Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
Oppo UDP-203 via HDMI
Problem:
I am attempting to play 5.1 audio over HDMI to Oppo player using FLAC and DSD files. I am not trying to avoid conversion of DSD to PCM
- If I use the “roon ready” version of the Oppo it always downmixes to 2-ch.
- If I use the Oppo as an hdmi-connected system sound device configured for 5.1, all PCM files play fine, any attempt to play a DSD file results in “failed to initialize the audio device.” Roon and Oppo are both set to use PCM, both set to 5.1, Oppo is in exclusive mode, 192k/24 in both Roon and Windows. This configuration works fine in JRiver Media Center and Foobar2000.
Library Details:
Library is on Dell desktop mentioned above.
Questions:
Is it a official that the Roon-ready Oppo 203 cannot play multichannel?
Should Roon be able to play DSD mutlichannel from an Oppo 203 over HDMI?
In this scenario what causes a “failed to initialize the audio device?”
