Sonos version 10.6.2 is available today with some new settings to improve performance while playing audio from Sonos input connections. There are two new settings, Group Audio Delay and Audio Delay

 

The Group Audio Delay will add a delay between incoming TV audio and Sonos. This will reduce the chance of audio issues occuring when your Sonos products are playing the TV audio as part of a group. 

 

The Audio Delay setting determines the speed it takes to start playing a Line-In connection on Sonos. This is the delay on your line-in source. It has a minimum setting of 75 ms, which is the same as the previous delay that we had with the Uncompressed line-in setting. Increasing the delay adds an extra buffer to playback and gives an allowance and tolerance. This will reduce the chance for audio issues occurring when your Sonos products are grouped and playing line-in audio.

 

These options range from low latency which is synced closely to the source and is good for video when you can see it, but it comes with a higher risk of audio dropouts when playing to a group. Alternatively, high latency is not good for audio and video sync, but dramatically reduces the risk of audio dropouts when playing to a group of speakers.

Thank you hopefully this will remove my occasional dropout when listening to line-in sources.

See you can make useful changes.

Sonos version 10.6.2 is available today with some new settings to improve performance while playing audio from Sonos input connections. There are two new settings, Group Audio Delay and Audio Delay.

 

I have two gen 2 Play 5’s connected by line-in to my tv as my prime TV audio source. The in-line setting is currently set to Uncompressed and I don’t have any lip synch problems. I control them from my windows 10 pc and Android 6.0.1 phone (can’t upgrade further). Will any further delays be introduced if I upgrade my Sonos to 10.6.2 and if so will my controllers have the settings available to adjust them? eg compressed/uncompressed, Group Audio Delay and Audio Delay.

Is this update only available for the iPhone and Android devices? I noticed that the SONOS app on my Windows computer is still at 10.6.1 and when checking for updates it indicates that none are available.

This update adds the ability to increase the delay as needed to help add an extra buffer, it’s all optional and isn’t adding an extra delay to the lowest latency that wasn’t there before. Nothing will change regarding your delay on the Play:5s if you update to this build, but you’ll have some options now if you need them.

That’s correct, players stay on the 10.6.1 version number.

What is considered ‘line in’ for this feature?  Are the optical/hdmi-arc connections considered line-in?  Are the RCA inputs considered lined in?  For the Sonos Amp, which has both input types, can you set each on separately?  Maybe more appropriately, are these settings at the system level or the room level?

You’re correct on both of those, melvimbe. 

The TV input is anything coming through optical or HDMI and the line-in connection is anything on the analog RCA. 

These settings are found under the connection they affect. So you’ll find Group Audio Delay under the TV settings and Audio Delay is under Line-in settings.

For the Amp, which has both, each setting operates only for the connection it’s specific to.

Ok, a follow up  question then.  On the ‘group audio delay’, does this mean that it’s now possible to play TV audio in sync across a group?  For example, a TV is connected to a playbar  which is group with a Sonos One.  In normal, no group audio delay, the playbar will play in sync with the TV video and the Sonos One would be slightly behind.  Turning on group audio delay,  will the playbar be out of sync with the TV video, but the playbar + sonos one group play in sync?

No, it doesn’t help with the sync. Using the Grouped Audio Delay will add a delay to the audio of grouped speakers. This adds the option to increase the delay for speakers grouped with the TV speaker. Adding the delay creates an increased buffer and will help prevent cutouts with the higher quality audio streams that comes from TV audio sources. 

@Ryan S : From how the menu system for this delay selection is organised, it would seem that each zone in the system can have a different delay selected - unlike the selection for compressed/uncompressed/automatic which is applied at a system level. Correct?

That’s correct. It’s per device.

Excellent, my always single zone 1 pair was seeing stuttering from the wireless source - Line in jacks on a Connect in the same room. Changing the delay to max for that Connect seems to have fixed that.

And since the system level setting remains uncompressed, the other ethernet wired zones that have a TV fed Connect will still have lip sync between the TV and Sonos sound in any or all of those zones in a group.

Is there any way to set group audio delay to 0 ms? I play the drums and found a way to use the beam as my speaker, but the 75 ms delay is very annoying. How can I bypass this delay?

