I have Sonos Port connected via CO-AX to an A/V Receiver. Three other Sonos speakers, at the corners of a large room, are all within listening radius for each other including the receiver listening to the Port’s output. Regardless of Audio Delay settings the Port is always just a few ms lagging behind the other three perfectly synchronized speakers. While enabling the receiver’s PURE DIRECT mode has reduced some lag, it’s still so present where an artificial reverb is created when the Port participates in playback. Is there anything I can do to mitigate this? Is there a chance there’s a way to reach the development team to request injecting a way to set a delay on “the rest of the Sonos installation” to reduce this reverb effect from the Port’s plus receiver’s output lag?
Port Audio Lags Behind All Other Sonos Devices

The Port is connected to a receiver. Any delay could be caused by either device. Sonos is designed to work together with other devices - as proven by the fact that the other speakers do not lag. So I’d look at the receiver. As you’ve found out the direct mode partly solves the problem. Maybe that’s all there is though.

I expect that PURE DIRECT would disable all digital processing (and associated delays). Check to see if there are any other processing modes. Maybe the receiver’s tone control needs to be separately disabled.
