Repeated tracks on multi-discs ripped from dbPoweramp

As this doesn't happen when you use UPnP compatibility mode in the Naim app, it seems to be a problem with the Naim app.

I tried the Naim app with a multidisc album but I don't see the problem. Have you tried clearing the UPnP cache in the Naim app?

If this doesn't help, try checking the track number tags in your files. For a multidisc album, the track numbers should go from 1..n on each disc.
