Sony Rdr-hx910 Dolby Digital Sound

[mors]

Until recently I have used my 910 mainly for recording duties,but have just started renting DVDs.I am now using the 910 as a dvd player with my AV9/P7 combo.Despite trying every permutation in the Audio Setup menu I just seem to get Dolby Digital 2ch downmix.Is this norma?I am using the 910 because of the HDMI connection.Would I be better using my old Toshiba 900e pending next upgrade?
Any advice would be greatly appreciated.

I'm using a 910 HXD feeding an AV9. I don't use it to watch DVDs very often as I have a dedicated player, but when I've watched 5.1 DVDs ISTR that I got 5.1 sound.

You need to check the setup of your 910 and also the AV9. The 910 manual as clear instructions for setting-up the digital audio out options. Dolby Digital is clearly listed in my manual. You may also need to manually set the audio type on the AV9 if it doesn't auto-sense the data feed from the 910.

How is the 910 connected to the amp you are using,is Dolby Digital set to output DD or is it set to PCM,is the Digital output turned on?

The options set sound about right. Given that you're getting 2-channel sound it would seem that perhaps the options on the AV9 aren't set correctly.

What happens when you cycle through the Mode options on the AV9 whilst playing a DVD on the Sony? Can you select DD5.1? If not, then your AV9 might not be set-up correctly.

If the AV9 seems OK, what happens if you use a dedicated DVD player using the same interconnect and input on the AV9?

On my AV9, only the DVD input behaves as expected, in that it automatically selects the correct audio mode. On the inputs fed by my Sony HDD, the AV9 sees the source as 'Digital Stereo' until I start playback from the HDD, then it will 'remember' the last setting that I used - DD2.0, DDPLIIx, etc.

To be honest, I'm not sure if I need to tweak the input parameters on the inputs on the AV9 that I use for my Sony HDD, but as I mainly use the HDD I find that I need to select the decoding type manually. For example, NYPD Blue recorded from More4 is originally recorded in Dolby Surround. I have to manually select Dolbly Digital PLIIx Movie here because the Arcam doesn't see the correct data stream by default.

I suspect that buried in the AV9 manual is exactly what you need, assuming that a test with a dedicated DVD player on the same input as the Sony behaves in the same way. If not, then perhaps you might have a duff Sony box.
