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.
