RailJet2012 sound problem

Hello I managed to find and download the above train.
However I am not getting any sounds playing when I run the game.
I have noticed that it uses .flac files for the sound and I'm wondering if this might not be the problem.
When loading I the following type of errors...
The file extension is not recognized - will be assumed to be a .wav file: C:\Users\Michael\Documents\BVE\Train\RailJet2012\wav/Run0.flac
The file extension is not recognized - will be assumed to be a .wav file: C:\Users\Michael\Documents\BVE\Train\RailJet2012\wav/Run1.flac
The file extension is not recognized - will be assumed to be a .wav file: C:\Users\Michael\Documents\BVE\Train\RailJet2012\wav/Run2.flac
... and so on.
Any help would be greatly appreciated,
With thanks Michael

Hmm, check the sound.cfg fIle and make sure that it is structured correctly.
