I have a quite old HD tv (Pioneer) that I love and still has lots of legs. On Installation of the amp, we tried hooking up the tv to the in wall speakers from SONOS and the AMP as well.
What occurred was about a 2 second latency on the relationship between the visual words spoken and the sound occurring which was quite distracting. The tech moved it to PDM on the settings which had only marginal if any effect.
Is there any way to obtain added hardware to narrow/eliminate this issue? The aesthetic of where the speakers had to be placed really necessitates removing the existing tv speakers (either side of the tv which is wall mounted also) to achieve a more pleasing wall.
