Finally got waveaudio installed by adding 'C:\Program Files (x86)\CodeGear\RAD Studio\6.0\lib\designied.dcp' to the 'requires' bit of the package.
(although when I installed TWavePlayer afterwards just deleted the entire WaveAudio palette and all components and replaced it with Delphi Area with just the single TwavePlayer !)
Anyway, I can't get any of the components to play WMA files that were recorded on my voice recorder.
TWave player would load it and WavePlayer1.Sound.Size correctly showed the length but it would not play anything after WavePlayer1.active; Waveplayer1.play and WavePlayer1.Sound.Position didn't change.
The Waveplayer demo from WaveAudio won't play wma files - give an error aboput wrong format - and debug shows the AudioFormat to be ''.
Don't these components read/play wma?
