alphabetical order or not

[KimJensen]

Hello.

I have a ReadyNAS Duo and an MARANTZ av 7005 pre amp. When i in the MARANTZ choose my ReadyNAS Duo and then selects music and then all music, then comes the music list in a chaotic, non-alphabetical order.
I also have an iomega nas and when I choose the same there, then there's a list in a fine alphabetical order.
Can I get my ReadyNAS to do the same?

These are the same files that reside on the two nas.
My files are named Artist - music name.flac like this Adele - Rolling in the Deep.flac
