I have Firefly server installed on my D-Link DNS332 and Firefly client installed on my Windows Vista desktop. The server has been configured with;

extensions = .mp3,.m4a,.m4p,.flac,.ogg
ssc_codectypes = mp4a,ogg,flac,alac

but the client fails to play *.m4a files. It simply passes over them. Will the windows client play this type of file?
