Need possibility of adding delay in addition to the normal 70ms

You could also split the audio from the chromecast with it going direct to TV and then the other going to the connect input.

Why?

The TV would play the direct feed from the Chromecast dongle then (and add delay as the TV is obviously doing).

But - feeding into the input on the Connect will also delay the signal about 70ms in the case of Sonos digitizing and setting up to stream in sync.

So then any speaker playing Chromecast in Sonos will be delayed 70ms from the chromecast feed. Question is - will that then make it more in sync with the TV delayed sound (TV may be delaying more than 70ms but you'll see if test).

Then possibility chromecast to TV and Sonos will make the 2 systems more in-sync.

Thanks again Chris, I wanted to wait with my reply until I had the Chromecast audio set up. I now have it. It took a little effort, because I could never get that temporary wifi network that is mentioned in the instructions, but I set it up with my regular wifi and it works. This morning I had micro cuts in the music, but that seems to have disappeared for the time being. One aspect that is complicated is the volume setting, in 3 places: the Sonos application, the iPhone, and the Chromecast application.

Your last suggestion is very imaginative indeed. It would require more cables to split the signal. I'll leave it for later.

Anyway, what was originally a post out of frustration more than anything else has provided me with very useful advice. Thank you.

Keep that chromecast dongle as far away from any other wifi equipment as you can (don't have it just sitting right on top of the connect).

I would keep the Chromecast volume at a fixed level (like 90%) then adjust just the Sonos volume as you would normally.

The ability for a delay would seem to be a good suggestion to solve the problem, but I have no idea if it is technically feasible.

Personally, if listening to music I don't have the AV amp doing any processing - it is all designed for stereo, so why would you need to have a stereo audio track in surround? It might be fun, but it isn't true music reproduction.
Also, I think it is unfair of some of the comments in this thread to point the finger of blame at Sonos and argue with their "perfect sync" statement. The Sonos equipment is in perfect sync.

There are different ways and reasons to consume music. There's "listening to music," where I sit down in front of high quality speakers, put on a great album, and just listen. And then there's "enjoying music," where I put something on in the background while I work, or hang out with friends, or make dinner. Perfect fidelity isn't always the most important goal.

I have Sonos in a room with 5 in-ceiling speakers. People are typically listening from many points in the room, and the adjacent room. To get the true and proper stereo sound, you'd need to be reasonably close to centered between the left and right channels, but that's just not the reality of the way the room is used (and in-ceiling speakers aren't very good for that anyway). Letting the AVR do its "5 channel stereo" thing makes the music more even throughout the room, and is generally more pleasant to listen to in a casual setting. The room correction (Audyssey) also helps it sound better with the small and imperfectly placed speakers.

I have a nice system in another room that I can use if I want to listen to the highest-quality sound (though in that case I don't typically use Sonos as the source). But when it's a bunch of people over for dinner, the benefits of having all of the speakers playing music far outweighs the loss of fidelity.

Hello, Thank you all for the comments. This request has been passed on to our Product Development team for review.

This was 3 years ago and they have yet to solve this issue. I called Sonos yesterday and the reps suggestion was I run a separate amp off my receiver and remove the sonos amp that runs the other room.
THis defeats the entire purpose of sonos!

Sonos created a delay in the video/audio side for their playbar so they have the technology, just need to implement into the connect amp settings.

As a new Sonos owner it is unsettling that Sonos has not even answered the community directly here. This is clearly a troubling problem for their users. I suspect it is not something they can do easily and/or something they feel does not have a good return on their investment. It would be nice to get an official update.

Hi Bob_m10, thanks for reaching out. We'll make sure this is still on the request sheet and will add your interest to it. There isn't really any update to share on if or when as we don't talk about future development generally.

In some situations, using different inputs or toggling off DSP on the receiver will help with any delay happening between the two devices. Generally speaking, what happens is that the Sonos software has been designed specifically to keep all Sonos players in sync automatically, so your CONNECT and the CONNECT:AMP or other players are all playing at the same timing. The receiver is adding a processing delay once the audio gets to it from the CONNECT.

So the suggestion here that we passed on is to have an option to add a delay to other players grouped to the CONNECT, or to add a pre-buffer to the CONNECT, so that it was timed faster than other players when grouped. Again, no particulars to share on that request however.

Thanks again!

Appreciate the update Ryan. -Bob

Just hooked up a couple of Connect AMP's and a Connect to my Sony ZA5000-ES ($3500) AVR. Very disappointing to hear this delay even when running audio direct. I'm using $1K each main speakers in the family room and $1K/pr speakers on the patio because I wanted to have fantastic sound for this event. Sounds like I'm in the hallway of a stadium 😞 Any updates on this 4 year old feature request or ideas yet before I return everything? Thx
