I don't think that the sync problem will ever be fixed unless there is a new X1 box. The level 2 tech (seems to know what he is doing and has been helpful with timely followups) I've been dealing with told me last night that his engineers (who have been incredulously working on this problem for 7-8 months) said that the sync issue is related to the box not having backward capability to work with older AVRs that don't have hdmi. He also related a lot of gibberish about how the sound hookups should be wired; none of which made sense to me. Like, for example, the coax out from the box is meant to go to the TV and not the AVR??? I'm going to swap boxes and put the DVR into the room with the surround sound setup, and the terminal box into the room with sound only from the TV. As those hookup to the DVR don't seem to have a problem, we'll see what happens when I swap...
Surround sound system in the livingroom, coax from terminal box to older AVR (no hdmi), component from box to TV. Hub in the bedroom, no SS, hdmi from box to TV.
Livingroom system plays 5.1DD, but ALL DVR'd material sound is out of sync. Comcast level 2 tech says terminal box must be hooked to AVR via hdmi to get SS and voice sync for DRV'd material. Furthermore, they've been working on this problem for about 8 months and see no solution to this issue. Only way out is to get another DVR (at $17/mo) or to try to swap boxes between rooms. Wife let me try the swap because she just about always watches DVR'd material AND when terminal box is hooked via hdmi to the TV, DRV'd material is in sound sync.
The two boxes have different inputs/outputs. Whereas the terminal box had hdmi, component and coax outputs, the hub box doesn't; it only has hdmi and digital optical outputs. Had some concern about using hdmi from DVR to TV as when I did this with the terminal box, couldn't get 5.1DD...had to use component cables to get DD. Nonetheless, in the livingroom, I used optical cable from hub box to AVR and hdmi from box to TV. Everything is now working properly: 5.1 DD and DVR'd material is in sound sync. Of course, no thanks to Comcast...I really hate corporate Comcast, not their reps, because corporate just doesn't tell their reps what really is going on until it is too late.
