I have a very slight audio lag with my sound bar, but it is really driving me crazy.
I have had the Vizio M55-D0 for about 6 months, never thought about sound synch issues when I first got it; sound from he TV was lackluster, but okay. I got the Sonos Playbar last month. Something seemed a little off with the sound, but I would have been hard pressed to tell you which way at first. After a week I decided something was certainly off. Found the sound delay option on Sonos, but that made the problem worse. Turns out the sound is slightly behind the picture through the Playbar. Double checked the Sonos Playbar setting and the TV setting to turn sound lag down to zero.
When I turn the TV speakers on, there is definitely a noticeable echo between the Playbar and TV. Playing around, I switched the optical cable from (i) outputting from my TV to the Playbar to (ii) outputting from my 4k Receiver to the Playbar, and the audio lag seems to almost entirely drop away. Echo between the TV speakers and the Sonos also become pretty negligible. The problem is obviously if I switch to other sources, then I need to move the optical cable.
This might be just a little annoying in the future, but I am worried that it will lead to other problems in the future and I'll be stuck with a system that just isn't up to my needs.
Anyone have any other suggestions? I don't see a sound lag/video lag setting on my receiver, and am not sure the problem is really there anyway. TV seems like it might be the main culprit, but I am stuck with it for the foreseeable future. Anything else I should be trying here?
From one other post, I saw someone was happy when they removed the ethernet cord from the Playbar. I tried that and didn't see much improvement. Willing to try any other ideas people have, or if they know of a way to slow the video or speed the audio from any of the 4k receiver, Vizio or Sonos menus (last one is unlikely, I know), I'm all ears.
I have 8 other Sonos speakers around the house and really want this to work out, but am pretty uneasy about keeping the Playbar for a less than perfect setup going forward, and am coming up on the return by date pretty quickly.
