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

unacceptable that this issue is still not resolved. i have stopped recommending sonos components to friends as this issue is a major flaw in the products. shame on you sonos!

Don't let the boilerplate "this has been forwarded to development teams" get your hopes up. Look at the discussion forums. This was reported years ago but hasn't changed so it is either something they consider a non-priority or is something they can't change due to hardware limitations.
This used to be a feature on older hw/sw, It was removed at some point because they resolved the sync issues...enter the modern AV system....we need it back SONOS!

I too have stopped using Sonos in my smart home deployments due to this issue...You can't put hardware with this issue in multi-million dollar homes and expect to stay in business (or get paid). I now use Elan and am tickled pink. Much more spendy, but way more powerful. And their developers actually respond to customer issues.

Another request for the manual synchronisation feature here! I've just bought a Connect for the living room and used our existing sound system there and now there's a horrible delay! The fact that the living room system is the loudest in the house means you can hear the delay in all the other rooms! This is a critical feature and quite honestly I'm surprised the Connect passed quality assurance testing as it is. It's not fit for purpose which is a real shame as the rest of the system is just SO good.

If anyone is looking for an AV receiver for use with Sonos, I just bought a Sony STRDH820 and was delighted to find there is no noticeable timing lag. Previously I tried a Yamaha xxx-371 and there was always an echo from the TV room, no matter what setting I tried. The Yamaha went back to the shop and I kept looking. None of the AVR manufacturers specify lag so it is impossible to know until one gets the AVR home (unless the shop is willing to demo with a Sonos system). For anyone interested, I am using an analogue input from a ZP-80, with all digital processing on the AVR switched off on that input channel. This normally means no subwoofer output, but luckily there is a "Multi-Stereo" setting that seems to work fine and sends a signal to the sub. Happy Days! Ok the sound is not quite as good as my outgoing stereo amp, but I couldn't use that to connect all my other gear together. My tip to anyone purchasing an AVR for use with Sonos is to make sure the store has a no-quibble refund policy since excessive lag won't necessarily be recognised as a reason to return.

Any update Sonos? Please. I have not been able to play music as a whole system for.. damn ..years now! This is all I want for Christmas.

+1, please!

birthday party at the house...need this to buy more speakers! sonos?!? pretty please?!? let me buy MORE of YOUR stuff! thx.

Hello all,

A few days ago, after ample consideration, I bought a Sonos Connect (to link my receiver) and 2 Play:5 units (for kitchen and study, both without doors adjacent to the living), after being assured by the salesman that Sonos could be integrated flawlessly with my current equipment.

After some testing (and some reading on the forum, to make sure it wasn't my fault) i found this is not always true. (By the way: for the test all units were grouped in one zone).

1. Sound source: Sonos. Receiver in direct mode. Result: Audio is in sync.
2. Sound source: Sonos. Receiver in digital mode. Result: Audio of receiver is delayed (due to the digital processing of the receiver). Solution: adjustable delay (of audio out) in Sonos, as proposed in this thread.
3. Sound source: Receiver.  Result: Audio of Sonos is delayed (due to processing within the Sonos system) Solution: cannot be solved by Sonos, but should be addressed by the receiver.

Fortunately, all other functions worked just fine!!
Unfortunely, not solving this issue makes you feel listening to a public address system on an empty railway station, which seriously degrades this beautiful HiFi Sonos system.

I know that this issue has been brought to the attention of product development, but this was 11 month ago. Since than, the issue is marked "under consideration".

Assuming Sonos takes their (mostly enthousiastic) customers seriously, I think it is more than time for a serious update. Will this issue be addressed? Is it possible with the current hardware, or does it needs a hardware change? Etc.etc.

So Sonos, what's keeping you?

(Of course you know that in order to keep your customers happy, you should manage their expectations! Silence isn't going to do that for you....)
