Someone please help 2nd post with no answers.

I posted this before with no answer some one help!! My reciever is cutting out all vocal when watching hd tv or blu ray not all the time, If i switch to a sound field instead of dd or dts, then i can hear voices again except i have to turn it up louder than normal, then i can sometimes switch back to dd or dts and it will work again. It's not my connections, it something with dd or dts, that is dealing with either my optical inputs or my reciever itself is failing. Just was hoping that someone would know exactly or has had the same problem. most importantly it's not ALL sound cutting out from my speakers it only the voices from all 3 front channels.

Voices are not seperately encoded, so that seems very unusual.

No idea what is causing it. If it was one speaker I might think a specific driver. First I'd verify the receiver is the problem by borrowing a different one. Then I'd suggest contacting your receiver manufacturer.

I've been racking my brain, it is weird it's as if someone hits the mute button on all vocals and only vocals all music or background noise in a show or move continue, i'm using optical for both ps3/bluray and directv. It does it with both but only in dd or dts formats. if i change to a sound field volume is lower but i can hear voices then usually. I cant use hdmi as much as i would love to, being my receiver only passes it thru to the tv, and does not receive any sound from the hdmi? I guess goin to another receiver is my only option. Any other ideas with the info i just gave you? thanks oh also it's a sony str dg-800

Except that you siad it's all three speakers I would think it was a problem with the center channel (where most dialog occurs): in which case there would be more PD that I could think to do.

I cannot imagine how it would be possible for only the voice portion of three channels to go out.

That seems almost impossible really.What AVR do you have? The vocal range is from about 350hz to 3.5k and that would also nullify every other instrument in those ranges as well.Is the some decoder set on your avr?

 

[Rickster71]

Has this been happening with different types of source material?
Is the problem consistent with different sources?
Is there an update for your AVR's software?

I would look at how the speakers are connected at the speaker terminals on the receiver. If the terminals for a particular channel are orientated vertically Positive on top and Negative on the bottom), it could be that the center channel is adjacent to one of the rear channels and if the center speaker's wire is on Center ch + and Rear ch +, it may have a signal but it wouldn't be correct. If the center channel sounds vaguely like it's in some kind of echo chamber, this may be hte cause but I haven't seen the make/model of receiver, either.

 

[JerryLove]

Just for fun, and I don't want to sound doubtful of your details, but try telling your AVR that you have no center channel attached. That will cause the AVR to phantom the center. If it is a problem with a center connection, or the amp-channel for the center or the like: then the problem should go away and we'd know better where to look.

First it's an sony str dg-800. is happens when watching HD content either directv and bluray. it effects DD and DTS, doesn't always do it either, My avr is a few years old i have no idea about software ver. I"ll look now. All i can do to explain is it's like the voices are very muffled or muted but all other sound is at same level. i'm lost

 

[airnmol]

HighFigh:....it's does have a little bit of an echo effect with what voices you can make out.

Jerry thanks for the input i will do that and see if it continues, when it does mess up if ever. Next question if i phantom my center and it doesn't cut vocals then what is the problem and solution? also if it still effects it then what next? Thanks for the ideas to narrow this down, keep em coming.

i'm not sure what you meant?

If it still occurs with a phantom center than I have no clue.

If the problem goes away, the most liklely causes would be connective (check all your wires etc), a problem with the center speaker (try replacing it temporarily with, say, a surround speaker and re-enabling center, and see if it works), the decoder (unlikely: to ospecifc) or the center amp (not very likely).

PD

What's that?

Anyway I think the center is cutting out intermittently. When you have a discreet center channel signal with DD the vocals are mostly there and when the channel cuts out ... well the vocals are gone but everything else stays. I think that with other DSP's there is an algorithm to take any frequencies that are equal in the L and R and pumps them out of the center too. If the center cuts out with that DSP, you would still have some dialog volume left but not as much.

I think you might have a bad solder connection somewhere in that signal path. A new rec'r is in order anyway that does what you want with HDMI audio. Have this one repaired for a secondary system in a different room ... but wait, that's my rock and roll fantasy ...

I'm just guessing ... it's not like I know anything.

Problem Determination.

Sorry. I thought it was in general use, but it may be jargon from my field.

What if the center-channel cut is a short at high load or internal connection problem? I think pinning down the part responsable is the first step. Though it may be the receiver: I'm not convinced that's the only option.

You and me both monkey.
