Topic: BlueRay Audio 24bit 192k not playing/showing correct sample rate
Hi there,
I'm trying to play back a high resolution audio recording from a BlueRay disc on a Philips bdp2900 BlueRay player connected to my RME ADI-2 DAC through the SPDIF coax connection and the State Overview shows that the sample rate is 16bit 48k. In the manual it says the RME is always the slave and the sample rate and bit depth is set by the source so the RME should switch automatically to 24bit 192k playback.
As there is no 16bit 48k audio file on the DVD, but it does play and I can hear music, I am thinking that either the DVD player is downsampling the audio before sending it to the ADI-2 or if the ADI-2 is downsampling it or simply not showing the correct numbers in the Overview menu?
When I switch the DVD player ON, the menu on the ADI-2 goes from showing --- to: sync - 48 SR - cons State - 16 Bit. That is the industry standard for PCM audio for film. Clock source shows as: SPDIF coax. The DVD player has PCM for audio playback in the settings (not Bitstream). Then I select the 2.0 Stereo 24bit 192 option of audio playback on the DVD menu and hit PLAY. - nothing changes on the ADI-2 DAC in terms of sample rate and bit depth.
I'm thinking either the DVD player is sending out Bitstream or the RME is interpreting the information incorrectly?
