sync problem using port (or connect)

i tried that it doesnt , it helps some ,but there is still a delay where its not listenable .

if this is an issue with the receiver are some receivers better than others ?

I’m surprise the pure direct causes an issue.   Are you inputting via digital or analog into the receiver.   Maybe it has something to do with the DAC in the receiver if your running digital ….. if so try analog red/white cables to the receiver and see if it makes a difference.  Actually I think the Pure Direct is geared toward the analog inputs so maybe it is your doing digital.

--- ah I see from original post you are doing digital cable - that could be causing the issue … try it with analog cable where the DAC in the Sonos is used instead (which is very good).

There is an Enhancer button on front - for the DAC that should be turned off - that adds processing of the input from the digital input.

adaptive drc should be turned off

this amp has so many processing features no wonder you have issues.

From Yamaha it sounds like you definately want to use analog inputs and Pure Direct

“The Pure Direct mode on my Yamaha AVR is intended for 2 channel analog connected source components - such as a TT or the RCA outputs from a CDP or SACD player.

Pure Direct maintains an analog path from the outputs of the source component all the way thru the AVR with NO A/D, NO DSP/AutoEQ, and no backend D/A to the output stages and to your speakers.”

Sounds like exactly what you are wanting.
