maybe you guys can help me out with a better understanding of the various Bravia Sync settings of the TV. We’ve had our 900f for about a year now, but since we got a sound bar, my wife has basically hated the whole setup.
To get to the core of the problem, basically any time you turn on the tv, the CEC will turn on the sound bar immediately, it since the sound bar has to boot quickly, you get a whole handshake of “changing sound to tv speakers,” then a pause and black screen, then “changing sound to audio system” after it sees the sound bar, and another black screen and pause. Then things are usually okay for a while, however with the bugs, which I believe were introduced in the December firmware, it would occasionally just drop the Soundbar signal entirely, switch to the tv speakers, and then if you switched back to the audio system, it would be broken and often require a hard restart of the soundbar.
In addition to all of this, I felt that using ARC audio from hdmi devices such as my DirecTV box was introducing an intolerable amount of audio lag, which left the video ahead of the sound, which is difficult to adjust for. The A/V sync feature on the 900f does a decent enough job, though not perfect, but you can’t use that because it adds a screen flicker if you use it in conjunction with local dimming.
The easiest solution to that was to run an optical cable from my DirecTV box direct to the sound bar, but this left me with two problems. The AV sync was different between DirecTV and my AppleTV, which runs direct through the soundbar and the TVs ARC channel, so it would require audio delay futzing on a regular basis. And also, no matter how many times I would select the optical source on my soundbar, randomly at any time, the TV would just decide to push a CEC command to cause the sound bar to switch back to the ARC audio. Is there any way to reign in the CEC chaos on this thing?
Finally, I decided to get an HDMI switch to just run everything through the soundbar to the TV. On paper, this works great, A.V. Sync is easier to manage, I only have to worry about adjusting my video settings for one input, and the switch should handle input switching by itself. Except now the 900f is haywire. I’ve reset the Bravia sync settings several times now, but somehow whenever I hit the menu button on my Apple TV to activate it, the tv thinks the Apple TV is on HDMI 1, even though there isn’t even a cable plugged into that port. I have fixed this by turning CEC on the Apple TV off, but now this means that I have to manual change the input to Apple TV, as well as not being able to turn the tv off with the Apple TV alone. And to top this all off, I still have to go through the same dance of speaker switching the 900f does whenever turning on the set. Is there any way to just tell it to always stay on Audio System unless I manually switch over to the internal speakers??
