Thanks to all for your suggestions. I was able to make it work by transferring from my music NAS to the pono disk without using the pono softward, as Cerrot suggested. Now all is fine.
Ozzy, buying music from the Pono site doesn't require a pono player. You can buy just as from any site, but you do need to install the Pono software to download the music -- and then transfer to whatever folders you use for your music library. It's pretty intuitive, even I was able to figure it out. There may be other ways to download, but I'm pretty sure you need the Pono software, which if free.
fwiw, Neil's high rez albums are consistently very good, nice improvements over CD.
