My new arc ultra has anvannoying problem that did not occur on the sonos amp it replaced: whenever the tv switches audio format (say, from dd 2.0 to dd 5.1) the soundbar goes silent. Occurs 80% of the times more frequent on apple tv) and makes the whole experience a nightmare.

 

My tv is correctly set up to passthrough audio. Only workaround seems to force audio to pcm, which is of course not a solution. My tv is a sony bravia a8g, an older (but great) model with no earc.

Is there any hope? Went through troubleshooting with customer service  but no luck so far.

The best that will give is simple dd5.1. Why would you want that?

I should have some time over the Xmas period to try to speak to a L2 support and see if we can collectively get the to pay proper attention to the problem 

Thanks for your feedback and efforts to date to push the issue with Sonos. As I’ve said before all I did was unplug an ARC and plug in an ARC ULTRA and that’s when the problems started. Sonos need to accept there is a problem with the ARC Ultra

I'm aware of that :-)

It's mostly an interim solution to get something better than pcm stereo without having usability issues. Of couse a fix would be better!
