Jriver and Devialet

[Kunter]

I have a Macbook Air wired on a new Airport Express. My devialet 250 is also wired on the same Airport Express. My iTunes music library is on my Synology NAS 213+ (Wired also to Airport Express.). My entire music collection is in Apple Lossless (ALAC).

Here's the problem: When I listen to a playlist (m3u imported or manually on the spur of the momement) for a few minutes (time varies) one of the musical pieces starts playing very quickly like the chipmunks singing. What can I do to remedy the situation? Please help! I don't have this problem with iTunes but I don't want to use it because my music library is too big (3000 albums).

Sorry for my bad english.

Chipmunks visit my home as well from time to time when I am using Audirvana.

I wrote this to Devialet and their answer was:
