I have tried every setting in the Samsung s95b audio and sonos app and Apple TV and still cannot get the audio to sync! I got the arc from Costco so wondering if it’s a hardware issue or the default/included hdmi cable that’s the issue?

Hi.  Assuming that the audio is lagging the picture, it is the failure of the TV to ensure the audio output to an external speaker synchs with the picture.  If the audio lags there is nothing the external speaker can do to correct it: it cannot play sound before it receives it and it has no control over the video.

The only solution is to bypass the TV with the audio.  There are a few such ‘eARC audio extractors” around now: the HDFury Arcana, one by Feintech and another that I can’t remember the name of.  There are lots of threads on this topic.

There is the HD Fury Arcana, the Feintech VAX04101k, and the latest, and least expensive, I think,  is the OREI HDA-935. Check your local retailers for availability, or Amazon. You can also order from those links from the companies directly, I think.


Thanks for supplying this info Bruce!

@Abergervt Be sure to set the Digital Audio Output setting on the TV to Passthrough, not Auto. If this doesn’t work, you can also try disabling eARC in your TV settings.
