audio out of sync and now intermittent sound drop

[news]

Months ago, I had an old Telus modem and old PVR. Everything worked fine. Happy camper. Then we experienced some quality problems that were found to be a bad set of wires.

The wires were switched out for another pair, and at the same time we were provided with a new modem and new DVR and new HDMI cables. And that's when the audio-sync issues began. Fixing this problem requires unplugging the TV. Annoying. I find now that I can usually get the audio back in sync with the moving lips on the screen by cycling through the audio sources and back to the sound bar once again. Still annoying but not as bad as having to go over and unplug the TV.

Samsung TV and sound bar. Modem Actiontec T3200M. ARRIS DVR VIP5662W. Telus-branded HDMI cables. The technician said these are all current devices.

I recently decided to upgrade to Internet-75 where a second pair of wires is connected to the modem. Internet speed is nice. WiFi fast. But now the sound on the TV intermittently drops for a few seconds. Randomly, but frequently enough to be most annoying. Back up the DVR a bit and replay and the sound is there. So I think this is something inside the DVR that loses the audio momentarily for some reason. The sound is there, but it doesn't get sent to the TV unless I back it up.

There is no audio sync/drop issue when streaming (WiFi via the modem) from a different device, or DVD player. Just from the DVR.

I think there is a problem with the DVR. Maybe now the signal is coming in so fast it can't handle it properly? Buffer overflow? Can't tell, but I do have an optic cable connection I could plug in and try out to see if it's the HDMI interface.

This type of sound cutting out and/or audio sync problem shows up in a number of other posts, but I have not found a definitive solution in any of them. You'd think someone would have an answer by now?

Is there something inherently wrong with this DVR model?
