I understand that using a Port to stream music to non-Sonos speakers though an AV receiver works great. But if you want to group your Port (room) with Sonos speakers in another room (I have Sonos Ones) there is a delay. So it is out of sync. One solution is to use direct mode (or similar modes) on the AV receiver, but that takes away the sub and room equalization, etc.
So is anyone using the Port with an AV receiver, and has been able to use modes other than pure/direct (or whatever the AV receiver calls it) - and still have it sync with grouped Sonos speakers? I would like to use All CH Stereo with my AV receiver (where all speakers play, including the sub). But not sure if that is considered “processing” that will introduce delay. At a minimum, I would like to use Stereo (which uses the sub and equalization).

No-one could really comment without knowing what AV receiver you’re using. Have you consulted the AVR’s user documentation to try and establish the All CH Stereo delay figure?
There is no inbuilt Sonos solution to this issue. The Port’s outputs will be in sync with the other Sonos players; they can’t be moved ahead in time.
