Can the sound be balanced between portals with Gateway so you don't have one sound delayed to the other?
The sound system you're connected might be causing the syncing issues. We have a thread on Audio Video Synch issues with the Gateway. Try using some of the techniques suggested here Re: Audio Video Synchronization to resolve it.
So you have two Portals that you can hear from a location, when they are on the same channel, there is a noticeable delay in the audio from one to the other.
My first thought is the sound equipment, one TV taking longer to process the signal than the other for example
Yes. I have one unit on a seperate sound system in the LR and another using the TV sound in the kitchen but the sound and picture are delayed and overlap. This is a problem when you move from one room to the other watching, say, the CHEK news, and you want to watch the same show on both. I have a third portal inthe BR and if I turn it up the three are out of sync.
