If I remember correctly I think I’ve seen that error code before myself and it occurred when trying to playback files that haven’t been fully populated into the app music library. Just leave it a few hours and try again to see if plays them then.
I assume you are viewing the files in the Server input/Local Music, which takes a while to scan them.
Viewing the files in the USB input, the basic folder view makes everything visible more or less immediately. I think this is what the OP is doing. Maybe worth using the server input to view the files and check that they have all been scanned before playing them. In any case it’s better than using the USB input.
Thanks @ChrisSU, I wasn’t aware you could access external drive via Server input/Local music - was using USB. Unfortunately neither server input or USB mode works, both modes I can see the folders/files but they all have 0:00 length and when I try select a file to play, the nova appears to load then skip to next tracks without playing.
exFAT is not officially supported by Naim streamers. I don’t know if this is your problem, but perhaps you can try putting an album on a different drive that is formatted in FAT32, NTFS or HFS and see if that works. Any USB drive will do - just a memory stick or whatever you can find.
After further troubleshooting I found the files were not playing on laptop/other devices as well - turns out the issue was related to how I copied the aiff files onto the SSD. I recently moved my collection to google one cloud storage and copied the files to the SSD direct from cloud. Although the files were visible and taking up storage, they weren’t copied over correctly.
I did a fresh copy from another hard drive and now works and loads fast on the nova.
On the current range of streamers, uniti and muso range, we officially support exFat, NTFS, HFS+ and APFS on USB mountable drives. We licence the official Tuxera drivers built for each processor type. This fact is a bit hidden though.
I remember exFat was released in one of the earlier 3.x releases and it was in the release notes. Very convenient, since Windows and macOS support out of the box without the limitations of FAT32.
(Though older/cheaper embedded system, TVs, … don’t support it.)
Seems the webpage/help does not get updated accordingly. (Tedious job, know; especially when the technical or product guys cannot easily update it themselves.)
