Sony DVP-NS905V DVD Player - CD player measurements

[Scytales]

Although it would be odd, it is a possibility that when the player is configured in the audio menu to use the 5.1 analogue output, then the player read only the multichannel area of an SA-CD disc and don't even try to read the stereo 2 channels area. Stereo only SA-CDs would then not be read at all. A check is in order. I will try stereo only SA-CDs on my DV-868AVi, which should have about the same built-in software than the DV-565, at the earliest opportunity.

The salesman told me it would but I seem to recall trying it and it not working.

It was a long time ago though so maybe I'm mistaken about that.

I'm pretty certain it does not work with DVD-A, I clearly recall testing that. Maybe I had it configured wrong but I went through all the menu options with no joy.

Multi-channel SACD I did get working and it will play the CD layer of hybrid SACD.

The relevant owner's manual states the contrary. Playback of DVD-Audio is thoroughly described: https://www.manualslib.com/manual/7...html?page=44&term=dvd-audio&selected=1#manual

But, it is also stated that copy-protected DVD-Audio discs cannot be played through any digital outputs and can only be played back through the analogue outputs.

Did you use this player with one of its digital outputs ?

No it was analogue output - the DVD-A was Steely Dan 'Gaucho.'

The disc played perfectly on a friend's TOTL Oppo unit, and also plays fine on the cheaper Oppo I have.

I think the issue may be that the DTS surround sound DVD-A is supported by the 565A, but the 24/96 stereo is not.

I don't think so.

Paul Miller has tested a DV-565A for Hi-Fi-Choice (Issue #248, page 67), including with a DVD-A test disc that have 96 and 192 kHz sample rate signals, and it worked.

The DV-565A is based upon an ST Microelectronic STe5588 DVD decoder chip which includes an MLP (Meridian Lossless Packing) decoding block, so it cannot be a matter of not being able to unpack PCM data compressed with MLP.

It is most probable that either your exemplar of player or the DVD-A itself (bad authoring?) is at fault, or that there was a user mistake.

It may be that your player was configured in the audio menu to use the 5.1 analogue output and for that reason, it didn't read the stereo 2 channel content that is on the disc.

Ah fair enough then. As I said that DVD-A does play on other units so clearly the fault is not there - which just leaves user error.
