connections on SONY (sound delay)

by Gettinthebug / February 22, 2014 7:25 PM PST

So i have a Sony TV, Sony Blu ray an X box and just bought a Sony sound bar. I also have a Sky box

The Sky box is HDMI'd into the TV port 1
The Blu ray id HDMI'd into the TV port 2
The X box is connected via the audio/vid in analogue
The TV is connected to the sound bar via optical in - out cable.

It all works brilliantly except for the Blu ray which has a time lag on the sound. The Sound bar has an advanced settings menu item for switching 'on' when this happens but I've tried doing that and it seems to have no effect. I notice there are other audio outs on the tv (for eg a USB audio out). Would using this instead of the optical to connect the sound bar make any difference???

Clarification Request
All makes/models please; switcher as fix
by Pepe7 / February 23, 2014 12:52 AM PST

If you truly want help, you need to also provide all makes/model numbers. Hopefully you are aware by now that these components often differ in their functionality/options/ports/etc.

Before we know that though, this is why I often avoid soundbars and stick with a traditional AV receiver. Even a lower end receiver has what we usually need to avoid the nonsense you are experiencing. E.g. ample inputs & audio delay adjustment settings

My 'recipe'. FWIW, Some sort of audio switcher might help/may be required if the soundbar lacks inputs- which they often do.

Skybox (HDMI out) --> (HDMI in HDTV)

HDTV (digital optical out) --> (digital optical in) 3x1 or 2x1 digital optical switcher (can be manual or remote controlled switch)

Xbox (Analog out) --> (analog in) HDTV

Blu Ray player (HDMI out) --> (HDMI in) HDTV
"" "" (digital optical out) --> (digital optical in) digital optical switcher

Digital optical switcher (digital optical out) --> (digital optical in) Sony soundbar

Example of manual & remote controlled switchers. $15 would get your foot in the door Wink

manual switch-

remote version-

*also, you could skip audio to the HDTV altogether, and simply run all three digital optical cables through a switcher, then onward to the soundbar. Ideally the TV is used as a monitor only. No digital outputs on that Xbox? Wink

For now the only way I see passable sync/delay issues is when we connect from source to HT receiver and then to the HDTV.

However many sets will straighten up if you set the audio to stereo PCM. Since the sound bars are not 5.1 you see trouble if you send more than stereo.

Sorry but it's a well discussed area.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
