Sonos Port Audio Delay

Is there a fix for the Sonos Port audio delay? It seems that 10.5 fixed the (really bad) delay when using the line in, however, this is still a slight echo delay when using it with my receiver with any source (such as Spotify). This occurs both with digital coax and analog RCA. It’s worth noting I don’t have this delay when using AirPlay 2 with my AppleTV (via HDMI) and the other Sonos speakers using AirPlay 2.

The delay is in your receiver. Demonstrably there can be no ‘fix’ in the Port, as that would imply a negative delay. Sometimes a ‘direct’ setting in the receiver can be the solution, disabling all sound processing. 

 

A negative delay would be a solution, I believe this is what Google does. Demonstrably it’s an addressable problem though, as my AppleTV, which is connected via HDMI, is perfectly in sync, and HDMI is a longer, slower signal chain, and that’s with room correction and surround matrixing.

How does one create a negative delay?  How can the Port play the data before it is received? How does Google do this?

I can understand the Apple working to keep the audio and video in sync fairly easily, you just delay one or the other until they play at the same time, I just can’t make a negative delay in the Port work in my mind.

Having the same issue. Is there a way to adjust the delay to certain speakers/groups?

A negative delay could be achieved by adding delay to all the other outputs.

@ShaddyZ Agree. Is there a way to do this with Sonos?