Is there any way to disable the timeout on line-in? When used as a PC speaker I often miss audio when someone talks in a meeting after a period of silence sufficient to cause the Play:5 to sleep.

I *think* if you turn off auto play, it disables the timeout...but I’m not 100% sure, and have never tried to test.

Hi. Where it says above - “Sonos version 10.6.2 is available today with some new settings to improve performance while playing audio from Sonos input connections. There are two new settings, Group Audio Delay and Audio “ - are these settings supposed to be still around in 12.0.2 - desperately trying to find cause/solution to a 2.3 second delay for line-in on a Play 5 that has appeared a few weeks ago.  I cannot see where these delay settings might be. Thanks, Tim.

Hi,

I would like to cancel this audio delay because I am using one play:5 as speaker for a synthesizer. Therefore I need to hear the sound as soon as I hit a key. Even the 75ms delay is perceptible and really annoying :(

Is there a solution for this ?

Fabrice.

You need to use a digital connection to get rid of the 75ms delay. If the synth has s/pdif output, connect that to a TV-capable Sonos device.

What is going wrong here?

I just turned on group audio delay for the TV input, and it’s putting in the delay to all Sonos speakers BUT the playbar.

Great feature to address dropouts with the tv input, especially now Apple TV can correct for delayed audio. But at the moment it means muting the playbar! Am I doing something wrong?

It would be a great option to have NO delay or zero ms. There are devices/speakers that are within a metre or two that do not need any delay. The delay is not required in may marine setups where two sets of speakers are in different zones and the zones are close.

I have tried grouping the Beam with two Sonos One SLs instead of the surround option as my setup has two Ones as front speakers and Beam as rear (you can take a look at my diagram to explain setup here: https://en.community.sonos.com/advanced-setups-229000/using-sonos-ones-sl-as-front-speakers-and-beam-behind-6851775?postid=16493666#post16493666). Whenever I’m watching TV or a movie, the two front Ones have frequent drop-outs in audio and aren’t in sync causing a reverb effect if I group them. I don’t understand how this is an issue when using Spotify from the app, the sound is distributed equally amongst all speakers without any delays in the room. I have to keep them set as surround instead of grouping but Sonos doesn’t allow you to use the front two One speakers as front and Beam as rear so it’s inverted surround in my setup. Surely this can be fixed with software.

Surely this can be fixed with software.

The audio path from TV to the Beam has to have zero delay, else lip sync problems occur. The audio path to the surrounds also needs to have zero delay, which is why it uses a direct private 5GHz connection.

However, if you just Group speakers together (which is the Sonos raison d'etre), then the live audio from the TV goes over WiFi to up to 31 other devices, and that introduces a delay which is notable if you can hear both the Beam and the grouped speakers. (This is the reverb you can hear).

If using a music source to the Beam (eg Spotify) then the system introduces delay deliberately at the source, so that all grouped items remain in-sync (including the Beam). You can’t tell there is a delay as there is no associated video.

So the design of the Sonos ecosystem and speakers is flawed by WIFI? 😕 Why was this feature implemented if the audio drops out on the Ones in the first place through grouping? I also don’t notice much lip sync issues at 75ms when looking at the projector screen but the audio drop outs are constant when the Beam and Ones are grouped. I set it to surround instead but then the Ones aren’t being used much in my setup.

Sonos’ first products focussed on multi-room synchronised audio - the ability to dynamically group speakers into different combinations of synchronised play. I the system creates a slight buffer before sending out the sound. That way (as I understand it), with clever re-syncing that is rarely or barely detectable, the synchronised multi-room audio is achieved. 

They added Home Theatre capability whilst trying to keep the multi-room capability. For the audio to lag behind the tv signal when you are watching the screen, this lag would not be acceptable. So, to do this the buffer signal delay was still needed before sending the data to the other rooms. If the speakers are in different rooms, so you can hear, for example, a sports commentary whilst grabbing a drink from the kitchen, it doesn’t matter that it’s slightly out of sync. If the speakers are in the same room you’ll hear it like an echo, as you are experiencing.  
Basically, you’re trying to use the speakers in a way they weren’t designed to work.

For what you want, a wired system where you can run whatever output to whatever speaker in whatever location you want seems to be the solution you need.
