I thought modern av gear had auto delay to sync up source and display. LG c9 with Panasonic 820.

Also have oppo 983 and alfawise box.

Are there any test video with audio to make it easy to set by guestimating it a blinking onscreen symbol with a quick audio click should be suitable.
 
Doesn't always get it right. Flags could be off.

Test disc are your friend: Spears & Munsil, or DVE HD Basics.
 
I've got Avia dvd and spears on Blu-ray, where are they what are the specific tests called?

Alfawise, oppo 983, Panasonic 820, have audio delay options. As does the tv. And the Av pre amp.
 
AV Sync

820 and Oppo both have 7.1 analogue outs which is why they provide output sync. Shouldn't need it going through the amp to the TV.

I have to use AV Sync adjustment on the TV when playing media files from USB through TVs internal speaker.

Optical out from the TV doesn't provide the auto adjustment of AV Sync/Lipsync which would correct the timing for an external sound system. Only HDMI (via ARC) does this because it contains the flagging info. This is why your AV sync (via Opt out to the Lexicon MC-8) isn't adjusting automatically.

The lipsync/AV sync is adjusting, but it's doing so for the TV speakers and not the sound going out to the Lexicon.

Since your final connection to your surround system is via Optical, and that's limited to 5.1 DD/DTS, which itself is lossy and carries no lipsync auto adjust anyway, and you have good/excellent HD audio sources in the Oppo and Panasonic, then in your case with the Lexicon MC-8 you'd be far better off connecting audio to that directly.

The MC-8 has:
4x Optical TOSlink
4x coax SPDIF
2x 5.1 analogue audio in

Connect the Oppo to one of the 5.1 analogue in; you'll get HD audio in Dolby True HD and DTS Master Audio, plus DD/DTS plus unbalanced analogue stereo

Repeat the above for the Pana 820

Use 1x Optical for the Alfawise Android box

Use 1x Optical for the LG C9 TV (HDMI audio from sources, switched and converted to Optical out at 2ch PCM, DD/DTS 5.1 by the TV.)

The above gives you no loss in convenience if you want the option to retain the simplicity of the TV acting as the audio switch via the existing Optical in on the Lexicon.

You won't solve auto lipsync/AV sync adjustment without first changing the pre-amp to one with HDMI inputs and ARC with CEC, so you've lost nothing in that respect. However, if you follow my advice then your system will take a huge leap forward for sound quality from Blu-ray and UHD 4K discs, plus you'll get the ability to dial in individual settings for lipsync for each direct source. That's got to be worth the effort.
 
Sources are near TV so audio is routed through TV. Can't be bothered move bd to mc-8 go get hd audio.

I know optical doesn't sync audio but with sources going straight to TV I thought be ability to check it is syncing I can't see any hdmi options.

I can sync manually as each source plus the TV and the Av pre can adjust delay, but want to check if they are in sync then adjust.

What is the test on avia dvd and spears bd?
 
I've told you already, AV Sync or Lip Sync. Get the bloody discs out and look on the menus. Not hard to do.

This is NOT difficult to find. Far from it. This is more than you deserve. If you can't be arsed to look properly, then I'm not going to enable that laziness. You're a big boy, and quick to show off your toys. Time to put the big boy pants on now, I think

[BTW - I fully expect you to react by replying that you've already found it. That is until you read this line. I doubt you have found it, because you're too used to people wiping your backside.]
 
Since mines the version one, and I'm not going to rebuy it, are there any Avi /mkv files which are available, put onto usb stick and adjust on each source device?

Or if I find it's the same on every source then simply use the Av sync delay on the lexicon.
