I’m tryIng to use the Onkyo / Sonos connection to send sound from a TV to another room. The Onkyo and Sonos networks are connected via WiFi, hard wiring is not an option. While I can configure the system to play back the TV output sound from the Onkyo to Sonos Connect 2 and then to Sonos Play 1 speakers, there is one problem. There’s a transmission delay built in, causing the sound in room 2 to be about 0,7 seconds behind the source room. It sounds like a stadium PA to put it charitably. I have been told this is a digital delay (buffering) built into the system. Understandable, but drives me mad. This transmission delay only exists with sound from the TV (Sony 4K using HDMI Arc connnection to the Onkyo receiver). CDs, DVDs and LPs(!) all work fine. Ditto streaming & internet radio services.
On a previous (Onkyo) receiver I used the Tape In / Tape Out analog ports and had no difficulties with this. Anybody have a nice hack? The next step is to run cable and hardwire a different pair of speakers to the receiver and bypass Sonos. I can provide more info if needed.
Thanks in advance!
