Can anybody help me. I recently bought a AW300 speaker and although it quite happily plays MP3 files from my media server it refuses to play any flac files.

I upgraded the firmware and it now shows in airstudio as V H4.31S.

In airstudio I select a flac file and it comes up with the playing screen, but when I press the 'play' button nothing happens, whereas if I select a MP3 encoded track it starts almost immediately..
