UMC-1 audio decoding

[kaa1954]

And the other note worthy thing about the Oppo to get Hi-Rez is to set it 5.1 not 7.1

When set to 7.1 this statement kicks in:
"or 8 channels of audio with standard sample rate (up to 48kHz)."

Really? You can't get discrete surround back channel(s) with 96kHz audio from the Oppo?

Do any players support that? Granted, lossless 48kHz audio will still be way better (than DD or DTS), but I'd hate to lose resolution on all channels just to get discrete back channels!

I'm budgeting for an Oppo and two rear speakers in addition to the UMC-1/UPA-7 combo when I next upgrade, but maybe I should re-think some of that...

What page is this on?

I have the Oppo manual and can't find this statement anywhere other than the box talking about the 480p HDMI audio limitation.

Everything I see says LPCM up to 7.1 at 96Khz for HD audio.

It is my understanding that when you set it to 7.1 downmix, it will process any inputed signal to 7.1 as you are requesting it to do. It is matrixing the incoming stereo or multi-channel signal (downrezzing in this case) to 7.1. When set to 5.1 it does no matrixing of 5.1 info. To make this simple when set to 5.1 it only matrixes sources less than 5.1.
There is a whole thread on this over at AVS. Just search the Oppo 980-h.

That's not what the manual says. Are you sure you are referencing the BDPs and not the older 980H DVD player?

First, the BDP-983 manual shows the down mix setting only applies to the analog outputs, not HDMI connections. Also, it only down mixes to less channels, if set that way. It does not matrix 5.1 into 7.1.

well, I did get my Sony BD player to send "bitstream" to the umc by disabling the secondary audio mix option. so my umc is now showing dts-hd ma etc but discs like True Blood with its PIP commentary and its audio stream would now be mute.

I don't think I can get my HD DVD player to do this however.

As far as I know the only way to get the secondary audio is to disable bitstream from the player. I can't think of any player that lets you bitsteam the lossless codecs with the secondary audio.

The biggest problem with that is if you want to listen to the commentary you have to go back to your player settings and turn on secondary audio, or let the player decode to LPCM.

Some of the players (like the Oppo) will bitstream with secondary audio, but they mix and re-encode with a lossy format. DTS, in the case of the Oppo player.
