Starting yesterday when I change channels on the HD FIOS box- the channels change immediately as usual but the last sentence of the channel audio previous channel loops and repeats for about 7-8 seconds. Once it stops, the audio on the new channel is out of sync. If I change channels again- it corrects iteself. I can usually change about 3-4 more channels and evertything is normal, however it will start up again. This is not a picture problem- just audio as descrived above.
I have unplugged the HDMI- the cable from the wall to the unit- and uplugged the power to the HD unit yesterday (did not matter) and today (Did not matter). Could the HD box need to be replaced? I have an HD DVR downstairs and there is no problem on that system down stairs.
I troubleshooted my problem extensively...and in my case it was the TV. A brand new Vizio LED 40" M series that was causing the problem. Vizios and FIOS audio via HDMI seem to have problems in my opinion.
Not sure if this will help, but did you try going into the DVR customer support menus and selecting the item called Fix Common STB/DVR issues? This can correct a lot of audio & video issues on a DVR. You will have to hunt for this menu item since Verizon for some reason keeps moving it around and renaming it every few months. It will take 5 - 10 minutes to run and will reboot your DVR (perhaps a couple of times).
I don't recommend pulling the plug on a Verizon DVR since you will likely cause more damage to the DVR hard drive. The Verizon DVR is always recording your current channel even when it is in screensaver mode. When you pull the plug, it may cause the recording head on the hard drive to become damaged or damage the recording surface since the drive head is not properly parked when it loses power. At best you will corrupt the filesystem on the hard drive. Try the Fix Common DVR Issues app a couple of times before pulling the plug. Pulling the plug should be the absolute last resort.
Thanks. I wish these posts would have come earlier particulary the "how to" to get into the hidden menu., I tried it with some instructions online, but it must have been older since I could not get into the specific menu on the Verizon box to fix the audio. I called Verizon and they did not know about any hidden menu to access the audio change on the box. I enbded up taking the Vizio back and getting a Samsung. No problems with the Samsung,.
