I have three Sonos Playbar speakers in three different rooms, all hard wired (RJ45 Cat6E cables) to my router. There is a very distinct lag between the speakers which is annoying enough that I do not have any more than one on at any time. The reason I installed the Sonos system was to have matching sound throughout the house so I am wondering if there is some way to adjust the sound to match. I control it through my desktop Windows 10 computer, not through a cell phone. Any ideas please?

So to be clear, you are grouping them using the speaker/room grouping screen (or grouping function), ticking the rooms you want to play together, and applying this, but they are still playing out of sync?

If you Group the Rooms in the SONOS controller, they will be time aligned. However, sound is pokey, traveling at about one foot per millisecond. Consider two speakers ‘A’ and ‘B’ separated by 30 feet, wired to the same amplifier, with a listener positioned next to each speaker. Listener ‘A’ will claim that speaker ‘B’ is 30ms late. Likewise, listener ‘B’ will claim that ‘A’ is late, while listener ‘C’ standing at the midpoint will claim that the speakers are time aligned. All three observers are correct.

Well that seems to have done it. I am new to Sonos and did not even know that I could group the rooms and have been playing them separately til now. I did find the icon that allows me to group rooms and set all three rooms as one group and that seems to have solved the issue. Thank you for your help and patience.

Happy to help! Glad that has sorted it. (You can group rooms in any combination, or untick the speakers to go back to playing in one room again.)
