I have the same issue with my 203. The player is in a second system, and I have have a streamer in the system that does play the files, so tbh I never did anything about it
Oppo udp-205 DSD playback
I have all my Hi Res files on a 1tb usb dongle plugged into the front of the Oppo. All the FLAC files play back fine. The DSD file playback is inconsistent. According to the specs, the 205 should be able to play these files but it just skips right over them. Even DSD files of supposedly the same spec it will play one album but skip over the next one. I’m obviously missing something fundamental here. Anyone have a solution? Thanks
