Home Theater audio problems

[johnjbruin]

Here is the setup:
TV: Samsung DLP
HD Source: Dish Network DVR Box
Audio: Samsung HT System

Connection: TV is getting signal from the Dish box through an HDMI cable. Video is awesome. Audio was awesome too through the HDMI cable.

To get true surround sound, I connected the audio from the dish box to the samsung HT system through an optical cable.

The problem: When watching HD content that has true surround sound, there are hiccups in the sound. Every so often the sound just vanishes for like 2-3 seconds and there is silence. This does not happen with SD content when the audio is not surround sound.

Anybody know what could be wrong? Does a screwed up optical cable cause something like this? I am doubting it since SD audio through the same cable has had no problems. Somebody might know what could be wrong?

Sounds like your HD provider is having issues johnjbruin

See - I doubt that. If I just listen to the audio from the TV directly that is coming through the HDMI cable - then I don't see the problem.

I tried keeping both sources on simultaneously - and the true surround will vanish for like 3 seconds - but during these 3 seconds - the regular sound from the tv is still there.

It has me scratching my head since I can't figure out what is causing this.

Some wild guesses to hold you until you can call Dish or search AVSForum.com:

Check the Dish box, see if you can tell it to just send audio to the digital out to the HT system and not also to the HDMI, it's possible sending both at once is more than it can handle.

It could also be problems with the 5.1 signal from orbit (separate band/channel from video + analog audio?) or problems with the original transmission: people in AVSForum say Discovery Channel routinely lets audio and video get out of sync, it could be some channel glitch.

Interesting - I mostly notice it on Discovery HD...

Do you have any links to any of these posts? I am not that familiar with AVSForums

Nope, but the Search there works well, try "Discovery Channel" in the Rear Projection Units forum

also, see if maybe you can get cable in your area. you should be able to get all the same features (HDTV, DVR), for the same price or cheaper. And you won't have to worry so much about dropouts because the signal is local.

my sound drops out fora second when the commericals come on because the sound goes from 5.1 to 2 speakers. it does the same thing going back to 5.1 speakers. i can also hear the relays clicking.. Ive gotten use to it but other folks think its annoying.

Givenm that you say it's mostly on Discovery Channel. what you are most likely experiencing is from the source. Given that movies are developed in True Surround to a far greater extent than any other source media (maybe some music videos). The most probable cause of audio hiccups is from Discovery Channel > Dish Network > Samsung Receiver . In that order.
I would ask if you experience this problem while watching a DVD in Surround mode. If it's clean chances are it's your Dish Sources.

The DVDs are clean - but the reason for that is that the Samsung Audio receiver is the DVD player itself.

This *has* happened on HBO-HD and SHO-HD also - but is very rare.

What I'm trying to find out is if there is a glitch in the decoder. Run another DVD player into the optical inputs and see if it burps.

Oh... I'll have to give this a shot tomorrow and update... Thanks for taking interest
