Did you try saving it in wav in Audacity. This fixed any issues with 7.1 or Atmos files that couldn't be recognized in a FLAC container. My Oppo 103 doesn't like 7.1 files in FLAC but is okay with them in WAV.FLAC Files will work on my Sony player if put on a jump drive. FYI, I erase the jump drives and only put one album on each drive, so the drive "shouldn't" be an issue.
The ones I bought were Flac files. 96000 Hz 24 bit. They work fine. The one my friend gave me were ALSO Flac files 96000 Hz 24 bit. They don't.
My friends files open perfectly in Audacity. I resaved them to a new Flac file. That still didn't work. I tried to save them to 48000hz. That didn't work.
I tried resaving them again, creating a new Flac file in xAct. That didn't work either. Again, I brought the xAct version into Audacity, and it opens fine. Still, my Sony player doesn't recognize the file.
I don’t know with any certainty that I (or someone else) haven’t already made this suggestion, but goldwave (www.goldwave.com) opens FLAC files, allows playback and editing, and also has a very large choice of file formats for storage. It’s fairly cheap, easy to use, and has a free trial.
Well, the OP is having trouble with that software, so another program (with a free trial) wouldn’t hurt. We’re all grasping at straws here.Audacity is free and does that.
You can certainly open a FLAC file in Audacity, and save it as a WAV file at a higher or lower sample rate than its original SR, and higher or lower bit rate.
So I don't see the point in adding yet another piece of software.
