I have a path forward. I'm going to download know playable music from I-Tunes to the SD card and see if the R6 will play them. That way I can confirm whether the problem is with the SD card/R6 or with the music file format.
Looks like I had bad flac files. I copied an Apple lossy file to the sd card and everything worked fine. I then re-formatted the sd card and reconstructed everything with flac files generated by a different ripping program and now everything works great. So much for VLC Media's ripping program.
