HD Broadcast Audio cuts in and out...

[dhead1]

I was wondering in any one knew anything that might cause my HD Broadcast Audio cuts in and out when going thru my HT system? I have standard tier cable (time warner) and have no cable box or card, just coaxal directly from the wall to the HDTV. I have a toshiba 56" HDTV and I am running optical out to my B&K Ref 50. I have tried different optical cords and determined that it is not the cord, also have determined that it is not the particular input on the ref 50, by trying the cd and dvd input which work fine with their players. When the audio cuts in and out (not constantly but just now and then) the HDTV's audio does not. ( if the tv's volume is up) What I was wondering was if it is the processer or the HDTV? Or maybe just a problem from the broadcast with compression or just processer speed? Any help would be great.

If you have no cable box or cable card and the standard tier from Time Warner then you will not have digital audio and definitely not HD audio/video so the digital out from the TV would not be used. You must also have analog connections from the TV to the receiver otherwise you shouldn't get any sound at all.

The popping noise could be the processor trying to identify the signal and failing because it is not actually getting a digital signal.

MDS,
I dont know, the audio broadcasted is sounding very much the same quality as my DVD 5.1 audio. There isnt and popping sound just the audio cuting out frome time to time for 1-2 seconds.

... also have determined that it is not the particular input on the ref 50, by trying the cd and dvd input which work fine with their players.

If your DVD player, outputting the same type of data (e.g. Dolby Digital) works fine, then it's probably a problem with the TV. You could try borrowing a friend's receiver to see if it still happens if that makes you more confident.

Time Warner cable in Upstate NY does that to me on many channels. It has done it with two different Scientific Atlanta boxes and a Pace box.

Everyone seems to complain about it. Apparently they attribute it to the feed.

Thank you everyone. I appreciate the help.
