Re: Help with connection types

I hope this is my last post regarding issues with my receiver, but here it goes:

When I go from an HD channel to a non HD channel...or sometimes during Blu Rays, if I go from one section of the disc to another, there is a mechanical clicking sound coming from within my receiver.

Is this normal? people have said that it happens when the receiver picks up different audio signals. But I was watching The Avengers Blu Ray deleted scenes, and from one deleted scene to another, I received the clicking noise, but each deleted scene was in the same audio format..it doesn't happen though when I watch an entire movie or stay on the same channel

Is there anyway to prevent this clicking sound from happening?


Also, on my non HD channels, the image sometimes stutters a bit. This does not happen with the HD channels, only with SD channels...and since I use Comcast, most movie channels are in SD not HD

thanks again for all the help

Re: Help with connection types

Nah, you helped me out a lot

I think I will leave it at Linear PCM just in case of a loss in audio...I don't mind that my receiver says PCM or MuliCh

But thanks to you, I know to keep it at Direct

Re: Help with connection types

Linear PCM = the player is decoding the audio.
Bitstream = the player is passing the un-decoded audio to the AVR, which decodes it.

I'd go with whichever option gives you the best sound.

When doing so, I received a notice message saying that "Some audio from the BD may not be played unless I select Linear PCM"
My guess is that it's just a caution to you that the AVR the player is bitstreaming to may not be capable of decoding any secondary / supplemental audio that's in the stream. If your AVR handles it, no worries. If you notice audio missing, have your player handle the decoding.

And do you suggest to just use "Direct" for everything?
IMO, yes, unless you want to "matrix" a stereo source into multi-channel surround, in which case you'd switch over to ProLogic II or NEO:6.

Thanks, you have been a big help
Well, since you figured it out yourself, I wasn't really all that helpful...

Re: Help with connection types

I think I figured it out:

I changed the Setting: BD/DVD Audio Output Format HDMI from Linear PCM to Bitstream

Now, when I set it to "Direct," it appears as DTS 5.1 on my receiver.

When doing so, I received a notice message saying that "Some audio from the BD may not be played unless I select Linear PCM"

So should I keep it set to Bitstream even though I received this warning?

What are the disadvantages of using Linear PCM?

And do you suggest to just use "Direct" for everything?

Thanks, you have been a big help

Re: Help with connection types

OK, well according to the AVR's manual, it looks as though the MULTICH mode is the mode to be in if a device is feeding it multi-channel PCM audio.

Re: Help with connection types

I don't see any option to change that.

I am thinking that the PS3 only plays everything in PCM multichannel

Thanks, but what does Direct mean?
Direct means that the receiver will play exactly what is sent to it.

EDIT: I just checked to see the difference...my receiver won't let me select Direct when the PS3 is on. When I try to, it just reverts back to MULTICH
Perhaps your PS3 is decoding the audio and sending multi-channel PCM to the AVR? Check your PS3's settings and have it output "RAW" (I think that's the term I saw recently in a PS3 menu) to the AVR.

I understand it is a setting, but the description in the manual doesn't tell me much about what it means.

All I understand is that audio from the input source is output without surround sound processing.

thanks

Re: Help with connection types

Pg. 31 of the manual: Set your listening mode to "Direct". If your PS3 is outputting DTS-HD MA 7.1, that's what the receiver will play.
