24Bit 96Khz Hires audio out via coax possible?

Hi,

I am having some "fun and games" trying to get my Panasonic Blue-ray player (BD85) to send 24 bit hi-res audio to my external stereo DAC (Audiolab M-DAC) and wondered if there was any advise out there.

I am connecting the player to the MDAC via Coax.

The player has all the correct settings from what I can see:
PCM output
Stereo Downmix
PCM Down conversion off (to allow 96Khz according to the manual)
HDMI Audio off (Tried to on, but no difference).
Latest Firmware installed.

An example disc is the Rolling stones Grrr! Blue ray which as 24 bit 96Khz PCM Stereo sound track. When I play it back the M-DAC shows 16bit 48Khz. If its relevant, the software version is A08.

I am sure there is a way as all my equipment and cables seem to support this.

Any ideas / advise VERY welcome!

By the way I get the same results from the Led Zep Celabration Day Blueray which is 24 bit 48Khz. i.e. the M-DAC shows 16bit 48Khz.

I see in the manual it mentions:

≥ Signals are converted to 48 kHz despite the settings across in the following cases:
– when the signals have a sampling frequency of 192 kHz
– when “BD-Video Secondary Audio” is set to “On”
– when the disc has copy protection

First two, no problem I have it covered but the last one could be the problem, in that case it just wont work - anyone know if that is the case?


Cheers...

Thanks jbrower1,

You gave me an idea which i tried:

I already connect my TV (a Panasonic G20) via HDMI. So I took the Optical out from the TV to my M-DAC in the hope it would just pass through what it was given by HDMI. Not so, its still 48Khz not 96.... interestingly though the M-DAC is showing it is receiving 24bit.

Any thoughts?

Cheers.
